I've read numerous sources discussing the IGF-1 reduction by taking caber. In the past on tren cycles I've used prami, and it's worked decent for preventing negative sexual sides. On the other hand at the dose I need to maintain libido (~1mg) it turns me into a zombie! This has always had me interested in trying caber, but the reduction in IGF-1 is not a good thing afaik. I'm also on HGH or IGF-1 LR3 most of the year...
