I had received these awhile back and have so far gone through the GHRP-2 and the MOD GRF 1-29 (CJC-1295 W/O DAC). These were tested while the test subject was also using anabolics so probably not the best conditions to gauge the effects of each product. I can say without doubt that the test subject experienced joint pain relief from the GHRP-2 by setting up several different tests, basically the joint pain came back if the GHRP-2 was not administered. The GnRH (Triptorelin) has peaked my interest from reading how it positively effects LH and FSH release though I'm being extremely cautious as it appears that at high doses it may have irreversible effects. I had initially tested this, (100mcg shot) while the test subject was also using anabolics to see if it acts similar to HCG, where no effects were observed which leads me to believe this should be tested while anabolics have been stopped for a good amount of time. I have 1 more bottle of this that's been stored in the freezer though I will probably end up getting more so it's fresher come time when the test subject is off all other meds and ready for PCT.
