when i was about 19 or so and 6 oxo first hit the market i did the same thing. i took about three cycles of it or so, but with not for a post cycle to a ph, just to get some natural test boost. i did feel it gave me more energy and helped me synthesize protien a little better, but in the end its still a synthetic answer to regulating your hormones which when your body is still naturally growing and producing your hormones in large amounts, theres no need to be playing god with your test yet. pound the creatine and the protein, and work on natural test raising. lift heavy sets with a workout built around compound lifts (deadlift, squats, bench press, bb rows) , get lots of natural good fats from peanuts almonds and fish oils. dosing glutamine in extremely small amounts throughout the day also has been proven to raise test (like 2-3mg, glutamine can cause depression in large amounts so dont supersaturate), and maybe if you really feel you need it, tribulus for an herbal answer to the oxo. eat like a fiend multiple times after you work out but all lean proteins and carbs. soon after i was done fooling around with oxo, i took the same approach listed and put on more lean mass then i ever had in my life.
