Personally, if you're not going to run a SERM (which you should at least have on hand) in your PCT, then all four of those OTC supps would be good; they all do different things.
The PCS has reseratrol in it which acts as a natural SERM. It also has Icariin which will help boost testosterone and increase libido.
Hyperdrol X2 contains 6-bromo which is an effective aromatase inhibitor.
The Mass FX will suppress SHBG increasing free test and the Retain 2 is an anti-cortisol that will help you lean out.
Other than a SERM, the above pretty much has you covered. The only thing I might add is some creatine.
Dose the PCS at 4 caps/day, the Hyperdrol at 2 - 3 caps per day, the Mass FX at 4 caps/day and the Retain at 3 caps per day. Make sure to taper the Hyperdrol at the end of PCT to avoid estrogen rebound. The Retain can also be tapered if you like.
Best of luck!
