I dont have testicals lost em to cancer is there any kind of risks for gear use?

Hey yall about 2 years i lost my testicals due to cancer made a post about it then about TRT help. Got that all under control now my question is if I got onto any kind of Gear or peptides do I have any kind of hormonal risks? Im not sure how to really ask this question im ignorant to most of this so any insight would be appreciated. Where i get my TRT i would also be able to get deca and some peptides but im not sure if I should or want to start any of that.
