Again, it begs the question, why supplement with Trenbolone-Enanthate over other Tren forms? The only reason one would choose the Enanthate version over any other Tren form is based on injection frequency. If you supplement with Trenbolone-Acetate, you're going to have to inject on an every other day basis. Some will even inject on a daily basis due to the short half-life, but every other day is more than sufficient. If you supplement with Parabolan, you're going to find a 2-3 times per week schedule to be warranted, with 3 times per week being optimal. However, Parabolan is extremely expensive, the original is no longer made, and this form is commonly counterfeited and simply not as available as the Acetate version. At any rate, if you choose Trenbolone-Enanthate you'll be able to limit yourself to two injections per week. In truth, you might be able to get by with one injection every five days, but two times per week will be optimal. In any case, there is truly no true advantage over this version of Tren in-terms of direct performance, and anyone who claims there is has suffered from some placebo type effect, or simply doesn't know what they're talking about.
