Regardless of purpose, be it bulking or cutting most will find Trenbolone-Enanthate to be very effective in the 300mg-500mg per week range with 400mg per week generally being a very solid dose. Yes, you can use more but most will find doses that get much past 500mg per week to be a little less side-effect friendly, especially if they enter the 600mg per week range and almost assuredly if they surpass 700mg per week. Regardless of dosing most will find 8 weeks to be decently effective with 12 weeks of use generally being as far as you want to go. If your cycle is extended past 12 weeks it’s normally best to substitute another anabolic hormone in Tren’s place in-order to keep progress alive; yes, our body will adapt.
As for what you should stack Trenbolone-Enanthate with, simply pick whatever you want as this hormone stacks well with all anabolic steroids. However, it is highly recommended that testosterone be part of your stack as Trenbolone in any form will greatly suppress natural testosterone production. Many individuals also find supplementing with the T-3 hormone to be very useful as levels generally fall when Tren is present. Further, as responsible use is important a good Post Cycle Therapy (PCT) plan should occur after the cycle’s completion. In the case of Trenbolone-Enanthate, if your cycle ends with this steroid in play your PCT will not want to begin until at least 2 weeks have passed since your last injection.
Other significant adverse effects of testosterone supplementation include acceleration of pre-existing prostate cancer growth in individuals who have undergone androgen deprivation; increased hematocrit , which can require venipuncture in order to treat; and, exacerbation of sleep apnea .  Adverse effects may also include minor side-effects such as acne and oily skin, as well as, significant hair loss and/or thinning of the hair, which may be prevented with 5-alpha reductase inhibitors ordinarily used for the treatment of benign prostatic hyperplasia , such as finasteride .  Exogenous testosterone may also cause suppression of spermatogenesis , leading to, in some cases, infertility.  It is recommended that physicians screen for prostate cancer with a digital rectal exam and prostate-specific antigen (PSA) level before starting therapy, and monitor PSA and hematocrit levels closely during therapy.
