Whatever is in the bottle itself should be fine, but the question is.....what's in the bottle?? Serioulsy, I loved the stuff when I took it, but I didn't think I was quite getting 500mg's of test a week from the two injections. And I had the good lot.......after everything I've read in the last 7-8 months since my last cycle, I've been convinced not to touch ara again. 80% of ara bottles out there are PURE bunk, the other 20% ain't dosed right. It's too bad, that's a damn good test mix. Somebody else needs to come out with that mix.
