Prendre un Sarm dont l'efficacité est douteuse alors qu'un gramme de testo / semaine = t'explose 
As many of you know, RAD140 was trialed in Phase 2 in humans in 2018-2020. The initial results were reviewed by MPMD and others and were interesting in at least the high dosing of RAD140 that the trial subjects took.
Now the full results of this last human clinical trial of RAD140, which completed in 2020, were published just very recently, few weeks ago. See: https://www.sciencedirect.com/science/article/abs/pii/S1526820921002408
Full paper contains some very interesting takeaways:
The researchers conclude that 100mg daily dose has had acceptable safety profile, and warrant further clinical trials (it seems to be working against cancer);
RAD140 half-life was established at ~44.7 hours;
RAD shows variable oral absorption ranging from 6 to 71 hours, suggesting that individual responses may vary;
Main side effect reported was ALT/AST elevation (they mention that the same was observed for lower dose (9/18mg trial) Enobosarm and cite the yet unpublished Enobosarm Phase 2 trial paper; BUT
The researchers argue that the elevation of transaminases is due to “androgenic effect related to increased enzyme synthesis in hepatic and non hepatic tissues (there are androgen response elements present on the ALT and AST genes). This could explain the high frequency of elevated transaminazes in the absence of evidence of hepatic toxicity.” This basically claims that ALT/AST elevation by SARMs may be benign and does not indicate liver toxicity, also in both Enobosarm and RAD140 trials the elevation is said to be transient and normalizes after stoping the compound;
Whether it is liver toxic or not, it may be worthwhile to note that 18mg of Enobosarm may on average have the same (or higher ?) impact on the liver as 100mg of RAD140, although in current broscience Enobosarm (Ostarine) is thought to be somewhat milder on the organs (hair is another story), and because of it Osta is commonly cycled at 25mg/day (higher than in clinical trials), while RAD at 10-20mg/day (much lower than clinical trials).
I am not advocating anyone to shoot for 100mg/day RAD140 cycle, especially since we know that it has some other side effects on hair, mood, sleep, etc., but it may be rather encouraging that it does not require a liver transplant even at this high dosing.
