I would hold off on the clen. I started my IGF 1 week before PCT. Haven't noticed any big difference. I have leaned up a little, but I am still waiting on that three dimensional look every one else is seeing. I think alot may be that I'm feeling the side effects from the clomid thats making me not want to work out very hard, but I keep pushing. I've been on for 15days now at 40mcgs. Protien intake is high and carbs low. We'll see how everything turns out.
