i am going to start igf-1 LR3 during the last 2 weeks of my test p tren a cycle. dave calls for only 10mcg post workout for a cycle of 4 weeks on 2 weeks off, repeat. the main purpose of taking the igf is to keep my gains from my cylce(growing some more would be nice too). my question is who has tried this and what were their results? i have heard of some taking as much as 100mcg pw, but i heard the more you take the quicker your receptors shut down..... just looking for any advice, thanks
