Is your friend saying a doc is prescribing peptides?
Stick to the basics bro of a ghrp and GHRH combo. Currently I'm researching with ghrp2 and cjc-1295 no dac/mod grf 1-29. Check out Labpe Peptides sub forum for many past and current logs on their peptides. Quality I assure you is there.
Dosing would have to go along with goals with research. What are you thinking?
