Obviously Creatine, Protein and Multi, and a solid Preworkout if thats your thing. Personally, I use LG's EPIC as my staple as some of the new prewrkouts I've used just don't give me the pump that the old stuff used too. I also don't do the whole bulking/cutting thing really anymore. I ran the Trifecta stack a few years back and it jump started me to a new level with bodybuilding. Gained about 8 pounds and lost around an inch in the waist. Check out the Trifecta Andro Kit from LG Sciences. If you however want to look at cutting or bulking, check out the Bulking Andro and Cutting Andro kits respectively. The nice thing about the kits is that it gives you a solid setup to get started with rather than piece together a bunch of different products.
