Hi Techlux,
You can take both of them together, they have no interactions or negative side effects. If you are a healthy individual, and eat enough greens and vegetables in your diet, a minimal amount of each can be taken. I personally take a single 100mg tablet of CoQ10 per day and about 150-300mg of ALA. You want to take it during the day when there will be the most oxidative stress occurring. At night, your body produces ample amount of melatonin which acts as a strong antioxidant and helps with body recovery.
I took a look at your stack, I would suggest reducing the amount of Ginkgo that you are taking to a maximum of about 120mg per day, even on days that you are studying hard. Gingko acts as a norepinephrine(NE) re-uptake inhibitor to a small degree, which is good to a certain extent for focusing and for motivation to study, but taking too much, or for too many consecutive days, will lead to NE receptor downregulation which will give you withdrawal apathy/lack of motivation.
Also for the aniracetam, the dosage that you have down seems alright, but I would start out with only the 2X400mg per day dosage that you have written. Remember; you don't want to feel "high" or overly euphoric when taking any of these substances, only calm and in control.
For DMAE, CDP-choline, citicholine, centrophenoxine, alpha-GPC, choline bitartrate, choline citrate, etc. they are all choline sources. You really only want to take one of them to prevent choline overload. If you take multiple, you will have to take very low dosage. Because choline citrate/bitartrate is the cheapest, I would stick with those. Take about 200-600mg of the choline citrate per day, divided into two doses, one in morning, the other in afternoon.
For vinpocetine, take only 5-10mg per day max. At that dosage, you get sufficient cerebral vasodilation to reach the threshold needed, and you reduce vinpocetine's side effect of acting as a Na channel blocker (reduces probability of neuron excitation and nerve conduction). At that low dosage combined with Gingko, you won't have to worry about the blood thinning issues of either (just don't take them before doing high intensity sports, as your blood pressure goes up alot during sports).
Instead of taking ALCAR, take the non-acetylated form (L-Carnitine L-Tartrate), and you will get the same energy boosting effects without its effects of boosting acetylcholine production (ACh acts on nicotinic ACh receptors as you mentioned). Take 200-1000mg, divided into 2 seperate doses morning and afternoon.
For sports, and before tests, take a dose (2.5-5 grams) of creatine, which helps in the generation of "Burst Energy" as I call it, which is good for high intensity exercise and for cram sessions/high intensity test taking periods.
Tyrosine is one of the more tricky supplements. Taking too much for too long can lead to down-regulation of dopamine, norepinephrine and epinephrine receptors as tyrosine boosts these neurotransmitters. Further, chronic long term use can lead to burnout as it is boosting your response to stress. The boost in stress response can be positive in the short term to motivate and get things done, but downregulation and inability to recuperate from stress because your body want to continue working hard when taking tyrosine can, in the long term, lead to rebound depression, anhedonia, apathy, etc. which is only transient (will go away within a week or so after stopping the tyrosine). If you desire trying it out, take a low dose of 200-1000mg per day, and not for more than 3-5 days strait, with plenty of days break in between to let your body homeostatically re-adjust itself back to normal.
And I would recommend against taking noopept. You can try it out, but for most of the people that I know who have taken it, it reduced short term memory and reduced ability to concentrate (for me my mind was making connections to random things related to what I was trying to study, which was unproductive and very distractable).
