Is there any difference between big name depo test and generic? I purchased my last 2 10ml bottles of Pfizer Depo Testosterone from Costco for around $58. Now they stock generic brand West Ward. I called several local pharmacies and most all have this brand. They can order the Pfizer but the cheapest I have found is $147, where the West Ward is around $55. Have any that have changed brands noticed a difference?
