Dalton and colleagues reported in the Journal of Cachexia, Sarcopenia and Muscle in 2011 that twelve weeks increased total lean body mass and stair climbing power against placebo in elderly volunteers, and Dobs and colleagues reported comparable lean mass findings in Lancet Oncology in 2013. Andarine (S-4) stopped at preclinical work: Gao and colleagues showed in Endocrinology in 2005 that it restored muscle and bone in castrated rats with only partial prostate stimulation.\u003c\/p\u003e \u003cp\u003eCardarine (GW-501516) is a PPAR delta agonist rather than a SARM. Oliver and colleagues reported raised HDL in obese monkeys in PNAS in 2001, and Narkar and colleagues reported increased running endurance in mice in Cell in 2008. Development was discontinued after long term rodent studies reported tumours across multiple organ systems. Stenabolic (SR-9009), described by Solt and colleagues in Nature in 2012, has no human data and later work questioned its mechanism.

The first, in Biological and Pharmaceutical Bulletin in 2011, described YK-11 as a partial agonist of the androgen receptor and reported that it induced myogenic differentiation in C2C12 mouse myoblasts more strongly than dihydrotestosterone did, with a different pattern of gene activation.\u003c\/p\u003e \u003cp\u003eA follow up paper from the same group in 2013 reported that YK-11 increased expression of follistatin in those cells. Follistatin binds and inhibits myostatin, the protein that acts as a brake on skeletal muscle growth, and this single in vitro finding is the origin of every description of YK-11 as a myostatin inhibitor. It is worth being precise about what was shown: increased follistatin expression in a mouse muscle cell line, not measured myostatin inhibition in a living animal, and certainly not in a person.\u003c\/p\u003e \u003cp\u003eThere are no animal efficacy studies, no pharmacokinetic data, no toxicology package and no human trials of YK-11 in the peer reviewed literature. Because it is a steroidal molecule with a 17 alpha methyl group, chemists have raised the expectation of hepatic strain associated with that structural feature in related compounds, but this has not been formally studied for YK-11. Of all the compounds on this site, YK-11 has the thinnest evidence base relative to how confidently it is described elsewhere.\u003c\/p\u003e \u003ch2\u003eQuality and testing\u003c\/h2\u003e\n\u003cp\u003eDexterz Labs products are manufactured in the UK to a fixed strength per capsule with the batch number printed on every bottle.

That paper describes the discovery chemistry and the preclinical work: in castrated rats the compound produced anabolic activity in levator ani muscle comparable to testosterone while leaving the prostate largely unaffected, and in a primate study it increased lean body mass over twenty eight days. The selectivity ratio reported in that work is the origin of almost everything written about the compound since.\u003c\/p\u003e \u003cp\u003eSubsequent academic interest has run in two directions. Jayaraman and colleagues reported in Endocrinology in 2014 that RAD-140 had neuroprotective activity in cultured rat neurons and in a rat model, work that treated the compound as a possible androgen replacement for the brain rather than for muscle. Separately, Radius Health investigated RAD-140 in androgen receptor positive breast cancer, and a phase I trial in that indication was registered. No peer reviewed trial has reported lean mass or strength outcomes for RAD-140 in healthy human volunteers, which is the central gap in its evidence base.\u003c\/p\u003e \u003cp\u003eThe safety literature that does exist in humans comes from case reports rather than trials. Several papers in hepatology and internal medicine journals since 2019 have described cholestatic or mixed pattern liver injury in people who took products sold as RAD-140, sometimes alongside other compounds and often without any analysis of what the product actually contained. Preclinical work also shows the expected suppression of endogenous androgen production.

