Tri-Ester Test 400

It is an oil-based injectable testosterone blend combining three long esters, enanthate, cypionate and decanoate, at a total concentration of 400mg per millilitre. All three esters release testosterone slowly over one to two weeks, which builds up steady blood levels rather than a quick spike. It is used as a base compound for bulking, driving strength, size and recovery.

A common beginner approach is 200mg per week split into two injections, for example 100mg on Monday and Thursday, rising to 300mg per week after four weeks if bloodwork and tolerance allow. Most male users stay in the 400 to 800mg per week range over a cycle of 8 to 12 weeks. Because all three esters are long-acting, twice-weekly injections are enough to keep levels stable, there is no need to inject daily.

Testosterone aromatises to oestrogen, so water retention, gynaecomastia, acne and oily skin are possible, alongside raised blood pressure and hair loss in those genetically predisposed. An aromatase inhibitor such as anastrozole is commonly used to control oestrogen, and hCG is often run during the cycle to support testicular function. A full course of Post Cycle Therapy is required afterwards, and because the decanoate ester clears slowly, PCT is usually started two to three weeks after the last injection rather than immediately.

A single-ester product such as testosterone enanthate has one release curve, so it is simple to plan around with a predictable half-life. Tri-Ester Test 400 layers three esters of different lengths to smooth out the release further and extend detectability after the cycle ends. In practice both are dosed and injected in a similar twice-weekly pattern and produce comparable results for bulking, the main difference is the longer wash-out time after stopping the tri-ester blend.

Yes. Testosterone suppresses your own natural production, so PCT is required once the cycle ends. A typical protocol is nolvadex 40mg daily for two weeks then 20mg daily for two more weeks, or clomid 50mg daily for four weeks, started two to three weeks after the final injection to allow the longer esters to clear first. hCG through the cycle can help maintain testicular function ahead of PCT.
