If you don't want any muscle gains at all compounds like anavar, winnie, Tbol, and primo are your best bet. If you never going to use steroids ever again then just stick to the var alone. Run it at like 60mg a day for like 6 weeks, and do a proper PCT with tamoxifen and depending on your age HCG.
If you plan to do several cycles in your life then you need to understand how these compounds effect you. I would recommend in this instance to rather do some extreme dieting up to new years and drop bf by 5%. It's only 2 months and in that time you can research steroids PCT and all the other things you need to know before starting a cycle. Then for strength increases will little muscle gain you could do a low dose test prop cycle for around 6-8 weeks or a longer ester for 8-12. Both will inrease strength wonderfully and at lower doses gains will be good but not insane. You will in this phase replace the fat you lost with lean muscle gains. Test is also a good drug to gauge the effects of excess androgens in your body. You might run an AI with to prevent excess water retention however there will not be alot if you keep your doses low.
By low doses I am refering to the old doses back when depotrone was king. Something like 200-300mg a week of which ever test ester you choose.
Sorry if I offend you
Its just my point of view
