Trenbolone Enanthate 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. The Trenbolone hormone is the Nandrolone hormone with an added double bond at carbons 9 and 11. This structural change slows its metabolism, greatly increases its binding affinity to the androgen receptor and inhibits it from aromatizing. While this is truly a slight modification, it truly creates a different hormone and one that is far more powerful than Nandrolone.
The average Trenbolone Acetate dose varies based on your cycle and stack. During an off-season bulking cycle, most bodybuilders find that 50mg every other day is comfortable and effective. Some men tolerate up to 100mg every other day with no issues, and they find that this does offers the best results for them. During a cutting cycle, people tend to push the envelope a little more with Tren and utilize doses even higher than 100mg every other day, but not everyone can tolerate these as the risk of side effects increases. No one should ever use more than 200mg every other day, even if they seem to tolerate it well.
