For someone with neuropathy affecting nerves in the feet, where the nerve distance from the spinal cord can be over a meter, even dramatically accelerated regeneration takes months to produce measurable clinical improvement

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

However, systematic reviews and randomised controlled trials supporting these claims are notably absent from peer-reviewed literature
Neurodegenerative conditions like dementia use lower doses
The treatment can take effect as soon as 3 to 5 days after the treatment, with the final results becoming visible after about 2 weeks
For health professionals working with clients interested in peptide research, understanding proper dosing protocols is essential
