BPC-157GHK-Cu

The two leading regenerative peptides, but for different tissues. BPC-157 acts at the vascular and motile tissue level (tendons, GI tract, nerves). GHK-Cu acts at the matrix level — skin, fasciae, hair, wound healing.

Spec	A BPC-157	B GHK-Cu
Primary mechanism	Angiogenesis via VEGFR2 + NO	Collagen synthesis + Cu²⁺ delivery
Primary tissue	Tendons, GI tract, nerves, joints	Skin, fasciae, hair
Length	15 AA	3 AA (tripeptide)
Origin	Gastric juice (Sikiric, Zagreb)	Natural plasma tripeptide (Pickart)
Age-related decline	Not applicable (synthetic)	Yes — 60% decline age 20 to 60
Administration	s.c. daily or oral	Topical 0.05-0.2% or s.c.
Gastric stability	Yes	Not systemically
Gene regulation	Not described in literature	Modulates 4000+ genes (31% of the genome)

Choose A when

BPC-157

Tendon/joint recovery, GI regeneration, nerve injury. Oral option is a plus.

Choose B when

GHK-Cu

Skin regeneration, anti-aging, wound healing, hair loss. Strong antioxidant activity.

Verdict

Different mechanisms for different tissues. Often combined in recovery protocols — BPC drives vasculature, GHK-Cu builds matrix. Together they cover the full regenerative cycle.
