What is GHK Basic (Tripeptide-1)?

is a naturally occurring tripeptide (Glycine–Histidine–Lysine) found in human plasma, saliva, and tissue fluids.

It is also closely related to the better-known form:

• (copper-bound version)

In research, it’s studied mainly for:

• Skin repair signaling
• Collagen and extracellular matrix regulation
• Wound-healing and cellular stress response pathways

What “200mg topical” means

A listing like:

👉 GHK Basic 200mg (Tripeptide-1) topical

usually refers to:

• 200mg of freeze-dried peptide powder
• Intended to be mixed into topical formulations (serums/creams)
• Not a finished cosmetic product
• Sold as research-use material

Example listings describe it as a lyophilized tripeptide used for skincare research and extracellular matrix studies (Peptides Sciences Store).

Why it’s popular in skincare research

In lab and cosmetic research contexts, GHK is studied for:

• Supporting collagen production pathways
• Influencing skin remodeling signals
• Antioxidant and wound-response gene activity
• Interaction with copper ions (in GHK-Cu form)

Because of this, it’s often marketed in “anti-aging” or “skin regeneration” product categories—even though those claims vary widely in strength.

Important reality check

Even though it’s widely sold online:

• ❌ Not FDA-approved as a drug
• ❌ Not a regulated cosmetic active at these concentrations
• ❌ No standardized human dosing for peptide powders
• ✔ Classified as research chemical / cosmetic research ingredient

Most vendors clearly label it:

“For laboratory or topical research use only, not for human consumption” (Core Peptides)

---

Why confusion happens

Products like this are often grouped with:

• Cosmetic peptides (anti-aging skincare ingredients)
• Research peptides (lab-only materials)
• “Bioactive skincare actives” marketed online

So the same molecule can appear in:

• Scientific research catalogs
• DIY skincare forums
• Unregulated “cosmetic peptide” shops

---

Key takeaway

() is a naturally occurring skin-related signaling peptide studied for collagen and tissue repair pathways, but “200mg topical” products sold online are unregulated research materials—not standardized or approved skincare treatments.
