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

The GUIDE Model is described in the Caregiving section and discussed in more detail later in this Workforce section (under Looking to the Future)

They are discussed for overlapping reasons, but they come from different biological concepts, are studied through different mechanisms, and raise different safety and regulatory questions
