i tried ergo pge-1 at 5mcg, reconstitued and immediately placed in the fridge.... no effects..
i tried mexican pharm caverject and 2mcg gives the desired effects... caverject was even stored in a heated garage, reconstitued, over the course of the summer, and still worked each and every time.
i tried another internet source pge-1 and the same non-effect.. so not sure the difference between caverject and these internet sources..
