I think if you have the disposable income for testing it is a no brainer, does not reduce the risk to zero, but a lot. I think buying from random tiktok sellers likely has pretty high rates of no drug inside, there are papers showing this. But the sellers on here I think are less likely to do that as they will get found out fairly reliably. Getting no drug is not ideal, but getting the wrong one could be a serious problem, but I do not really see a good motivation for sellers to do this, if you want to rip customers off, just send nothing and keep the money, then send vials with no drug, sending the wrong ones makes the least sense.
I figure my risks of dying or serious illness from putting back on a pile of weight is at least 10-40% over the next decade, so risks from grey peptides causing similar levels of damage are at worst an order of magnitude or more likely 100 x lower or better than putting lots of weight back on, and I cannot afford the original versions. If taking them drops these risks by a factor of 2 to 5 then I am happy enough to accept those extra risks from grey peptides.
Getting very specific dose dependent side effects from tirz like tinnitus getting louder and patchy skin sensitivity from either reta or tirz makes it super easy to tell the drug is in the vial.
