When used as an ancillary, it can be taken by male athletes and bodybuilders all throughout their cycle length at 50 – 100mg per day, as there is no limit to how long it can be utilized for. Some individuals prefer to also run Proviron as a PCT (Post Cycle Therapy) drug in order to reduce Estrogen levels and boost fertility. Although this can be done, there are much better compounds with similar (and stronger) effects for PCT. When the risk of even weak endogenous Testosterone suppression is thrown into the mix with Proviron, it is advised to avoid the use of Proviron for PCT purposes unless there are no other options available. During a period in which individuals are attempting to recover their natural endogenous Testosterone levels, any threat no matter how minimal to endogenous Testosterone production should be unwelcome and avoided at all costs.
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
