T400 is a blend of 3 long acting esters of testosterone. Blends of testosterone are a popular as a way regulate the release rate into the users system. This is a popular blend as it acts as it will allow for a even release of testosterone into your system even when there is a substantial amount of time between shots. it also gives a good bang for the buck so to speak as the total amount of testosterone per shot will be quite high.

As a blend of testosterones it has all the side effect seen with testosterone. It will down regulate by converting to estrogen, and will stop natural test production as well. This will lead to estrogen related side effect as well as a suppression of your hormonal axis which will leave one in a testosterone deficient state once testosterone replacement is discontinued. Estrogen related side effect include bloating, gynecomastia, high blood pressure, etc.


We do not suggest the use of testosterone for women. It is highly androgenic and will easily cause virilization. There are a miriad of altered testoterone derivative that will help with muscular growth that are not as likely to cause the irreversible side effect of virilization; deepening of the voice, body hair growth, clitoral enlargement. Not something most women desire.

Active half-life: 4.5-12 days

Men: 200-1000mg/week

  1. Will

    Decided to change up the cyp which I usually run, for this T400 blend. Injected .75ml twice a week for 16 weeks. Pip wasnt too bad and i got some good gains off it. I will probably run it again on my next cycle.

    worked great for me. but i do need to inject twice a week not once

    got some pip. i injected 1ml twice a week. I got a bit of PIP. product works great, but I would prefer a straight test e t400 rather than a blend t400. no complaints of quality. I just always get PIP when there is Test P in any product. otherwise great experience. Ill just switch to doing test e 250. all the best, Manny

    T400 blend. I didnt know my Alpha north t400 is actually a blend. I like it a lot more than straight test e t400. Alpha north t400 hits me quicker and feels stronger because of the fast acting esters. I inject it 3 times a week vs the 2 times a week i used to with test e t400 I would recommend alpha north to any of my friends. They have realizable and speedy service. Thanks Mike
