Masteron will significantly suppress natural testosterone production making exogenous testosterone therapy important when using this steroid. Failure to include exogenous testosterone will lead most men to a low testosterone condition, which not only comes with numerous possible symptoms but is also extremely unhealthy.
As most will use Masteron in a cutting cycle, it’s very common not to want to use a lot of testosterone due to the high levels of estrogenic activity it can provide. If this is the case, you will find a low dose of 100-200mg per week of testosterone to be enough to combat suppression and give you the needed testosterone.
Once Masteron is discontinued and all exogenous steroidal hormones have cleared your system, natural testosterone production will begin again. Prior levels will not return to normal over night, this will take several months. Due to the slow recovery, Post Cycle Therapy (PCT) plans are often recommended. This will speed up the recovery greatly; however, it won’t bring your levels back to their peak, this will still take time. A PCT plan will ensure you have enough testosterone for proper bodily function while your levels continue to naturally rise and significantly cut down on the total recovery time. This natural recovery does assume no prior low testosterone condition existed. It also assumes no damage was done to the Hypothalamic-Pituitary-Testicular-Axis (HPTA) through improper supplementation practices.
This is the most powerful of cycles designed to harden the physique for a pre-contest or cutting phase while also lending enough anabolic strength to facilitate lean mass addition or even a full-out bulk. All has remained the same as the intermediate Masteron cycle listed above with the exception of the addition of Trenbolone. It has long since been considered that the combination of Testosterone, Trenbolone, and Masteron is a stack that will provide some of the most notable and dramatic physique changes (provided that the user’s nutrition and training is adjusted to favor such outcomes). Trenbolone itself is extremely powerful and cannot convert into Estrogen. In combination with Masteron in such a cycle, and provided nutrition and training are impeccable, the majority of individuals should be able to achieve a competition-worthy physique.
