Hey smallsparrow, are you going to be putting T3 into the equation as well? Even on a bulking cycle useing HGH it will help a lot and actually give you better results from it.
IMO if you're going to spend the kind of $$ you are on 7iu a day for a few months you need to get the best possiable results, slin will help in a very very big way here, but don't get me wrong it's something you need to be very careful with, do as much research as you can and get hold of BigA or BIGKIWI and they'll put you on the right track, KIWI has been on slin for 5 years now and no problems, just need to know what you're doing and be careful.
