mast e

So my last cycle I ran Test E and Mast E and I had about half of a vial of Mast E left at the end of my cycle. So I stored it away and the other day I noticed it has changed color to a light pink. What is the reason for this? I'm guessing it's garbage now. Any info would be apreciated...

Hey bros, does anyone know what is the highest concentration of Mast E that will hold? I have only seen it as high as 250 mg/ml, just wondering if there was a reason that you don't see it above that. Thanks in advance.

Well, I figured out what was going on with the low sex drive on Test e, Mast, and EQ......Low E2 was the culprit, I was taking 12.5 mgs per day of Aromasin and that along w/ the mast dropped my e2 down to the bottom, switched back to adex @ .5 eod and within a week, wood is back in full effect...
