The whole "once you stop taking steroids you lose what you gained" is bullshit. As long as you maintain a caloric surplus diet that is high in protein, you will not lose any muscle you gain on steroids or HGH. As far as losing the anti-aging effects you get from HGH, I have no idea. And I don't know if we are allowed to discuss prices on here, but let me tell you it isn't cheap. The best you could hope for (and it's a long shot) is $20 a day if you're doing 4 IU's.
