GHK-Cu 50mg
GHK-Cu is a copper-binding peptide used mainly for skin quality, tissue repair, hair support and recovery. It is naturally related to the GHK peptide found in the human body and has been studied extensively for collagen production, skin remodeling and wound-repair processes.
Thai Anabolics supplies Cat Pharmaceuticals GHK-Cu in a 50mg vial. The vial is supplied as freeze-dried powder and can be mixed to suit the daily dose you want to use.

Dosage guide
GHK-Cu Dosage
| Goal | Daily Dose | Typical Duration |
|---|---|---|
| Skin / Anti-Aging | 1–2mg per day | 8–12 weeks |
| Hair Support | 2mg per day | 16–24 weeks |
| Tissue / Wound Recovery | 2–3mg per day | 4–8 weeks |
| General Recovery | 0.5–1.5mg per day | 30 days on / off |
| Acute Injury Support | 1.5–2.5mg per day | 10–14 days |
For skin and general recovery, 1–2mg per day is the easiest range to work with. Higher daily amounts are normally reserved for shorter recovery-focused use.
Mixing guide
How to Mix a 50mg GHK-Cu Vial
A simple option is to add 5ml of sterile water to the 50mg vial. This gives a concentration of 10mg/ml and keeps the daily syringe measurements easy.
Using a U-100 insulin syringe, 100 units = 1ml.
| GHK-Cu Dose | U-100 Syringe |
|---|---|
| 0.5mg | 5 units |
| 1mg | 10 units |
| 1.5mg | 15 units |
| 2mg | 20 units |
| 2.5mg | 25 units |
| 3mg | 30 units |

Skin & collagen
Why GHK-Cu Is Used for Skin Quality
GHK-Cu has been studied for its effects on collagen, elastin, skin thickness, firmness and tissue remodeling. Human topical studies and laboratory research have reported improvements in several measures of aging skin.[1]
This is why GHK-Cu is commonly chosen by clients focused on skin quality and anti-aging rather than muscle gain or fat loss.
Repair & recovery
GHK-Cu for Tissue Repair
GHK-Cu is also widely studied for wound repair, fibroblast activity, collagen formation and tissue remodeling. A large amount of the repair data comes from cell and animal research, with additional human skin studies supporting its cosmetic use.[2]
For this reason, GHK-Cu is often used as part of a broader recovery-peptide setup.
Recovery combinations
Peptides Commonly Used With GHK-Cu
GHK-Cu is most often paired with other recovery peptides when the goal is to cover skin, connective tissue and general recovery at the same time.
| Goal | Peptide Combination |
|---|---|
| Skin + Recovery | GHK-Cu + BPC-157 |
| Connective Tissue | GHK-Cu + TB-500 |
| Full Recovery Stack | GHK-Cu + BPC-157 + TB-500 |
GHK-Cu handles the skin/remodeling side of the stack, while BPC-157 and TB-500 are normally added when deeper tissue and physical recovery are also priorities.
Hair support
GHK-Cu and Hair Growth
GHK-Cu is also used in hair-focused products because copper peptides have been studied for effects on hair follicles, tissue remodeling and the skin environment around the follicle.[1]
For clients using GHK-Cu mainly for hair support, 2mg per day is the practical dose shown in our current protocol, normally used for a longer 16–24 week period.
