Thirty-eight hands say yes, fourteen say no, and 143 people never answer at all. The silence is the biggest thing in the room. Here is the catch: the people who felt nothing do not raise a hand, and they do not write a post e https://zyratrack.com/media/ss-8-silences-ea384e34.mp4 The SS-31 trial ran 24 weeks. Nobody in our log got past 12. (9/10) https://zyratrack.com/media/ss-9-duration-poster.jpg Think of the trial as a marathon: 24 weeks of daily injections. Of the 52 reports that say how long they ran it, 45 stopped inside six weeks; the typical run is about a month; the longest anyone describes is 12 weeks — half the distance of the trial that missed. The run that earned the approval, in https://zyratrack.com/media/ss-9-duration-938a7927.mp4 What 197 SS-31 reports cannot tell you (10/10) https://zyratrack.com/media/ss-10-ledger-poster.jpg Our log as a receipt: 197 lines, with whole columns torn off. Nobody’s purchase is verified, no vial was tested, nothing was weighed, and one in five of these people name another compound in the same breath — so even a clear win could not be pinned on this one.

Its inventors wrote that it "lacks oral bioavailability"; in our log, of the 216 reports we hold, 101 name a route and 78 of those describe swallowing it. Nine chapters: what the compound is, the oral contradiction, a community split 100-to-112 on w https://zyratrack.com/media/slu-film-5b8ca11a.mp4 SLU-PP-332: the exercise pill that only worked in mice (1/9) https://zyratrack.com/media/slu-1-pill-poster.jpg SLU-PP-332 is sold as “exercise in a pill”. It is a synthetic pan-agonist of the ERR nuclear receptors — the switches muscle uses to build mitochondria and burn fat. In mice it worked: they ran farther and longer, muscle shifted toward endurance fibres, fat fell.

Half in milligrams. Same compound.

That is not a titration preference — it is a thousandfold disagreement about what kind of compound this is.

Resist the obvious reading of 52-to-7: an uncontrolled, self-selected, publicly posted sample produces flattering ratios for essentially any in https://zyratrack.com/media/slu-4-said-0856c09f.mp4 The side effect people describe most: they run hot (5/9) https://zyratrack.com/media/slu-5-hot-poster.jpg Fifteen of the 216 SLU-PP-332 reports we hold describe something adverse. That is a count from a self-selected public log, not an incidence rate — nobody here was followed up and under-reporting of harm is the expected bias.

They characterise the compound and its successor in vitro so a doping-control test knows what to look for.
