Got some supertest 450 and also had to try some Balkan sustanon after hearing so many good things about it. Both are fantastic and as you can see in the picture, I had no patience to take pictures before starting them. Balkan is nice and smooth and is some excellent test. I've been running sp labs supertest for a while now and it is definitely some strong stuff. It will give u a nice knot though unless u mix it, but I've gotten used to it. So far everything I have tried from ashop has been outstanding quality. Hats off to you!!! Thanks again.
