(GW0742 also known as GW610742)
Cardarine also called GW501516 and a stronger version called GW0742 are a class of supplement called ‘exercise in a pill’ or ‘endurance boosters’. They are not stimulants, SARMS or steroids, but they are banned in sport. These compounds escaped into the fitness industry a few years ago, so they are not new or secret and are used regularly by fitness enthusiasts, athletes and bodybuilders.
‘Exercise-in-a-pill’ boosts athletic endurance by 70 percent:
Salk Institute scientists, building on earlier work that identified a gene pathway triggered by running, have discovered how to fully activate that pathway in sedentary mice with a chemical compound, mimicking the beneficial effects of exercise, including increased fat burning and stamina. The study, which appears in Cell Metabolism on May 2, 2017, not only deepens our understanding of aerobic endurance, but also offers people with heart conditions, pulmonary disease, type 2 diabetes or other health limitations the hope of achieving those benefits pharmacologically.
“It’s well known that people can improve their aerobic endurance through training,” says senior author Ronald Evans, Howard Hughes Medical Institute investigator and holder of Salk’s March of Dimes Chair in Molecular and Developmental Biology. “The question for us was: how does endurance work? And if we really understand the science, can we replace training with a drug?”
Developing endurance means being able to sustain an aerobic activity for longer periods of time. As people become more fit, their muscles shift from burning carbohydrates (glucose) to burning fat. So researchers assumed that endurance is a function of the body’s increasing ability to burn fat, though details of the process have been murky. Previous work by the Evans lab into a gene called PPAR delta (PPARD) offered intriguing clues: mice genetically engineered to have permanently activated PPARD became long-distance runners who were resistant to weight gain and highly responsive to insulin—all qualities associated with physical fitness. The team found that a chemical compound called GW1516 (GW) similarly activated PPARD, replicating the weight control and insulin responsiveness in normal mice that had been seen in the engineered ones. However, GW did not affect endurance (how long the mice could run) unless coupled with daily exercise, which defeated the purpose of using it to replace exercise.
In the current study, the Salk team gave normal mice a higher dose of GW, for a longer period of time (8 weeks instead of 4). Both the mice that received the compound and mice that did not were typically sedentary, but all were subjected to treadmill tests to see how long they could run until exhausted.
Mice in the control group could run about 160 minutes before exhaustion. Mice on the drug, however, could run about 270 minutes—about 70 percent longer. For both groups, exhaustion set in when blood sugar (glucose) dropped to around 70 mg/dl, suggesting that low glucose levels (hypoglycemia) are responsible for fatigue.
To understand what was happening at the molecular level, the team compared gene expression in a major muscle of mice. They found 975 genes whose expression changed in response to the drug, either becoming suppressed or increased. Genes whose expression increased were ones that regulate breaking down and burning fat. Surprisingly, genes that were suppressed were related to breaking down carbohydrates for energy. This means that the PPARD pathway prevents sugar from being an energy source in muscle during exercise, possibly to preserve sugar for the brain. Activating fat-burning takes longer than burning sugar, which is why the body generally uses glucose unless it has a compelling reason not to—like maintaining brain function during periods of high energy expenditure. Although muscles can burn either sugar or fat, the brain prefers sugar, which explains why runners who “hit the wall” experience both physical and mental fatigue when they use up their supply of glucose.
“This study suggests that burning fat is less a driver of endurance than a compensatory mechanism to conserve glucose,” says Michael Downes, a Salk senior scientist and co-senior author of the paper. “PPARD is suppressing all the points that are involved in sugar metabolism in the muscle so glucose can be redirected to the brain, thereby preserving brain function.”
Interestingly, the muscles of mice that took the exercise drug did not exhibit the kinds of physiological changes that typically accompany aerobic fitness: additional mitochondria, more blood vessels and a shift toward the type of muscle fibers that burn fat rather than sugar. This shows that these changes are not exclusively driving aerobic endurance; it can also be accomplished by chemically activating a genetic pathway. In addition to having increased endurance, mice who were given the drug were also resistant to weight gain and more responsive to insulin than the mice who were not on the drug.
