I’m not sure how much I will be adding to the discussion.. alas
Stimulants need to be used regimentally if using daily, better yet to take time of if you can manage to, but fine if not:
Clinical Methamphetamine I believe is used at a maximum of 25mg pure Dextro Isomer Daily. This may be the amount studied that doesn’t not present neurotoxicity etc.
I don’t have any evidence for this statement, but I believe many are preconditioned to believe is many pegs higher than any other stimulants in damage.
There may be data regarding its neurotoxicity, the sertotonin affinity, and the clear fact that used above a threshold provides very compulsive and addictive effects.
But I’m not so sure in saying far beyond Amphetamine, MDMA/MDA, Cocaine and Cathiones, just a few important factors to consider,
If I was you, my only concern would mainly be the quality of what I was using, and also to bear in mind Methamphetamine has a established potency exceeding Amphetamine and is far more Soluble in the brain (I can’t spell Liphophillic or whatever it is)
Leading to the longer duration, potency and also observed neurotoxicity when heavily abused- my point here also remembering this is abusive high doses, no sleep, no self care, no food, etc. it has proven efficacy in medical use.
Of course yours won’t be “official” and that’s the gamble you take.
I would Volumetrically dose or capsule maximum 30mg to account for the unknown strength of product or if it is racemic.
I would dose only once in the morning, if not only a couple hours after if needing longer cover, say 7am and 9am if one dose doesn’t last all day. And this must only be in the safe range.
Going beyond risks all the utility in the first place.
You need to exercise, walking and weights is best bang for buck. Nothing crazy but 10,000 steps 3x a week, and 2 30 min full body work outs will suffice.
Protein every meal, sensible carbs and fats, fruits and veggies. If you struggle to eat healthy and it’s not a appetite issue then you can supplement but it’s not a excuse to avoid all whole and quality foods.
From the dosing regimen, I could be wrong as I can’t think of methamphetamines half life, but if possible to allow it to clear overnight as you sleep, as this will ensure your receptors, monamines etc has a chance to clear, repair and rest.
I’d also recommend very specific potent antioxidants/other helpers that don’t have issues like NAC- it’s a god send but it takes baby sitting.
These being
Benfotiamine
Tocotrienols
Taurine
Creatine
Astaxanthin
Magnesium L Theronate
Vitamin D3 in the 2000IU range
Vitamin K2
Lmethylfolate
I can do a write up but these have specifity in assisting what may come as the toll of chronic stimulant use at medical doses.
Lastly sleep, it beats everything, but making it as good as possible and quality will help everything else, my Methylphenidate is a different drug depending on how well I’ve slept.