The best known is the phase II study reported by Dalton and colleagues in the Journal of Cachexia, Sarcopenia and Muscle in 2011, which gave 159 healthy elderly men and postmenopausal women enobosarm or placebo for twelve weeks. Total lean body mass increased in a dose related way and stair climbing power improved. Doses used in that published research ranged from 0.1mg to 3mg daily.\u003c\/p\u003e \u003cp\u003eDobs and colleagues published a further phase II trial in Lancet Oncology in 2013 in patients with cancer related muscle loss, again reporting increases in lean body mass against placebo. The later phase III POWER trials in non small cell lung cancer met their lean mass endpoint but did not meet the co-primary physical function endpoint, which is the reason enobosarm was never licensed. That context is usually left out of retail copy: the compound did what it was designed to do to tissue mass and still failed to show the functional benefit regulators wanted.\u003c\/p\u003e \u003cp\u003eThe pharmacology is straightforward. Ostarine is a non steroidal partial agonist at the androgen receptor with a preference for muscle and bone over prostate tissue, which is what the word selective in the name refers to. Reported findings across the trials include reductions in HDL cholesterol and in sex hormone binding globulin, and suppression of endogenous testosterone at the higher doses studied. Case reports of drug induced liver injury associated with ostarine containing products have appeared in the hepatology literature, though in several of those cases the product was never analysed.\u003c\/p\u003e \u003ch2\u003eQuality and testing\u003c\/h2\u003e\n\u003cp\u003eDexterz Labs products are manufactured in the UK to a fixed strength per capsule with the batch number printed on every bottle.

Seventy six healthy young men received placebo or LGD-4033 daily for three weeks, at doses used in that published research of 0.1mg, 0.3mg and 1mg. Lean body mass rose in a dose dependent fashion, reaching roughly 1.2kg above placebo in the 1mg group over just twenty one days, with no change in prostate specific antigen. The compound was well tolerated over that short window.\u003c\/p\u003e \u003cp\u003eThe same study recorded the findings that responsible discussion should always carry alongside the lean mass figure. Total testosterone, sex hormone binding globulin, free testosterone, HDL cholesterol and triglycerides all fell in a dose dependent manner, and follicle stimulating hormone was suppressed. Hormone levels returned towards baseline during follow up after the three week course ended. A later phase II programme in patients recovering from hip fracture reported increases in lean body mass, but the full data set has never been published in a peer reviewed journal.\u003c\/p\u003e \u003cp\u003eMechanistically LGD-4033 is a high affinity, high selectivity ligand for the androgen receptor with an oral bioavailability and half life, around 24 to 36 hours in the published pharmacokinetic work, that suit once daily administration in a study protocol. It binds the receptor considerably more strongly than ostarine does, which explains why the suppression of endogenous hormones appears at much lower milligram figures. Published case reports have described liver injury in people who took products sold as LGD-4033, and in the cases where the product was analysed the contents frequently did not match the label.\u003c\/p\u003e \u003ch2\u003eQuality and testing\u003c\/h2\u003e\n\u003cp\u003eDexterz Labs products are manufactured in the UK to a fixed strength per capsule with the batch number printed on every bottle.

It is a non peptide agonist at the growth hormone secretagogue receptor GHS-R1a, the receptor that ghrelin binds. Being a small molecule rather than a peptide, it survives digestion, which is why Merck developed it as a once daily oral alternative to injected growth hormone in the 1990s. It does not touch the androgen receptor and the trials did not report suppression of testosterone.\u003c\/p\u003e \u003cp\u003eThe central paper is Nass and colleagues in Annals of Internal Medicine in 2008. Sixty five healthy adults aged 60 to 81 took 25mg of MK-677 or placebo daily for a year. IGF-1 rose to levels typical of young adults and fat free mass increased by about 1.1kg relative to placebo, while fat mass did not change significantly and measures of strength and function did not improve in step with body composition. Svensson and colleagues, writing in the Journal of Clinical Endocrinology and Metabolism in 1998, found increased fat free mass and basal metabolic rate in obese men over two months, alongside raised fasting glucose and reduced insulin sensitivity. Copinschi and colleagues reported increased stage IV and REM sleep in a crossover study in 1997.\u003c\/p\u003e \u003cp\u003eThe counterweight is equally well documented. A 24 week study in older patients recovering from hip fracture, reported by Adunsky and colleagues, was stopped early because of a higher rate of congestive heart failure in the treated group. Increased appetite was recorded in every trial, which is expected for a ghrelin receptor agonist, along with transient lower limb oedema, muscle pain and lethargy in the early weeks. Reduced insulin sensitivity was consistent and is the principal reason the compound was never approved. Doses used in the published research ranged from 10mg to 50mg once daily.\u003c\/p\u003e \u003ch2\u003eQuality and testing\u003c\/h2\u003e\n\u003cp\u003eDexterz Labs products are manufactured in the UK to a fixed strength per capsule with the batch number printed on every bottle.

