Just started my next course of it 2 days ago and am already leaner and more pumped, I sweat all the time when on it though. It happens me during the peak of GH but usually lasts for 15 mins to half an hour with IGF it is most of the day. It works so much better with slin, I put a guy on some who is competing in the European championships tomorrow and he got nothing off it until he started using 4 iu of slin with each shot and then he grew, all this 3 weeks out from a comp during a strict diet. Most people over in this country think GH is the greatest thing ever but it is an overpriced pretender compared to IGF and that is my 100% honest opinion. If IGF didn't leave me so hungry I would use it to cut for my next contest but I know I won't be able to as my hunger sends me proper crazy on it.
