Overall, enanthate is an excellent bulking drugs and should form the foundation of any juicer's mass aresenal. Testosterone is also very friendly on the liver and kidneys and has very low toxicity. Just keep in mind that enanthate, and any testosterone, will greatly and rapidly shut off your natural production. This will usually occur inside of two weeks. You will notice the 'boys' shrinking within this time. This is also dose dependent, but even a low 200mg dose of enanthate will shut off your natural testosterone within four to five weeks. Enanthate is a popular birth control agent given to many males all over the world, just not in the US.
It was once commonly used during PCT in the belief it will aid testosterone restoration, however this is flawed due to its mechanism of action. The drug mimics the effects of LH in the body, stimulating the Leydig cells to produce testosterone in the testes . This can be fruitful in rectify existing, or avoiding testicular atrophy on cycle. It will not aid the process of recovery in the post cycle phase however, as the drug will bring about heightened oestrogen levels due to the greater aromatising of the testosterone being produced in the testes , thus bringing about greater inhibition of the HPTA .
Trenbolone is also much more potent than testosterone at suppressing endogenous androgen production. This makes clear the fact that estrogen is not the only culprit with negative feedback inhibition, as here there is no buildup of this hormone to report here. There is however some activity as a progestin inherent in this compound, as trenbolone is a 19-nortestosterone (nandrolone) derivative (a trait characteristic of these compounds). However it seems likely that much of its suppressive nature still stems from its powerful androgen action. With the strong impact trenbolone has on endogenous testosterone, of course the use of a stimulating drug such as HCG and/or Clomid/Nolvadex is recommended when concluding steroid therapy (a combination is preferred). Without their use it may take a prolonged period of time for the hormonal balance to resume, as the testes may at first not be able to normally respond to the resumed output of endogenous gonadotropins due to an atrophied state. Those who have used Trenbolone regularly would often claim it to be indispensable. A daily dosage of -75 mg is the most popular range when running a cycle. While Trenbolone is quite potent when used alone, it was generally combined with other steroids for an even greater effect. During a cutting phase one could add a non-aromatizing anabolic such as Winstrol or Primobolan. Such combinations will elicit a greater level density and hardness to the muscle. One could also bulk with this drug, with the addition of stronger compounds like Dianabol or Testosterone. While the mass gain would be quite formidable with such a stack, some level of water retention would probably also accompany it. Moderately effective anabolics such Deca-Durabolin or Equipoise would be somewhat of a halfway point, providing extra strength and mass but without the same level of water bloat we see with more readily aromatized steroids.
