Tren E 200 injection is a 19-nortestosterone (19-nor) anabolic androgenic steroid. The 19-nor label refers to a structural change of the testosterone hormone in that it lacks a carbon atom at the 19th position.
Tren E (Trenbolone Enanthate) is used among experienced users rather than bare beginners to Trenbolone, who will most often elect to use Trenbolone Acetate due to the short half-life and therefore relatively quick clearance from the body.
Tren Enanthate 200mg is simply a modified form of Nandrolone, which itself is simply a structurally altered form of testosterone. The structural change slows its metabolism, greatly increases its binding affinity to the androgen receptor and inhibits it from aromatizing. It has anabolic rating of 500 and an androgenic rating of 500.
Tren E (Tren Enanthate) is a long ester variant of the hormone Trenbolone. It is increasing the amount of nitrogen that can be taken up by muscles.
