g4m cant say enough good
got hucog 10000iu pre-mix one or two weeks ago but its so concentrated at 10000iu in 1ml of solution.
great for high doses 500-1000iu or above but hard to gauge lower doses,
so decided to switch back to vitagon for lower more frequent inj,
the hucog is totally pain free very little solution but the vitagon can have a little sting to it sub-c
great stuff.
