Testosterone Propionate

Short-ester testosterone. Faster acting, more frequent injections needed.

Overview

AASTestosterone Ester

Short-ester testosterone. Faster acting, more frequent injections needed.

Effects on Markers

Same effects as other testosterone esters but faster onset and clearance. More stable estradiol levels with EOD injection.

Compound Guide

Ester: Propionate -- 3-carbon chain ester. Rapid release requiring frequent injections. Peak levels within hours, largely cleared within 48h.

Dosage:

  • TRT / Cruise: 25-50 mg EOD (equivalent to ~100-175 mg/week)
  • Enhancement: 100-150 mg EOD (350-525 mg/week) for 8-12 weeks

Injection Protocol:

  • Inject every day (ED) or every other day (EOD) -- mandatory for stable levels
  • IM: 25-29g needle, 0.5-1 inch, delts/VG/quads
  • SubQ: 29-30g insulin needle, abdomen

Key Notes:

  • Best for dialling in E2 -- rapid clearance means quick dose adjustments
  • More injection site irritation (PIP) than longer esters
  • Ideal for short cycles or the last 2-3 weeks of a cycle before PCT
  • PCT can begin 3-4 days after last injection (vs 3 weeks for E/C)
  • Often used in pre-contest protocols to avoid water retention
