What is GHK Basic (Tripeptide-1)?
—also known as ****—is a naturally occurring peptide made of three amino acids: glycine, histidine, and lysine.
It’s found in:
- Human plasma
- Saliva
- Skin tissue
It plays a role in cell signaling related to tissue repair and skin maintenance.
What “50mg vial” usually means
A listing like:
👉 GHK Basic 50mg
typically refers to:
- A freeze-dried (lyophilized) peptide powder
- 50 milligrams total content
- Intended for research or formulation use (often skincare R&D)
- Not a finished cosmetic or medicine
These products are commonly labeled:
“For laboratory research or cosmetic formulation use only”
What it’s studied for
In research and cosmetic science contexts, GHK is associated with:
Skin biology
- Collagen production signaling
- Skin remodeling and repair pathways
- Extracellular matrix regulation
Wound and tissue response
- Cellular repair signaling
- Anti-inflammatory gene expression modulation
Related form: GHK-Cu
It is closely related to (copper peptide), which is more widely studied in skincare research.
Important reality check
Even though it’s widely marketed online:
- ❌ Not FDA-approved as a drug
- ❌ Not a standardized cosmetic active at raw powder form
- ❌ No regulated dosing for human use
- ✔ Classified as a research / cosmetic ingredient
Why it’s popular
It shows up in:
- Anti-aging skincare discussions
- “Peptide serum” DIY formulations
- Cosmetic R&D ingredient lists
- Biohacking skincare communities
But the actual effectiveness depends heavily on formulation stability, delivery system, and concentration, not just raw peptide weight.
Key takeaway
() is a naturally occurring skin-relevant signaling peptide studied for repair and collagen-related pathways, but “50mg vial” products are unregulated raw materials—not finished skincare or approved medical products.
