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.
While 8 weeks will be our minimal time frame, 12 weeks is far more efficient, with 16 weeks being the gold standard. Absolutely, you can run cycles that extend past the 16 week mark, but the only ones who will typically have a need for this will be advanced competitive bodybuilders . In any case, for the sake of your health you will need to plan off-cycle periods. You need to allow time periods where there is not a high influx of hormones so as to allow your body to normalize and relieve it from stress. Failure to do this can really mess with your natural hormone production, and in many cases lead to you lifelong hormone therapy needs.
In either case, both men and women, Anavar can be used for far longer than most oral anabolic steroids due to its low liver toxicity rating and further as it does not appear to taper off in benefit as fast as many other oral anabolic steroids. The majority of Anavar users will supplement for 6-8 weeks but longer durations of 12 weeks are not uncommon, especially during female contest preparation time. Keep in mind, the leaner you are the greater the results will be, meaning, they will be far more pronounced; for this reason most women will choose Anavar during the latter half of their diet to reap the greatest reward.
