Test base can mean only one thing, TESTOSTERONE. Nothing else would suffice.
I am always interested in seeing people who run orals only cycle. I did that before and the results always sucked for me. Things like Phytoserms and HCGenerate are great for PCT but they are no substitute for Testosterone. These OTC products will never give you a supra-physiological level of Test. It is simply not possible.
If you don't have the balls to pin, you have no business doing steroids. PERIOD.
