GHK-Cu lot was outstanding
We use GHK-Cu in dermal fibroblast research. This lot performed exactly as expected — >98% purity HPLC. The COA cited the reference standard lot number. That detail is rare at this price point.
NAD+ (Nicotinamide Adenine Dinucleotide) is a fundamental coenzyme involved in over 500 enzymatic reactions including redox metabolism, sirtuin activation, and PARP-mediated DNA repair. Circulating NAD+ levels decline with age, driving interest in cellular senescence and longevity research.

NAD+ (Nicotinamide Adenine Dinucleotide) is a dinucleotide coenzyme present in all living cells. It serves as both an electron carrier in metabolic redox reactions and a substrate for NAD+-consuming enzymes including sirtuins (SIRT1-7), PARPs, and CD38. NAD+ levels decline approximately 50% between ages 40-60 in human tissue samples.
NAD+ is studied in ageing biology, neurodegeneration, metabolic disease, cardiovascular disease, and DNA repair. Preclinical NMN/NR supplementation studies have driven interest in NAD+ restoration as an ageing intervention. Clinical trials in humans are ongoing.
For Research Use Only. Rainbow Peptide supplies NAD+ exclusively for in vitro and laboratory research purposes. Not for human or veterinary use.
Third-Party Verified
We don't just claim purity — we prove it. Every batch of NAD+ is independently tested by an accredited third-party laboratory before it reaches you. Your COA is linked to your specific lot number.

Sourced Epithalon from three vendors this quarter. Rainbow Peptide had the most detailed COA and lowest endotoxin levels measured. Will be primary source for our current project.
GHK-Cu arrived in 2 business days. Cold pack still active on delivery. Peptide dissolved cleanly in bacteriostatic water. COA was comprehensive. Happy with this purchase.
