Long post, sorry. Thymosin beta-4 (TB-500): what actually has human evidence behind it, and what is extrapolation from animals?
The effect size I actually noticed is roughly a third of what the write-ups imply, and it took three years to be sure.
What surprised me is how much of the perceived benefit was routine and attention rather than pharmacology.
Two weeks is not enough time to attribute anything to a compound unless the effect is dramatic.
Forum consensus and published consensus diverged here about five years ago and never reconverged.
Willing to accept that my own experience is the weakest evidence in the room.
Nobody has ever been talked out of a stack by a stranger on the internet.
Narrow conclusion.
Sterility is the part people wave through and it is the part that actually bites. Injection site reaction was my main issue with TB-500 too.
Stupid question: how do you know whether what is in the vial matches the label at all?
Same here.
