i have done aas befor, but never gh, now i got a source for a 5 months supply of jintropin, but i know nothing about it. i would like to know

1. How long do the resluts last?
2. should i stack it with aas, if so which?
3. how long is the cycle, is 5 months too long?
4. Is it good fro my age, or is it just a wast of money?

i am 25, 5'7", 165lb 17% bf, i have been trainning for 6 years, done 3 cycles of AAS, in pretty good shape, but would like to be a be 180 and a bit leaner, hopefully a six pack
