I'm using it right now. Second time.
Half life 4-4.5 days, so you can inject twice a week. But, it's only 100mg/ml, so you will have to inject more often, probably(don't know what your weekly dosage is)
It leaves sore site in my quads, and very sore site and bruise in glutes. I wouldn't advice to inject more then 2cc of it at once. Better, if you mix it with some other steroid, in the same syringe. I mix it with T200, it helps to lessen the soreness.
It's good quality and I like the gains from it, a lot.
