I'm looking to take cjc 1295 + ipamorelin, bpc-157 + TB-500, GHK-Cu,
and I'm looking to gain muscle, recover faster, and improve my skin. I'm a bit unsure about GHK-Cu, since I heard that collagen is at its peak and for me at 18 (almost 19) it might be unnecessary. Will it still have benefits? Also is a copper and zinc capsule a good/better option?
