Long post, sorry. Thymosin beta-4 (TB-500): what actually has human evidence behind it, and what is extrapolation from animals?
Tolerance and underdosing look identical from the inside, which is why the answer is usually a blood test and not more forums.
Forum consensus and published consensus diverged here about five years ago and never reconverged.
Sample size, blinding, and who paid for it. Those three questions kill most of the confidence in most of these threads.
Vial content, sterility and reconstitution are three separate questions and the certificate answers about one of them.
Willing to accept that my own experience is the weakest evidence in the room.
Narrow conclusion.
Baseline first.
Is a baseline blood test really necessary before starting something like this?
