Testosterone enanthate 250mg is used in bodybuilding as a long‑ester “base” androgen to promote muscle hypertrophy, strength, nitrogen retention, and training recovery, often in bulking or recomposition phases. Its intramuscular depot provides a multi‑day release; reported elimination half‑life is about 4.5–9 days, leading users to dose weekly or split weekly to moderate peaks and troughs.
