Naps carries one of the best, if not the best GH on the bodybuilding market, Hyge. I would go that route for sure. IGF and GH work very well together. I find that while running GH, I get a greater effect from lower doses of IGF. I would rather use 25mcg post workout for 8 wks, than use 50mcg postworkout for 4 wks. After you have used IGF LR3 for 8 wks, I would take 3 wks off and then repeat. There isn't a bad time of year to use IGF. When bulking up, it helps with adding mass. While cutting, it helps to keep you full on a restricted diet. Using GH and IGF may be a game changer for an advanced athlete that is having a harder time making dramatic gains. If can work your ass off, eat a solid diet and use gh at a decent dose for a year, while cycling IGF, there is a good chance that you see a difference in your physique that you wouldn't have obtained otherwise. Some people respond better than others. For some guys, it helps a little, while for others, it's like a missing puzzle piece that takes them to the next level. 

Best of luck and feel free to come back and talk about your plans as you go
