Learn About Peptides
Everything you need to know about research peptides — what they are, how they work, and what to look for when choosing a supplier.
What Are Peptides?
Peptides are short chains of amino acids — typically 2 to 50 — that act as signaling molecules in the body. They play roles in everything from metabolism and immune response to tissue repair and cognitive function. Research peptides are synthesized in laboratories for scientific study.
GLP-1 Receptor Agonists
GLP-1 peptides like Semaglutide, Tirzepatide, and Retatrutide mimic the glucagon-like peptide-1 hormone. They are widely researched for their role in metabolic regulation, appetite signaling, and glucose homeostasis. Tirzepatide is a dual agonist (GLP-1/GIP), while Retatrutide is a triple agonist (GLP-1/GIP/Glucagon).
Recovery & Healing Peptides
BPC-157 (Body Protection Compound) is a gastric pentadecapeptide studied for tissue repair, gut healing, and wound recovery. GHK-Cu is a copper peptide complex researched for collagen synthesis and skin regeneration. KPV is an anti-inflammatory tripeptide derived from alpha-MSH.
Growth Hormone Peptides
HGH 191AA (Somatropin) is recombinant human growth hormone with the full 191 amino acid sequence. CJC-1295 (without DAC) combined with Ipamorelin creates a synergistic growth hormone releasing blend that mimics natural GH pulsatility without desensitization.
Longevity & Mitochondrial Peptides
NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme critical for cellular energy production and DNA repair. SS-31 (Elamipretide) targets the inner mitochondrial membrane to reduce oxidative stress. MOTS-c is a mitochondria-derived peptide that acts as an exercise mimetic.
Nootropic Peptides
Semax is a synthetic peptide derived from ACTH (4-10) that is researched for cognitive enhancement, neuroprotection, and BDNF modulation. Selank is a synthetic analog of tuftsin studied for its anxiolytic and immunomodulatory properties without sedation effects.
How to Read a Lab Report (COA)
A Certificate of Analysis (COA) from an independent lab like Janoshik Analytical shows the HPLC purity percentage, identity confirmation, and actual content weight of a peptide. Look for purity above 98%, matching molecular weight, and a recent test date. All West Coast Peptides products include COAs.
Storage & Handling
Lyophilized (freeze-dried) peptides should be stored at -20°C for long-term storage or 2-8°C (refrigerator) for short-term. Once reconstituted with bacteriostatic water, store at 2-8°C and use within 30 days. Avoid repeated freeze-thaw cycles. Keep away from direct light.
