test is AWESOME with gh but i'm thinking he wants to go the ben johnson route and not get too bulked up. although you could work some low levels of test into a cycle.
how much/little weight would you want to add? and what sport do you compete? this will help us point you in the right direction.
HGH will increase your recovery dramatically. If you don't want to gain weight, drop the slin. That shit is dangerous anyway. HGH will make you gain weight to a certain degree though.
