I do not think a single tesamorelin study settles anything, but the aggregate is more interesting than any individual paper. Tolerance and underdosing look identical from the inside, which is why the answer is usually a blood test and not more forums.
Stupid question: how do you know whether what is in the vial matches the label at all?
Narrow conclusion.
Read methods.
Baseline first. Currently on tesamorelin myself.
How long before you can reasonably say something is or is not doing anything? How long have you been on tesamorelin?
My rule, after years of this: if it cannot survive being written down with the numbers attached, it is marketing.
Loose evidence is not nothing, but a washout either side is the only reason to trust your own take.
