Test E (Testosterone enanthate) plotter

The default long-ester comparison. About 72% parent hormone. Twice-weekly dosing is a common way to flatten peaks and troughs versus a single weekly pin.

Also called Testosterone enanthate, Test Enanthate, Enanthate, Test E 250.

Compare with Test C, Test P, Test U.

Ester fraction ~0.72 from testosterone ester tables; half-life ~4.5 d from the steroidplot/Behre-era community PK set.
