Educational research, not medical advice.

Half-Life Optimization provides educational information about scientific research. Content is not medical advice and should not be used as a substitute for care from a qualified healthcare professional.

We do not sell peptides, publish product purchasing buttons, provide dosing protocols, or encourage readers to take experimental compounds. We do not present cell or animal research as established human outcomes.

Evidence standard

We distinguish mechanistic evidence, animal evidence, human evidence, and unknowns. When reliable source information is unavailable, we prefer leaving a topic for future review over inventing citations.
