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.
Dave, let me clear the air here on some of the confusion… I recommend the 1 vial cycle for someone who is either A. younger or either B. already has high levels of natural testosterone. Now, the typical middle aged male who already had declining levels of natural testosterone COULD go with 500 mg/wk for 10 wks. Recovery is recovery at that point and if you’re going to do it then I see nothing wrong with getting the most out of that first cycle. But what you have to realize is a male with a starting level of high average test levels can still yield the same benefits of someone who is middle range-low end of normal and uses 500mg/wk of test. In either case the person can still gain a solid 20 lbs of muscle from either 1 or 2 vials, the determining factor on this is what they were at to begin with
