- Growth Hormone Secretagogues
- Ipamorelin, CJC-1295, MK-677
- 200–500 mcg per administration
- 28 days refrigerated in bacteriostatic water
- GH axis modulation, anabolic pathway studies
- Best for facilities with consistent refrigeration—compounds are stable and forgiving during reconstitution
- Tissue Repair Peptides
- BPC-157, TB-500
- 250–1,000 mcg per administration
- 28 days refrigerated; BPC-157 is light-sensitive
- Wound healing models, tendon repair research, gastric protection studies
- Requires strict light protection post-reconstitution—wrap vials in foil or use amber glass
- Metabolic Modulators
- AOD-9604, 5-Amino-1MQ, MOTS-C
- 100–500 mcg per administration
- 28 days refrigerated; MOTS-C degrades faster in solution
- Mitochondrial function research, lipolysis pathway studies
- Best for short-term protocols—these compounds lose potency faster than GH secretagogues after reconstitution
- Nootropic Peptides
- Semax, Selank, Dihexa
- 21 days refrigerated (shorter stability window)
- Cognitive function models, neuroplasticity research, BDNF modulation
- Reconstitute in smaller volumes (1–2mL) to reduce waste—shorter shelf life demands precise protocol planning
- Immune Modulators
- Thymosin Alpha-1, Thymalin, LL-37
- 500–2,000 mcg per administration
- 28 days refrigerated; LL-37 requires pH-neutral reconstitution
- T-cell function research, antimicrobial peptide studies, immune senescence models
- Higher dose requirements mean larger injection volumes—verify syringe capacity before ordering
- This comparison table covers the five most common peptide categories ordered by research facilities placing their first peptide order. Choose peptides based on your protocol's endpoint requirements and your facility's cold chain infrastructure. Facilities without pharmaceutical-grade refrigeration should avoid peptides with shorter reconstitution stability windows like nootropic peptides, which degrade 30% faster in standard refrigerators.
