I've been using 4iu of hgh daily and 2x200mg of test each week. I have a couple of vials of Sermorelin GHRP-2 GHRP-6 (6mg each) and was wondering if I can stack it with the hgh and if so, when I should take it. I usually take my hgh 2iu when waking up and another 2iu in the afternoon. Any thoughts?
