Testomastren 400 - ISIS Pharma


Testosterone 400 is one of the strongest blends of 3 long acting/long chain ester Tests. It contains 400mg per ml of various Esters which are:

  • Test Enan 200mg
  • Tren Enan 100 mg
  • Masteron Enan 100mg

It will increase nitrogen retention in the muscle with reports of increasing IGF-1 in the muscle tissue and liver. It also has an active role in repairing exercised damaged muscle tissue through satellite cell activity.

It most closely resembles the design of Testoviron, containing a mix of rapid and medium/slow acting esters. The only difference between the enanthate/propionate blend of Testoviron and Testomastren 400 are the dosages of the esters, and the addition of Testosterone Cypionate.

With no visible distinction, Testosterone levels peak and drop in parallel with these two agents, Testosterone Cypionate with Enanthate.

It has the ability to increase muscle mass and strength while cutting fat. However you will get a bit of water retention from this blend but you'll also be making quality gains while you're on it so the results will last.
