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.
While ordinarily there is no particular point in using more than one Class I steroid in a stack, as none of them do a job at building muscle that the others do not, where one is concerned about side effects that are particular to another Class I steroid being used, it can make sense to use a more moderate dose of that steroid and to employ Masteron for the remainder of the desired Class I activity. In this case, as the other such compound will also be contributing substantially to providing this activity, a moderate Masteron dose such as 100 mg every other day can yield sufficient total such effect.
