Skin Glow

GHK-Cu (glycyl-L-histidyl-L-lysine-copper) stimulates collagen and elastin synthesis, activates antioxidant protection, accelerates skin regeneration and healing. The rejuvenation effect is supported by clinical studies of topical forms (creams, 12 weeks); the injectable form is research-grade.

DOZA clients note skin tightening, wrinkle reduction and texture improvement after 4–6 weeks of course. Visible effect — radiance and firmness. These are self-reported client impressions, not results of a clinical trial.

Standard manufacturer protocol: 7 clicks (2.33 mg) daily subcutaneously, cycle 15 days on / 15 days off (1 cycle per month). Set pen dial to '7' (1 division = 1 click, 1 click = 333 μg). Alternatively — daily dosing 1–2 mg for prolonged anti-aging cosmetic protocols. 1 pen 100 mg lasts 2–3 months. Full course — 2 pens (4–6 months). DOZA consultant will select regimen for your needs.

Yes, GHK-Cu is often combined with BPC-157 (regeneration), PT-141 and NAD+. DOZA develops personalized stacks for comprehensive rejuvenation.

According to topical clinical studies, GHK-Cu is well tolerated; the full safety profile of the injectable form in humans has not been separately established. Not recommended during pregnancy without consultation. DOZA conducts individual analysis before course.

Store at 2–8°C in refrigerator. Thanks to MSSPT technology (Molecular Structure Stabilization Process Technology) formula is stabilized and tolerant to short-term temperature deviations above 8°C during delivery. DOZA delivers pens in thermal box with cold chain — from warehouse to your door.

Set pen dial to '7' (standard dose 7 clicks = 2.33 mg). Make subcutaneous injection into abdomen or front of thigh. After injection, wait 10 seconds before withdrawing needle. Rotate injection sites to avoid induration. 1 pen contains 300 clicks (100 mg).

GHK-Cu is a tripeptide complex of glycine, L-histidine and L-lysine bound with copper ion (Cu²⁺). Pen Peptide supplies it in stabilized pre-mixed form: 100 mg GHK-Cu (300 clicks), purity ≥98%. Synthesis — in certified GMP laboratories using MSSPT technology, which preserves molecule bioactivity throughout storage period.

A lyophilized vial is a powder that must be reconstituted with bacteriostatic water before use, with the dose drawn manually using an insulin syringe. The Pen Peptide pre-filled pen is a ready stabilized solution: no reconstitution, the dose is measured by dial clicks (1 click = 333 mcg, standard dose 7 clicks = 2.33 mg), a closed sterile system without repeated cap punctures. Vials are usually cheaper but require experience, extra consumables, and precision when reconstituting and storing the prepared solution. For home use without medical experience, the pen is the more practical and safer format.

The pen price includes a finished sterile form: factory reconstitution and solution stabilization (MSSPT technology), a precise dose dial (300 clicks × 333 mcg), a closed system without repeated punctures, and a 2–8°C cold chain. A powder vial is cheaper because reconstitution, syringes, and responsibility for dose accuracy fall on the user. At DOZA, the original Pen Peptide Skin Glow 100 mg pen costs ₴3,500 — enough for 2–3 months of the protocol with a free specialist consultation.

Human clinical studies of GHK-Cu were conducted specifically on topical forms: creams improved skin firmness and density and reduced wrinkles in 12-week studies. The problem with creams is that the molecule penetrates only the upper skin layers. Subcutaneous injections deliver GHK-Cu systemically, bypassing the stratum corneum barrier — but there are no controlled human clinical trials of the injectable form yet; it is a research-grade format. A DOZA specialist consultation is required before starting the course.

Yes. Skin Glow is the trade name of the Pen Peptide pre-filled pen whose active substance is GHK-Cu (copper peptide, copper tripeptide-1, glycyl-L-histidyl-L-lysine copper). One Skin Glow pen contains 100 mg of GHK-Cu with ≥98% purity in a stabilized pre-mixed form. So "buy skin glow" and "buy ghk-cu pen" refer to the same product.

No, GHK-Cu is not FDA approved as a drug. As of August 2026: in April 2026 the FDA removed GHK-Cu from Category 1 of the 503A list (due to nomination withdrawals), and on May 14, 2026 restored only non-injectable forms to Category 1 — injectable GHK-Cu remains outside Category 1. The PCAC advisory committee will review GHK-Cu by the end of February 2027. In Ukraine, GHK-Cu is not registered as a medicinal product; Skin Glow is research-grade, so a specialist consultation is required before use.
