All anabolic/androgenic steroids when taken in doses sufficient to promote muscle gain are expected to suppress endogenous testosterone production. Without the intervention of testosterone-stimulating substances, testosterone levels should return to normal within 1-4 months of drug secession. Note that prolonged hypogonadotrophic hypogonadism can develop secondary to steroid abuse, necessitating medical intervention. Primobolan® is generally described as having a low impact on endogenous testosterone production. While this may be true in small clinical doses (20-25 mg daily), this may not be a major distinction when used for physique- or performance-enhancing purposes. In one study, more than half of the patients receiving only 30-45 mg per day noticed a 15-65% suppression of gonadotropin levels. 585 While this is far from having no hormonal impact, the suppression caused by methenolone acetate may still be less pronounced than with many other agents. If Primobolan® is used at moderate doses for less than 8 weeks, hormonal recovery should not be a protracted experience.
For example, anabolic steroids such as Testosterone have a tendency to promote water retention through their ability to be aromatized into Estrogen via the aromatase enzyme. While such an effect might not be a concern for a strength athlete or a powerlifter (such an effect might even be beneficial or desired in such sports), this is not a desired effect for athletes involved in sports that involve speed and swiftness, such as sprinting. Instead, a sprinter, for example, would more likely opt for an anabolic steroid such as Stanozolol ( Winstrol ) or Oxandrolone ( Anavar ), which are two anabolic steroids unable to convert into Estrogen and therefore the issue of water retention, and therefore the issue of added weight that would slow the athlete down is avoided. Many athletes may also elect to ‘stack’ anabolic steroids in a given cycle (stacking refers to the practice of combining more than one anabolic steroid in a cycle). In the case of cycle stacks, an individual might be able to increase the synergy and synergistic effects between the anabolic steroids to create a highly anabolic environment or to create a stack that might assist the user in favoring certain particular athletic or physique goals. These are some of the major reasons as to why the development of different types of steroids has been done.
With category 2 Trenbolone side effects in mind this is the reason it is always best to stick with short or small ester based Tren such as Trenbolone-Acetate. If the negative reactions become too strong if you are using a small ester Tren form you can simply discontinue use and your system will be clear of the hormone in a matter of a 2 maybe 3 days. However, if you're supplementing with large ester forms such as Trenbolone- Enanthate and problems arise you can still discontinue use but you're going to be dealing with the problems for as long as 2-3 weeks as it will take this much time for the steroid to begin to clear.