“Exercise activates PPARD, but we’re showing that you can do the same thing without mechanical training. It means you can improve endurance to the equivalent level as someone in training, without all of the physical effort,” says Weiwei Fan, a Salk research associate and the paper’s first author.
Although the lab’s studies have been in mice, pharmaceutical companies are interested in using the research to develop clinical trials for humans. The team can envision a number of therapeutic applications for a prescription drug based on GW, from increasing fat burning in people suffering from obesity or type 2 diabetes to improving patients’ fitness before and after surgery.

EPO activity has been linked to angiogenesis, neuroprotection, cardioprotection, stress protection, anti-inflammation and especially the energy metabolism regulation that is recently revealed.
The primary physiological function of EPO system is to stimulate erythroid progenitor cell production to provide adequate red blood cells and oxygen delivery. However, emerging evidences revealed previously less realized roles of EPO and EpoR(receptor) signaling beyond hematopoietic system. For example, EPO stimulated angiogenesis via endothelial cells in cardiovascular system contributes to cardioprotection to ischemic injury. EPO also provides neuroprotection during ischemic/hypoxic stress or disease via stress induced EPO production and EpoR expression in the brain to exert the antiapoptotic, oxygen delivery and anti-inflammatory effects.
The protective function and the wound healing and repair role of EPO in skeletal muscle during ischemic/injury were also demonstrated.
These pleiotropic activities of EPO in non-erythroid system strongly suggest therapeutic potential of EPO beyond its traditionally primary clinical application in hematopoietic system. More interestingly, recently published data confirm the tight link between EPO/EpoR signaling and energy metabolism and homeostasis.
EPO administration could protects us from diet induced obesity, promotes energy expenditure, reduces fat mass accumulation and improves glucose intolerance and insulin resistance. The loss of EPO activity in non-hematopoietic system leads to glucose intolerant and insulin resistant with the development of obesity. EPO activity is also demonstrated to play a role in central regulation of appetite. The crosstalk between EPO and other important energy sensors including PGC-1α, Sirt1 and AMPK further provides a mechanism for EPO regulating energy homeostasis. Although these novel findings highlight the possible therapeutic potential of EPO in non-hematopoietic diseases. Further studies are required to uncover the detailed mechanism by which EPO regulates central control of energy homeostasis and energy metabolism in multiple tissues.
The manufacturer of the EPO powder vials we usually sell recommends reconstituting the powder with 1ml sterile water for injection (WFI, 0.9% sodium chloride) and using the contents of the vial *immediately*. Any leftover EPO should be discarded. Likewise a sterile WFI vial or ampoule must never be re-used. Tips for reconstituting EPO powder vials can be found further down this post.
Recommended WFI product (supplier not affiliated to us)
The potency of any pharmaceutical EPO brand may vary significantly from the IU declared on the label. An EPO vial or syringe may in some cases contain 150%+ of the labelled IU (this was once reported for the brand of powder vials we usually sell). Likewise much lower than the labelled IU is possible. Even significant variations in labelled vs actual IU for different batches of the same product have previously been reported for more than one brand. Closely monitoring blood values including hemoglobin and hematocrit is always crucial for any person using EPO, even when repeating a past schedule of doses with the same brand…even if blood values were closely monitored on that past schedule!
Multi-dosing from a vial
– Vials could be multi-dosed for up to 21 days after reconstitution by instead using sterile bacteriostatic saline (contains 0.9% sodium chloride + 0.9% benzyl alcohol). However, doing this may lead to detrimental changes to the EPO protein, reducing potency and increasing health risks to an end user (e.g. increased chance of an immune response due to increased aggregation of the EPO). These changes may occur at the time when bacteriostatic saline is first introduced into the vial and/or during subsequent storage. The potency and safety profile of the liquid may be vastly reduced by the 20th day after reconstitution.*
– Between doses, keep liquid EPO refrigerated at a stable temperature (4-5 Celsius).
– Multi-dosing also greatly increases the risk of coring.**
– Multi-dosing without bacteriostatic saline would not be advisable due to the high risk of bacterial growth inside the vial (even if using up the vial over a short timespan).
