modafinil is a prescription stimulant drug, like most add stimulants it can make you anorexic and in the zone, as a day in day out thing it is a no go IMO for a few reasons mainly anorexia, some dr's say it increases heart rate and some say no and possible cardio hit, it might help you get some homework done or study some bjj tapes but making you a better mma or bjj athlete I don't see it. I have taken all the main stimulants out there for a test drive as well as nootropics.
CILTeP is regarded by biochem experts I trust as horseshit, its a stack designed by a dude from longecity where people post of profound experiences with fish oil, lots of wack jobs. I am quite certain anyone claiming anything big from a ciltep stack is either a bullshit artist or a nice guy exhibiting a placebo effect, either way its a waste of time.
Rhodiola rosea is a high quality adaptogen herb, it boosts dopamine, is good for aiding stress and depression and just good to dose a few times a month during the day when stressed. One of the few supplements out there that actually does something.
Ashwagandha is another high quality adoptogen. Felt calm and focused with it but I also take it in combo with other things like b12.
Adaptogenic herbs, multis, b vitamins, creatine, protein, fish oil, magnesium, vit d, melatonin, probiotics are all good for physical & mental health and sure could possibly aid bjj.
