I've actually been studying endocrinology and hormones for the best part of the last 10 years, as well as trying them on myself.You can do a simple PCT with Clomid or Enclomiphene Citrate. I think everyone knows that :). And no one can be sure about the results, you actually just try it out and see if it works. I guess you are new into this xD it gets normal after a while...
For one, both anecdotal evidence and studies show that PCT ancilliaries have little to no benefit over "just waiting it out" as far as hpta and testicular function recoveries are concerned secondary to AAS use.
Secondly, you can try all the PCT you want after a few doses of Tren or Trest, you most likely will need around 9 months to recover, and no amount of HCG, clomiphene or enclomiphene will speed up the process.
Lots of bodybuilders have burnt their testicules trying those drugs, hence the more and more popular blast&cruise strategy.
