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
