CU50 GHK-Cu (Copper Tripeptide-1): High Purity Copper Peptide for Skin & Tissue Repair Research

Product Overview

CU50 is lab-grade GHK-Cu copper tripeptide lyophilized powder, designed for cosmetic biochemistry, tissue regeneration, anti-inflammation and skin repair research. It delivers HPLC-verified purity ≥99%, with a natural mild pH range of 5.0–7.0 that matches common cell and skin culture media.
Two standard bulk sizes are available: 50mg10 vials and 100mg10 vials. The distinctive deep blue powder makes identification simple during lab preparation, and it is exclusively manufactured for laboratory research use only.

Core Advantages for Research Laboratories

1. ≥99% High Purity Eliminates Assay Interference

Many low-grade GHK-Cu on the market contains heavy metal impurities and incomplete peptide fragments, which create unstable results in collagen synthesis and anti-inflammatory cell tests. Every CU50 batch undergoes strict independent HPLC testing. Researchers can receive full certified purity reports for every single vial to meet university audit and academic paper submission standards, skipping extra purification control trials.

2. Neutral pH Matches Skin & Cell Culture Conditions

Its natural 5.0–7.0 pH range aligns closely with human skin cell fluid and standard serum-free culture media. No extra acid or alkaline buffer adjustment is needed before mixing, cutting daily lab pre-test preparation time significantly. The lyophilized deep blue powder dissolves completely with gentle swirling, leaving nearly no residue on vial glass walls for accurate low-dose testing.

3. Two Flexible Vial Sizes Fit All Trial Stages

The 50mg vial is perfect for small preliminary screening, cosmetic formulation simulation and low-concentration cell culture testing. The 100mg bulk option supports large-scale tissue regeneration rodent trials and long-term dose-response comparative research. Both sizes deliver identical peptide potency, so researchers can switch packs without recalibrating testing equipment.

4. Stable Frozen Storage Preserves Full Bioactivity

When sealed in opaque freezer bins at constant -20°C away from light, unopened CU50 vials retain complete collagen-boosting and anti-inflammatory activity for multiple months. Long-term exposure to room light or repeated freeze-thaw cycles will fade the blue powder color and weaken its tissue repair effects. The airtight blue flip cap blocks moisture intrusion even after dozens of needle punctures for partial sampling.

5. Shockproof Secure International Shipping

Each bulk kit uses custom foam dividers to separate every glass vial individually during cross-border delivery. Over thousands of global orders, zero vials arrive cracked, leaking or contaminated. Insulated packaging maintains stable low transit temperatures to prevent premature peptide degradation during long-distance shipping.

Main Research Application Scenarios

1. In-vitro skin fibroblast cell culture for collagen & elastin synthesis testing
2. Rodent wound healing and soft tissue regeneration comparative trials
3. Cosmetic raw material anti-aging, anti-redness and antioxidant mechanism research
4. Dose-response assays for copper peptide anti-inflammatory pathways
5. Dermatology lab studies on skin barrier repair and oxidative stress relief

Real Verified Lab User Feedback

I run skin cell repair experiments for cosmetic research, CU50’s consistent high purity makes my collagen test data super stable. The blue powder dissolves cleanly without leftover residue, and the neutral pH works perfectly with my skin cell media. I store all vials frozen away from light to keep full activity long-term.
— Rowan, Cosmetic Biochemistry Research Lab

I regularly order the 50mg 10-vial pack for small pilot tests, and switch to 100mg batches for full wound recovery mouse trials. Support can send individual HPLC certificates for each vial within 24 hours, which satisfies my school’s strict research audit rules. Cross-batch potency is totally uniform every restock.

Critical Storage & Operation Guidelines

1. Keep all unopened sealed vials in fully opaque freezer boxes at steady -20°C; avoid direct lab UV light exposure, which discolors powder and lowers its repair function.
2. Reconstitute powder only with slow circular swirling; vigorous shaking damages peptide chains and ruins cell assay accuracy.
3. After reconstitution, store diluted working liquid in the fridge and finish all testing within 4–6 days; discard faded, cloudy blue liquid to guarantee reliable trial data.
4. Minimize repeated freeze-thaw cycles for partially used vials; frequent temperature fluctuations break down the copper tripeptide structure and reduce biological performance.

Final Conclusion

CU50 GHK-Cu copper tripeptide is a reliable single-source peptide for labs focused on skin repair, tissue regeneration and cosmetic anti-aging research. Its certified ≥99% HPLC purity, neutral skin-friendly pH, dual flexible packaging sizes and consistent cross-batch potency solve the most common pain points researchers face with generic low-quality copper peptide products. Whether you carry out small-scale cell screening or long-cycle in-vivo wound healing animal trials, CU50 delivers repeatable, publishable experimental results while cutting raw material waste and daily lab preparation workload.