Oliver and colleagues reported in the Proceedings of the National Academy of Sciences in 2001 that GW-501516 raised HDL cholesterol and lowered triglycerides and insulin in obese rhesus monkeys, an effect attributed to activation of the PPAR delta nuclear receptor and downstream changes in fatty acid oxidation and reverse cholesterol transport. Small human trials in the mid 2000s in people with metabolic syndrome reported reductions in plasma triglycerides and liver fat.\u003c\/p\u003e \u003cp\u003eIts wider fame comes from Narkar and colleagues, writing in Cell in 2008. That study showed that PPAR delta activation combined with exercise, and AICAR alone, increased running endurance in mice and shifted skeletal muscle towards oxidative fibre characteristics. The paper was widely reported as an exercise mimetic, and it is the direct source of the endurance framing that surrounds this compound. It is worth reading the paper carefully: the strongest endurance effect in trained mice came from the combination of the compound with training, not from the compound alone.\u003c\/p\u003e \u003cp\u003eDevelopment was discontinued. Long term rodent carcinogenicity studies conducted during the programme reported tumours across multiple organ systems at the doses tested, and GlaxoSmithKline ended work on the compound.

The paper described SR9009 and its sibling SR9011 as synthetic REV-ERB agonists and reported that, in mice, they altered circadian behaviour and gene expression, reduced fat mass in diet induced obese animals and improved several metabolic markers. The compound was designed as a chemical tool for studying the clock, and that is still its main use in academic work.\u003c\/p\u003e \u003cp\u003eWoldt and colleagues followed in Nature Medicine in 2013 with work connecting REV-ERB alpha to mitochondrial content and autophagy in skeletal muscle, reporting increased exercise capacity in mice treated with SR9009. This paper is the origin of almost every endurance claim made about the compound. The critical caveat arrived later: Dierickx and colleagues, publishing in the Proceedings of the National Academy of Sciences in 2019, found that SR9009 produced effects in cells that lacked REV-ERB entirely, which means at least some of its activity is off target and not explained by the mechanism it is named for.\u003c\/p\u003e \u003cp\u003eThere are no published human trials of SR-9009 of any kind.

The published characterisation is preclinical: receptor binding, tissue selectivity in castrated rat models, and oral activity.\u003c\/p\u003e \u003cp\u003eA second strand of the published work looked at the central nervous system rather than at muscle. Studies in castrated rats examined whether ACP-105 could restore aspects of spatial memory performance, on the reasoning that androgen receptors in the hippocampus contribute to cognition. That line of enquiry mirrors the neuroprotective work published on RAD-140 and is a reminder that these compounds were designed as research tools for endocrinology rather than as sports supplements.\u003c\/p\u003e \u003cp\u003eThere are no published human trials of ACP-105, no clinical pharmacokinetic data and no long term toxicology in the peer reviewed record.

Selling or advertising any of them for human use would make them unlicensed medicines under MHRA rules, which is why this listing carries no usage guidance.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eHow fast is delivery?\u003c\/strong\u003e Orders placed before the daily cut off are despatched the same working day by tracked delivery, with UK orders usually arriving within two to three working days and a next day upgrade available at checkout. Everything leaves in plain outer packaging with no reference to the contents or to the compound on the outside of the parcel. International delivery is available to most countries, although some destinations are restricted because of local customs rules, and restricted countries are listed at checkout.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eHow should the capsules be stored?\u003c\/strong\u003e Keep the bottle sealed in a cool, dry place below 25C and out of direct sunlight. Stored that way the capsules remain stable for the shelf life printed on the label. Avoid humid environments such as bathrooms and kitchens, because moisture is the main cause of degradation in capsule form.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eAre these compounds banned in sport?\u003c\/strong\u003e Yes, all of them, at all times. The SARMs fall under section S1.2 of the WADA prohibited list, MK-677 under section S2 as a growth hormone secretagogue, and cardarine and SR-9009 under section S4.5 as metabolic modulators. Detection methods exist for each.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eHow do these two compounds differ from each other?\u003c\/strong\u003e LGD-4033 has a published human phase I study with measured lean mass and hormonal endpoints. RAD-140 has a stronger preclinical package, including primate work, but no published human efficacy trial. Both are non steroidal androgen receptor ligands and both suppress endogenous hormone production in the studies where that was measured. The practical difference is the depth of evidence rather than any claim about relative strength.\u003c\/p\u003e \u003cp\u003e\u003cem\u003eResearch use only.
