it depends on what cjc 1295 u want to take, there's with Dac which gives it a half life of 8-10 days, or there's cjc 1295 mod grf 129 aka no dac. This has a half live of about 21-30 minutes. I've read that the dac version causes GH bleeding (2011). The 129 version simulates a natural action of the gh being released. usually 3 times a day. once in the am, post work out, before bed. This should be stacked with Ghrp2, ghrp6, or ipam. depending on what ur looking for and your vulenrability to your body... Ipam is supposdely the safest because it doesnt' increase cortisol levels. Ghrp2, has actually been government tested with the mod 129.. Yeilding the best results, the ghrp6 or hex works as well but can't really remember more at this moment in time. I know it causes vast hunger issues... Also you should know about how to fast the carbs with this..
