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.
For decades many athletes who use anabolic steroids have supplemented with the SERM Tamoxifen ( Nolvadex ) to combat such issues. Nolva, as it is commonly known acts to block the estrogen from binding to the receptors; it does not reduce estrogen as is commonly thought by many who take it. However, while this is a solid prevention measure, for many it is not enough and only an aromatase inhibitor will do. An aromatase inhibitor will actually reduce the amount of estrogen in the body and bind it what’s left. While perhaps not completely accurate but to give you an idea, for the prevention of Gynecomastia when steroids are present look at Nolva like Aspirin and aromatase inhibitors like morphine; far stronger. The two most common aromatase inhibitors that will in most cases get the job done include Anastrozole ( Arimidex ) and Femara ( Letrozole .)
It is important to start a PCT once you finished a steroid cycle to avoid a dramatic loss of the mass gained. The question on how soon to initiate a PCT depends on the kind of steroids you used. If your cycle is comprised of orals, which have relatively the shortest effect on the body, it is advised to start immediately. Some say PCT can begin as early as the last day of the steroid cycle. If short-acting esters or water-based injectables, PCT is recommended 4-7 days after the last injection. In the case of long-acting esters, it should be around 10-14 days after the last injection.
