Research-Grade Peptide Therapeutics
Cellular science,
engineered for renewal.
ASR Labs formulates and batch-tests copper peptide compounds for skin, hair, and cellular repair research — beginning with our flagship compound, GHK-Cu.
In brief
One copper ion. Three amino acids. A signal the body already knows.
The molecule
A naturally occurring copper peptide, refined for the lab.
GHK-Cu — Glycyl-L-Histidyl-L-Lysine bound to a copper (II) ion — occurs naturally in human plasma and declines steadily with age. Research since the 1970s has linked the compound to collagen and elastin synthesis, antioxidant signaling, and tissue remodeling pathways.

Flagship compound
GHK-Cu, dosed for precision.
Every pen ships pre-filled and cold-chain verified, with a calibrated dose counter for exact, repeatable dosing across a full research protocol.
Skin
Collagen & elastin signaling
Hair
Follicle density research
Nails
Keratin structure support
Cellular
DNA repair pathways
Compounding
Filled and sealed under robotic precision.
Every pen is compounded, filled, and capped in a cGMP-aligned facility, with automated handling minimizing contact and variance between doses.
Protocol
Six steps, the same way, every time.
Every pen ships with a full illustrated guide. Consistency in administration is what makes a research protocol repeatable.
Attach a sterile needle
Remove the pen cap and thread a fresh needle until fully seated.
Prime the pen
Remove both needle caps and dial to prime, purging air from the line.
Set the dose
Turn the counter to your protocol's measured dose.
Administer
Pinch the site, insert, and hold until the counter reaches zero.
Withdraw & log
Hold for 5–10 seconds, withdraw, and record the dose administered.
Dispose safely
Recap and remove the needle into an approved sharps container.
Quality
Every batch is tested, logged, and shipped cold — nothing else asked of it.
The complete kit
Everything arrives ready to log.
The full protocol case — pen, needle stock, and a printed instruction guide — ships sealed and cold-chain verified in a single box.
