You can buy sharps also, but if you want a better container that you probably already have use either a liquid laundry detergent bottle (best) or a Protein jar. I am really anal and after filling I take spray in wall insulation and spray that into the container then put the lid on real quick and tape it that way it forms a solid block. By the way if you google it you can get the state by state procedures where I live a bleach bottle in the trash (not recycled) is the prescribed method.

As far as stuff other than cyp for TRT a lot depends on the patient and the amount of cyp used. Many will need a small dose of an AI to keep estro in check and many will have to donate blood to get rid of extra red cells generated.
