I'm actually just about to finish my first and probably last bottles of Valhalla.
I used Test E and Mast E for 4 weeks, 400mg per week. Before starting with Valhalla, I was cruising on TEST 150mg per week. Done my bloods, everything was good. Bought for some crazy price these Valhalla peds, and since started blasting them, haven't really noticed any difference, so I would stay away if you can, theres so many other suppliers, that sell quality stuff. Unfortunately I did not know anything about this forum til after I bought some Valhalla.
