Medical history provides context
Nandrolone formulations have been used or studied medically in defined populations. That history helps describe the molecule but does not turn community use into the same clinical setting.
Formulation names matter
Nandrolone decanoate and nandrolone phenylpropionate are related esterified formulations with different release characteristics. A source or lab record should preserve the exact claimed form.
Match claims to evidence
When a claim comes from a study, record the formulation, population, comparator and outcome. When it comes from a member report, label it as an observation and keep product identity and co-use in view.
