Reported cautions

⚠ Worth knowing. Not a substitute for treatment of a diagnosed anxiety disorder. Western evidence is limited to small studies.

Pharmacokinetics

Published figures give an elimination half-life of ~20 minutes. Similar evidence base/limitations as Semax.

This figure is tagged Limited data in our evidence system. The available data does not support a confident single figure, so this entry is flagged accordingly. Read any curve built from it as illustrative only. You can see the shape this implies between doses in the Half-Life Visualizer, and compare it against every other compound in the Half-Life Data Table. Our sourcing page explains what each tier means.

Remember that an estimated curve is a model built from a population figure, not a measurement of your blood. Individual clearance varies, and for depot injections the figure describes release from the injection site rather than the compound clearing. Half-life explained →

What Peptide Plug does and does not publish

This page carries regulatory status, general context and published pharmacokinetics. It carries no dose, frequency or cycle information — that is a deliberate editorial line, because dosing is a clinical decision rather than reference data. We also do not sell, supply, source or link to vendors for any compound.
