I started ghkcu in January at 3mg then went up to 15mg at this point. Widow's peak is starting to come back, body hair is noticeably longer, idk if related but my 5km pace improved, feels like I can take in more oxygen per breath or whatever
I'm on topical fin/min already 😅 I'm watching carefully for sides and also taking zinc. I'm literally researching with this stuff at this dose but I've seen posts on Reddit of people doing 20mg+
