Testosterone Enanthate
Long-ester testosterone. Most common injectable AAS. Used for TRT and cycles.
Overview
Long-ester testosterone. Most common injectable AAS. Used for TRT and cycles.
Elevates testosterone, estradiol (via aromatization), suppresses LH/FSH, increases haemoglobin/haematocrit, worsens lipids (moderate), can elevate liver enzymes slightly
Compound Guide
Ester: Enanthate -- 7-carbon chain ester. Provides a slow, steady release of testosterone over several days, peaking ~24-48h post-injection and tapering over 4-5 days.
Dosage:
- TRT / Cruise: 100-200 mg/week (target trough 20-30 nmol/L)
- Enhancement: 300-600 mg/week for 12-20 weeks
Injection Protocol:
- Inject 2x/week (e.g. Monday/Thursday) for stable blood levels
- IM: 25-27g needle, 1-1.5 inch, glutes/delts/VG
- SubQ: 27-30g insulin needle, 0.5 inch, abdomen/love handles (viable for TRT doses)
Key Notes:
- Gold standard for TRT and first cycles
- Aromatises dose-dependently -- monitor E2 if symptoms arise
- Allow 4-5 half-lives (~3 weeks) to clear before starting PCT
- Interchangeable with Cypionate at the same mg dose
