@NocturnalNelly@AntiDoc I do both, injections and use topical while using a microneedle pen. The results have been amazing in only 6 six weeks. Use with Ahk-cu for better results.
@doubleJ200 Sad thing is the "super premium" get it from the same manufacturers as the Chinese middle-men. I have a source that provides to the major sellers in the US who proved evidence to this fact. Especially raw peptide powders.
