Customer Reviews
Наталья К. — ★★★★★
Skin, nails, hair — all improved after three months on ghk-cu. The gene expression modulation affects tissues system-wide. That's the advantage of subcutaneous injection over topical-only application. Peptex quality is consistently excellent.
Lotte_nl — ★★★★★
Good product. Expected more dramatic results based on what I read, but the improvements are real, just gradual. Skin does feel firmer, small cuts heal faster. More of a long-term investment than a quick fix.
Filippo — ★★★★★
On my fourth vial. At 1mg/day subQ, a 50mg vial lasts almost two months. That's excellent value. The effects on skin firmness and overall tissue quality are cumulative over cycles. Peptex consistency is why I stick with them.
Bram87 — ★★★★★
Using GHK-Cu both subcutaneously and topically (mixed into my serum). The injectable provides systemic gene expression effects. The topical targets my face specifically. Peptex quality dissolves perfectly for both applications. 50mg vial lasts ages.
Matteo R. — ★★★★★
Combined GHK-Cu with my microneedling sessions. The recovery time was cut in half and the collagen induction results were significantly better according to my esthetician. Peptex quality makes a difference in sensitive applications like this.
