After 4 weeks it seems the benefits diminish. This is due to receptor saturation. If you have it all planned out for a 5 week run then by all means go for it, but you probably won't see that much from your IGF the last week.

it will largely depend on the dosage that he runs. most run 100 mcg for 4 weeks and oversaturate their receptors. I run my igf for 6 weeks at 50 mcg with no problems.
