Yup, and I don't dare do IV on myself. Easy enough to do with a butterfly needle but I've never been able to do venipuncture on myself lol I'd likely pass out
I was literally just experimenting. I figured every time I upped the dose I didn't get any sides and heard people were doing up to 10mg/day so just kept going up. Eventually I did notice I got palpitations which I'm assuming was my blood pressure going lower from both reta and ghkcu
I will say though that ghkcu for sure has some systemic benefits. I swear it healed my lungs because I started ghkcu and felt like things were changing in my air way then started running again and ran a sub-6min km right off the bat
Btw, this is totally anecdotal but I used to do a shot of half a lemon juice and half tsp of matcha in the morning and that literally evened out my skin tone
