BPC-157 vs GHK-Cu
BPC-157 vs GHK-Cu: tendon and tissue healing vs collagen and skin support. Which to pick or whether to stack.
The verdict
Different targets entirely. BPC-157 is the tendon, ligament, and gut-repair peptide; GHK-Cu is the collagen, skin, and hair-follicle one. If your problem is a stubborn joint or gut issue, BPC-157 is the pick. If it's skin quality, scarring, or hair, GHK-Cu is. Plenty of people run both, often in a healing-plus-skin stack like GLOW, because the jobs barely overlap and the combination covers more ground than either alone.
Think of BPC-157 as a healing accelerator for connective tissue. Most users run it for stubborn tendon, ligament, or gut problems where regular rehab has stalled. You inject a tiny amount under the skin once a day for 4-6 weeks, take a break, then reassess.
GHK-Cu is a tiny copper-binding peptide your skin already has, but levels drop with age. Used to support collagen, wound healing, and hair follicles. Topical for skin, sub-q injection for systemic effect on connective tissue.
Which one should you pick?
Pick BPC-157 if lifters with nagging tendon or joint pain or anyone recovering from a soft-tissue injury.
Pick GHK-Cu if anyone running an aggressive skin/anti-aging routine or healing stack add-on for connective tissue.
Note: these two are commonly stacked together rather than chosen between. See the entries for the canonical protocol.
