I have both in authentic Russian pill version but have only tried each separately. Seeing as I want to maximize the efficacy while minimizing cost, I am interested in mixing both.
I've used Phenylpiracetam on top of my daily alcar+gpc+tyrosine+ciltep+creatine+dha+methylb12 stack for about 5 days with great success in terms of vitality, focus and stamina (for study and workout purposes.) Insofar as Phenyl. vs Pram + Ani + Sulb + Tau goes, I'd have to go with the former in terms of efficacy overall, although I may be biased since I find encapsulating a daunting task. I've yet to to mix the Phenyl. with my mentioned racetam stack (could be fun.) So far I've concluded that Pram+Ani+Sulb+Tau does not yield an effect proportionate to its price as opposed to just ordering a 30 pack of phenylpiracetam for $35 and having a month supply on the racetam side. (I order through a colleague in NY so I don't know where he gets it.)
Couple notes: ALCAR+GPC+Tyrosine+CILTEP+Phenyl.+caffeine mixes wonderfully! If you're looking for a better adderall substitute (in terms of focus only, not "motivation"-- for that, I reason, you have to have good enough stimuli;) In general, this is as closest as I've come after much undue expansion of resources (lol.) My understanding is that most of the stuff mentioned is generally harmless and is a nutrient (for Alcar see age-dependent dose recommendations. I also chose not to supplement with ALA.) What I'll probably do is continue taking everything above and just cap TAU to mix with my DHA+GPC and entirely disregard little researched Pram (never tasted/smelt anything worse) Aniracetam and Sulbutiamine. What I'll do instead is get a B-complex and mix that with my Methylcobalamin B12 to essentially recreate my own "Sulbutiamine" and get some caffeine pills. At that point I should close to approaching a "5hr energy" recipe.
Currently, I am in my 2nd day of testing Noopept entirely alone. And, incidentally, it's the 2nd day I've been getting strange (tension?) headaches towards the top rear part of my head. I am not on anything but creatine, DHA, Vit D and Noopept right now so I have to rule out "choline induced tension" (never even had that) and I never get creatine headaches. I've never experienced this, save for the time I dosed too much Adderall with Pram and Tyrosine (lol.) I am going to take Noopept for one more day probably but will discontinue if headaches persist as my semester is coming to an end and I need to have my shit together. Anyway, if Noopept works out for me, I will then mix both Phenylpiracetam + Noopept and report back. My question is to people who have tried mixing these chemicals or to anyone with appropriate education who can see any potential contraindications.
Edit: I couldn't bare the noopept headache so I took like 1.5grams of my prop mix of Alcar + GPC + Tyrosine, hoping the tension goes away. I am disappointed I can't even trial this without needing something else. (I took this because I've read the choline helps.)
