A peptide dosage chart, one peptide at a time: its dose range, how often it’s taken, a typical run and the units on your syringe. All 69 peptides in the PepVault library.
A community reference, not medical advice. Each range is what has been studied or is commonly run, never a dose for you.
A peptide analog of CNTF (a nerve growth factor) that promoted neurogenesis and synaptic plasticity in mouse and rat studies from one lab. P21 is more stable than the parent protein and crosses the blood-brain barrier (shown with oral dosing in animals); in those studies it raised BDNF and improved memory. Commonly reported: a subtle improvement in memory, recall and verbal fluency over a few weeks, and for many, little or no effect. No human data.
Used as a nasal spray, so it’s dosed by sprays, not drawn into a syringe.
