I made a blend of some of my homebrews. I put 1.5ml of mast e @ 400mg per ml, 1.5ml of tren a @ 150mg per ml, .6ml of test 400, and .9ml of tren e @250mg per ml. I want to use this in a slin pin 3 days a week. It looked normal and swirly at first. Came back in 2-3 hours and it was really dark. The mast is pretty dark at that concentration.
