Studio Peptide + PDRN Booster · GHK-Cu
Our studio-strength GHK-Cu, now co-formulated with salmon-derived PDRN at a balanced 2.5 mg/mL — the signalling peptide and the regenerative nucleotide held together in a single sterile single-dose vial. The firming arc and the repair arc, finally in one pour. Reserved for the slow remodelling work: the orbital ridge, the jawline, the long return after a heat-based session.

How it works.
GHK-Cu floods the receptor pathway your fibroblasts have always used — procollagen climbs, elastin remodelling follows. PDRN works in parallel along the salvage pathway, supplying the nucleotides that same repair work depends on. Together: the signal and the substrate, in one quiet pour. Suited to the firming arc, and to the long return after radiofrequency or fractional heat.
Part of the Junsui Clinic Extensions collection. The professional side of the ritual — the tri-pin microneedling systems, sterile glide vials and studio-strength concentrates kept behind a small application. Designed for licensed practitioners; available, under guidance, to advanced home users who have completed our written safety protocol. For topical and micro-channel use only — never for injection.
