Gains wise with a great diet and a PCT will be about 15 pounds bulk.
Of that 15 like 3-5 or so will likely be fat/water, so you will lose a few pounds or so after you stop taking the gear, simply due to losing water from the muscle.
And depending on your diet and training you will get a pound or 2 of fat.
I would say mabey 7-10 pounds lean if you do it perfectly, and its your first cycle ever.
Dont get me wrong 10 pounds in 6 weeks is freaking awesome, but if you were to take that money, buy some dbol, a bottle of test, and an SERM for PCT youd see more like 25 pounds on your first cycle.
Injecting is a bitch when you first start out, do you know anyone personally who uses that would be willing to "hold your hand" for the first couple injects ?
Check your syringe and shit, and answer questions if you get a splutter or hit a nerve.
