Starting my first cycle

Hi I’m 21m 6,4 87 kg and I’m been using peptides to look better KPV and copper pep and also glutathione for skin CJCIPA for putting weight on. But I’m also looking into doing test I’ve been seeing lots of options on what to take but don’t know and I also wanna keep my balls I also heard there’s something you can take while on cycle, there’s a lot to choose from test anavar I obviously don’t wanna do trenblone but something that will give me a good kick start maybe mk677 to just eat more but idk I wanna do a cycle the most healthy way possible I’m obviously gonna get my bloods done and there’s multivitamins you can take that are for cycle support. Im obviously eating right now processed carbs with cjcipa and my roommate is a PT so I can get him to right me up a plan. But what I’m really asking for is what is the best cycle stack to start off with and dosages?
