Trenbolone enanthate is one of the strongest steroids available today. It is roughly three times more anabolic than testosterone and a very potent androgen as well. Use of Trenbolone often leads to incredible gains in strength and solid muscle mass. Trenbolone doesn't convert to estrogen, therefore the gains seen off of this steroid are lean, quality muscle mass. Trenbolone enanthate acts on progesterone receptors and can cause related side effects. Progesterone side effects are similar to those of estrogenic side effects and can include things such as bloat and gyncomestia.
