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.
Bro, you may want to dial down the Tren just a touch - you can always adjust up as your body settles into the Tren. This compound can creep up and kick your ass but good and you won't see it coming - if used properly its also the best in my opinion. I started out with 250 mg Tren. Less is more especially if you are implementing Mast which is awesome also. See how it feels first and if you never needed AI before it would be neglectful not to have the compounds on hand that Rusty is recommending. In fact, I suggest you send Rusty a FR request and see if he will walk you through the first four weeks or so of this cycle. On another note, don't take Tren advise from people who have not run the compound. Also, if your diet is not near perfect you will be wasting a great deal of effort (tolorating sides N shit) for nothing. Good luck.