– Medications containing benzyl alcohol are contraindicated in newborns and infants as fatal reactions have previously occurred. They are also contraindicated in pregnant or lactating women, as fetuses and infants exposed to benzyl alcohol in utero or in breast-fed milk are also at risk of fatal reaction.
– We only recommend using bacteriostatic saline drawn from vials made by Hospira. Available from here (supplier not affiliated to us).
*EPO produced in the USA (Epogen and Procrit brands) is available in multi-dose liquid vials containing 1.1% benzyl alcohol, however this does not mean that adding bacteriostatic saline to powder vials will have an equal or similar effect on the EPO as the benzyl alcohol does in Epogen/Procrit multi-dose vials. This is due to a different manufacturing process for the Epogen/Procrit multi-dose vials, which contain ready-to-use liquid. The patient instructions for Epogen/Procrit multi-dose vials state that the vials should be discarded within 21 days of initial needle entry.
**There is a longstanding recommended technique of needle insertion into a medication vial that reduces the risk of coring. The needle should be inserted at a 45–60° angle with the opening of the needle tip facing up (i.e., away from the stopper). A small amount of pressure is applied and the angle is gradually increased as the needle enters the vial. The needle should be at a 90° angle just as the needle bevel passes through the stopper.
Tips for reconstituting EPO powder vials:
(This is NOT a complete instructional)
– Always disinfect the vial rubber top with a sterile pre-injection wipe (70% isopropyl alcohol) and allow to dry completely before inserting needle.
– Reconstitute each vial with the exact volume specified by the manufacturer (1ml for our usual brand).
– Do not reconstitute a vial until ready to use it.
– Use the technique above** to minimize risk of coring.
– Add the sterile WFI or bacteriostatic saline to the powder vial very slowly (drop by drop down the vial wall rather than directly onto the powder). Then leave it to sit dissolving for several minutes before gently swirling and rotating/inverting the vial to *completely* dissolve the powder. Do NOT shake the vial.
– Draw the EPO liquid into syringe very slowly. Transferring the liquid quickly may damage the EPO.
ALL PRODUCTS SHIPPED FROM EUROPE! Pay with any credit or debit card. We ship worldwide, with many customers in USA, Canada, UK, France, Germany, Spain, Italy, Australia and many more.
Admittedly we are biased when it comes to this, but nonetheless we figured this would be a useful exercise for our existing and potential customers looking to buy any research chemical online via a Google search. Or any product whatsoever for that matter.
A simple search for “buy epo” or “buy erythropoietin” will yield several web shops, included those listed below. Some very basic checks on these domains could save you from ending up empty handed after spending your hard earned money.
For each of the following, we conducted a WHOIS check, did a quick search around for customer reviews and made a basic common sense analysis regarding the legality of the products being sold.
24hoursppc.org – Clearly an illegal web shop, these kind of sites are liable to being shut down without warning by a regulatory authority, after which your order is unlikely to ever be fulfilled. This site is hosted on a server controlled by MSC Hosting, a UK based company under the jurisdiction of the UK courts, the laws of which are clearly violated by this website. We also found a negative review from 2007 here. Anyone website who truly values their reputation would surely address a complaint of this nature within a reasonable timeframe, especialy as the same complaint was referred to on this high ranking review site.
drs-labs.com – Likewise liable to being shut down due to selling controlled substances (HGH and HCG) without a licence on a Canadian registered and hosted domain name. Also their erythropoietin and other products are not made in GMP facilities, or at least can’t be verified as such. Perhaps the products are genuine but it throws the purity and dose accuracy into question. Although one absolutely shocking review here reports that “They mixed the labels on GHRP-6 and apparently mislabeled with Ipamorelin” and includes a response that the “ACE 031 from drs is fake”. As above, DRS Labs did not publicly address this review on the page in question, despite having the opportunity to do so for 2 years.
Erythropoietin.org – The WHOIS check reveals the domain was registered by [email protected], a Google search of which would lead one to the safe conclusion that this is a scam website. Unlikely that you will receive any product let alone EPO.
Stay safe out there and remember that here at Erythrobio we are more than happy to fulfil low cost sample orders so you can test our genuine, pharmaceutical grade, GMP manufactured products!
