You certainly don't need to carb cycle. AFAIK most professional BBers just do staright macros with a refeed every once in a while. I just do it for the satisfaction aspect of having huge carb meals PWO.
Yup, hormones might take a hit with long periods of very low fat, but how sensitive you are for that is also individual. By doing more carbs, you possilby get more energy for your workouts but trade it for less libido and other issues related to hormones. The reasoning is that if it's a relatively short cut you're not gonna screw your hormones over and being "less manly" for a while is ok if you get better performance.
I don't take that many supps atm.
3g fish oil
3000 ui vitamin d
1 or 2 capsules ZMA
45g Intraworkout carbs (dextrose). I lift with zero carbs pre workout and it takes me 1.5-2 hours to get through the whole session so these provide some energy and help recovery a bit. Just started with it and gonna assess it after some weeks. Might shift these to the post workout shake instead.
When I'm back home, I'm gonna buy vitamin C and add Leucine to intra- or postworkout shake.
