The Researcher's Guide to Peptides: Which Compound Is Right for Your Study?

Whether you're investigating tissue repair, metabolic signaling, or cellular longevity, choosing the right research peptide is critical to the integrity of your study. At Star Valley Peptides, we supply ISO-manufactured, HPLC-verified compounds at ≥99% purity — each shipped with a Certificate of Analysis so your protocols stay reproducible and reliable.

Here's a breakdown of the most studied peptide categories and the compounds we carry for each research application.

🔬 Tissue Repair & Regeneration

BPC-157 remains one of the most widely referenced peptides in preclinical tissue-repair research. Derived from a naturally occurring gastric-juice protein, this 15-amino-acid sequence has been studied for its role in wound closure acceleration, angiogenic signaling, and gut mucosal protection — all without systemic growth-hormone activity.

KPV (Lys-Pro-Val) is a naturally derived tripeptide gaining attention for anti-inflammatory and barrier-recovery studies. In macrophage and keratinocyte assays, KPV has demonstrated cytokine modulation and accelerated wound closure, making it a valuable tool for skin and mucosal research models.

GHK-Cu, a copper-chelated tripeptide, is widely used to investigate collagen remodeling, angiogenesis, and hair-follicle activation in cell and tissue models — without systemic hormone effects.

⚖️ Metabolic & Weight Regulation Research

The GLP-1/GIP receptor agonist class has transformed metabolic research in recent years.

Tirzepatide and Semaglutide are among the most studied compounds for appetite regulation, insulin sensitivity, and glucose metabolism. Both are available as lyophilized powder at ≥99% purity, independently third-party tested for consistency across experimental batches.

Retatrutide, a next-generation triple-receptor agonist, has demonstrated unprecedented body mass reduction potential in preclinical models, with additional implications for cardiovascular and metabolic health research.

🧬 Endocrine & Growth Hormone Studies

Tesamorelin, a GHRH analog, enables precise studies of fat metabolism, IGF-1 activation, and endocrine-feedback loops. Its resistance to rapid enzymatic breakdown makes it particularly useful for sustained in vivo protocols.

⚡ Cellular Energy & Longevity Research

NAD⁺ (Nicotinamide Adenine Dinucleotide) is a central coenzyme in cellular energy production, DNA repair, and mitochondrial signaling. Injectable NAD⁺ is commonly used to model rapid replenishment and evaluate downstream effects on ATP activity and oxidative stress markers.

SS-31 (Elamipretide) targets the inner mitochondrial membrane to scavenge reactive oxygen species, supporting studies of mitochondrial bioenergetics and cell survival signaling.
