About SARMs

What they are: Selective androgen receptor modulators — oral compounds designed to hit muscle and bone androgen receptors while sparing prostate and skin. None is an approved medicine anywhere.
How they're run: Taken orally once a day, typically in 8–12 week blocks.
What to watch: The "non-suppressive" reputation is marketing: most suppress natural testosterone, and several are liver-toxic. Independent testing repeatedly finds products containing something other than the label. Bloodwork before and after is the minimum.
