Anti-aging and longevity peptides Epithalon: Standard shelf life: 28-30 days refrigerated Maximum: 30-35 days Short peptide sequence, stable Thymosin Alpha-1: Standard shelf life: 28-30 days refrigerated Maximum: 45 days (pharmaceutical grade) Relatively stable peptide Semax and Selank: Standard shelf life: 28-30 days refrigerated Maximum: 30-35 days Short peptides, stable Sexual health peptides PT-141 (Bremelanotide): Standard shelf life: 28-30 days refrigerated Maximum: 45 days (pharmaceutical Vyleesi) Stable peptide Melanotan II: Standard shelf life: 28-30 days refrigerated Maximum: 35-40 days Relatively stable Copper peptides (GHK-Cu) GHK-Cu injectable: Standard shelf life: 28-30 days refrigerated Maximum: 30 days (copper can catalyze oxidation) More sensitive than other peptides due to copper ion Special note: Copper peptides may show visible degradation (color change to greenish/blue) if stored too long
For example, peptides like MK-677 Ibutamoren stimulate growth hormone secretion, which supports muscle growth, enhances fat breakdown, and improves overall metabolic function
More severe reactions involving widespread hives, swelling, difficulty breathing, or dizziness require emergency medical care
