Its main published placebo-controlled human study, a 21-day trial in 76 healthy men aged 21 to 50, reported dose-dependent gains in lean body mass with no significant change in fat mass, together with dose-dependent suppression of total testosterone, SHBG, HDL cholesterol and triglycerides, which returned to baseline after the study ended (Basaria 2013).

It has more human trial data than most compounds in this category. A two-year randomised trial in 65 healthy adults aged 60 to 81 reported, at its one-year primary analysis, sustained rises in growth hormone and IGF-1, about 1 kg more fat-free mass than placebo and no gain in strength or function, alongside increased appetite, mild fluid retention, muscle pain, higher fasting glucose and reduced insulin sensitivity (Nass 2008).

Ibutamoren, ligandrol and ostarine headed the list of the five molecules reported most often, and about a quarter of products had been presented as dietary supplements, which the authors noted leaves buyers unaware that a pharmaceutical substance is inside.\u003c\/p\u003e\n\u003cp\u003eLabels are the other problem. Of 44 products bought online as SARMs in 2016, only 23 contained a SARM at all, while 17 held a different unapproved drug, ibutamoren among them, and only 18 matched the amount on their label (Van Wagoner 2017).

No study has compared formats for any of them, so the useful comparison concerns measurement, not effect.\u003c\/p\u003e\n\u003cp\u003eA capsule fixes its quantity once, at filling, before the container is sealed. A laboratory can then report milligrams per capsule directly. The weakness is variation between capsules, which depends on how evenly the powder was mixed and which a single averaged assay cannot show. A liquid fixes only a concentration. Every later portion depends on the measuring device and on solvent not evaporating from a bottle opened many times. Loose powder fixes nothing in advance and relies wholly on the balance used to weigh it.\u003c\/p\u003e\n\u003cp\u003eAll three are small synthetic molecules, not peptides, so the argument that swallowed peptides are largely digested, discussed in \u003ca href=\"\/blogs\/news\/do-oral-peptides-work\"\u003edo oral peptides work\u003c\/a\u003e, does not apply in the same way; each trial cited above gave the compound by mouth.
