Testosterone Enanthate
Long-ester testosterone — the TRT and bulking backbone. Weekly injection, broad clinical history.
- Half-life
- 4.5 d
- Out of system
- ~3 weeks
- Route
- Intramuscular
- Level
- Advanced
Long-acting — weekly dosing keeps levels steady. After the last dose, roughly 97% has cleared in ~3 weeks (five half-lives) — the window that matters for washouts, bloodwork and surgery.
What Testosterone Enanthate is used for
- Restores testosterone to a youthful range — energy, libido, muscle, mood
- The most studied, lowest-cost anabolic with decades of clinical TRT use
- Weekly (or twice-weekly) injection keeps levels stable
How it's typically used
TRT literature: 100–200 mg intramuscular weekly (often split). Higher "enhancement" doses carry proportionally higher risk.
What to watch for
- Suppresses your own production — fertility drops and recovery needs a PCT
- Raises hematocrit, can raise estrogen/BP — bloodwork is non-negotiable
- Controlled substance (US Schedule III); illegal without a prescription in most countries
About Androgens & steroids
- What they are
- Anabolic-androgenic steroids — testosterone and its derivatives. These are drugs, not peptides, and are controlled substances in most countries.
- How they're run
- Injected intramuscularly or subcutaneously on a schedule set by the ester's half-life; a few are oral and hepatotoxic.
- What to watch
- Every one of these shuts down your own testosterone production. Full bloodwork before, during, and after is not optional, and an exit plan — PCT or ongoing replacement — is part of the decision to start, not an afterthought.
