I am on a treatment Rx of 1Ml/week and have been getting testosterone cypionate from the pharmacist. Unbeknownst to me, I was getting a generic brand. Today I was advised that the pharmacy was out of the generic and I was provided with a more expensive "brand name" of Depo-testosterone cypionate. It is the same dosage and strength. My question is, what's the difference (if any) between a bottle of "testosterone" and "Depot-testosterone"?
