my buddy had to get rid of his stuff. so he gave me like 8 vials of Depo-Testosterone Cyponate 100mg. and like 30 vials of 1mg vitiman b12...just curious on the depo brand...had great results from the QV cyponate. hows the Depo...and doctors, and even roid vets say inject 1cc of B12 with any hormone...whats the B12 for? never got too cleared up on it.