EPO-Boost, a supplement containing various vitamins, minerals and herbal extracts, promises much through it’s name alone, but we decided to ask the questions: does it really boost endogenous EPO levels in human subjects? If so, by how much? Does it represent good value for money?
Without any double-blind randomized placebo-controlled clinical trial results to directly back their claims, we can only analyze the presence of individual ingredients as follows:
Vitamin C – low plasma levels linked to erythropoietin resistance(1), intake increases absorption of oral non-heme iron(2), improves utilization of high ferritin stores(7)(8)
Vitamin B-3 – Deficiency a.k.a. Pellagra may lead to anemia, though a direct effect is unclear(10)
Folic Acid – red cell folic acid levels known to be depleted in the same way as B6(3), plus supplementation can significantly enhance the response to erythropoietin treatment in anemic patients with chronic renal disease(4). Anemia due to folate deficiency possible.
Vitamin B12 – deficiency can lead to pernicious anemia or increase resistance to EPO(5)(6)
Iron – apart from anemia brought about by a serious deficiency, supplementation of iron is required to achieve optimal response to erythropietin treatment(8)
BodyEndurance(TM) Complex and Alpha-Lipoic Acid – the primary ingredient here, echinacea purpurea extract, was shown to increase serum EPO levels by up to 63% during a 4wk study of oral supplementation at 8g/day.(9) Out of the remaining ingredients, we are unaware of any that directly stimulate EPO levels, but the addition of these may increase the total iron content and absorption as well as oxidative stress that may limit the effectiveness of any EPO increase.
It is immediately clear that there is only one ingredient that has been clinically proven to increase serum EPO levels and that is echinacea purpurea extract. Based on a generous assumption of 2g per capsule (we are kept in the dark regarding the exact dosage, but it is the main ingredient of the BodyEndurance(TM) Complex which totals 2.1g per capsule), we can see that the total echinacea purpurea dose is in line with that of the study referenced above.
Unfortunately this study did not result in ANY change in Hemoglobin, Hematocrit or RBC count!! Although erythropoietin has other benefits which we will address in later articles, it is safe to conclude that the purpose of injecting recombinant human erythropoietin or boosting EPO levels by other means (e.g. hypoxic exposure) is normally a resultant increase in the oxygen carrying capacity of the blood via enhanced hemoglobin content.
As for the remaining ingredients, these very well might increase the effectiveness of this echinacea purpurea stimulated EPO production, but to an extent capable of significantly increasing hemoglobin content seems unlikely, unless the user is already anemic due to iron/B6/B12/folate deficiency.
When one considers the relatively cheap cost of echinacea purpurea extract bought separately and the incredibly low content of iron in EPO-Boost, we struggle to reach any conclusion other than this product is very poor value for what can only be described as a mild effects.

Since first appearing on the market, Recombinant Erythropoietin preparations have called for 2-3x weekly dosing schedules. And at first glance this appears to be a logical approach, particularly considering the half life of intravenous preparations being limited to ~8.5 hours(1).
With the arrival of NESP (Novel Erythropoiesis Stimulating Protein, a.k.a. Darbepoetin alfa) and an IV half-life 3x longer, an obvious opportunity to market an alternative to Epoetin, one that didn’t need to be injected more than once a week.
The fact remains however that subcutaneous Epoetin administration results in a large half-life range(2) of 16-67h. In other words a median half-life of 41.5h. Barely differing to the 48.8h half life of subcutaneous NESP(3)!
And yet subcutaneous NESP is recommended for 1x weekly dosing. Why not take Epoetin 1x weekly instead?
Well that question has since been answered by a 2000 Swedish study who found NO difference between 1x versus 2-3x weekly Epoetin (same total weekly dose).(4)
In fact, as far back as 1992 a study conducted by the Chinese University of Hong Kong uncovered “similar responses” between 1x and 2x weekly subcutaneous administration.(5)
Furthermore it was since revealed that as little as once MONTHLY Darbepoetin alfa was effective at maintaining Hemoglobin levels in stable dialysis patients.(6)
One might conclude that any patient considering 1x weekly subcutaenous Darbepoetin alfa in the interests of convenience may very well reduce their costs considerably by opting for 1x weekly rhEPO instead.
