How it works

The copper and the peptide together stimulate collagen production and skin repair.

Most reported

• Firmer, better-looking skin
• Better wound healing
• Hair support

Evidence level

Good data via topical use (creams); the injectable route is less studied.

Common side effects

Injection-site reaction; copper accumulates, which is why it is cycled.

Combines / avoids

It's the base of the GLOW and KLOW blends.

Typical use

~5 days a week, dose of 1-2 mg, in cycles.

How it works

Combines collagen and skin support (GHK-Cu) with tissue repair (BPC-157 + TB-500).

Most reported

• More radiant skin ("glow" effect)
• Overall recovery

Evidence level

No human studies of the blend as a whole.

Common side effects

Those of its three components; injection-site reaction.

Combines / avoids

It's a blend; avoid duplicating GHK-Cu, BPC-157, or TB-500 separately.

Typical use

Fixed daily dose (~2.3 mg), in 4-week cycles.

How it works

Adds KPV's anti-inflammatory effect on top of the GLOW trio.

Most reported

• Skin and recovery, plus KPV's anti-inflammatory support

Evidence level

No human studies of the blend as a whole.

Common side effects

Those of its four components; injection-site reaction.

Combines / avoids

It's a blend; cycled because of the copper in GHK-Cu.

Typical use

Fixed daily dose (~2.7 mg), in 4-6 week cycles.
