You're right 40butpumpin, the use of GH and slin should be takin very carfully and do as much research as you can before starting, but the same should be said about anabolics. I've read some posts before saying that they are taking 100mg of anadrol for over 4 weeks or so. This to me is very dangerous and it shows the ignorance of the user. So this goes for everyone taking any type of gear, start off with a low dosage and adjust from there. I'm just telling what worked for me but if 4ui's is what works or you, that's great, you will be saving more $$$.
