This is why the protocol for 1 injection every 2-3 weeks of Test Cyp and Enanthate is 8-10 years out dated. Look at the graph.. This is the true biological half-life of T Cyp/Enan as it relates to serum T. Exogenous Test peaks serum T between 24-48 hours and slowly falls back to baseline by day 9. For men on Testosterone only (no clomid or HCG therapy) they are often lower than baseline having levels lower than when they even started due to HPTA suppression. This pretty much equals feeling like crap week 2 and week 3. Men using this protocol experience this rollar-coaster hormone effect as they feel energized and optimal for the first 5 or 6 days then very weak and symptomatic week 2-3.

Whats ideal?-- 1x week injections at the very least IM. My personal favorite-- 1 injection every 3 days SQ. Different protocols are really what's ideal for the patients lifestyle.


Reasons why the 1 injection every 2-3 weeks protocol is still around?
1)quite simply lack of education. The dosing directions that come from most of the commercially avaliable manufacturer of test cyp and E STILL say "Inject 200mg of every 2-3 weeks." WRONG!! Somebody forgot the difference between the physical half-life and the biological half-life.
2) Majority of doctors learn little about injectables because they only learn TRT from their Androgel medical rep. Sad but true.

Men using this protocol statistically have more superphysiologic side effects as well. polycythemia (higher RBC/hematocrit) putting themselves at risks of DVT (blood clot) and PE. (Pulmonary embolism) and higher rate of estrogen aromatase.
