Thanks! Is there a big risk of heart damage with 5-htp? I was taking melatonin for 6 months instead of 5-htp, should I return to that?
By basic stack I guess I mean one that I could take most days without much changing. I've read some crazy experiments and stacks in here and I like the idea of just taking 4 or 5 nootropics and leaving it at that. I'm looking for the ones with the most bang for their buck, in a pareto principle kind of way.
You should replace 5-htp with L-tryptophan, its one step before it in the Serotonin-Melatonin Synthesis ladder and is much safer for the heart. For reference, this is the serotonin-melatonin synthesis ladder:
L-tryptophan-->5-htp-->Serotonin-->Melatonin
L-tryptophan is transported to the brain, once inside the brain it is converted to 5-htp, which is then converted to Serotonin. At nighttime Serotonin is broken down into Melatonin.
So L-tryptophan gives you 5-htp, Serotonin and Melatonin. Versus Melatonin that just gives you, well, Melatonin.
For a basic stack(4-5 items you can take everyday), I would recommend Rhodiola Rosea + Low Dose L-tyrosine in the morning for Dopamine/Norepinephrine, Noopept + A Choline Source(CDP-Choline, Alpha-GPC, Choline itself etc.) in the morning for Acetylcholine and L-tryptophan at night for Serotonin and Melatonin. If you want you can also throw in a low dose dopaminergic stimulant like Caffeine. Just make sure to take it occasionally, to prevent tolerance. Only use it during times when you need a boost, like when you have a 48 hour assignment or something like that.
If you have the money you can also throw in L-theanine, great relaxant and antidepressant, but doesn't really give any benefits in terms of focus and energy. It can be used to treat anxiety and "smooth over" the jitteriness/anxiety that stimulants produce as side effects.
Noopept functions like racetams and their are many racetams, so if noopept isn't working for you, take a look at Piracetam, Aniracetam, Phenylpiracetam and the other racetams .
There are other herbs you can take as well like Gingko Biloba, Bacopa Monnieri and Lions Mane if you have the money, but in terms of focus/concentration and energy, I think the above supplements should give you plenty bang for your buck.
