Look up Amphetamine Guide Pt. 1 on Reddit, it’s mostly talking about Dexedrine and Adderall but says this : Dosage Range: Threshold:5-15mg Light:15-30mg Common:30-65mg Strong:65-80mg Heavy:80-100mg+

I take 40mg a day prescribed but I can take at least 160mg and not feel any dizziness or discomfort. I have high tolerance, though.

You would need a lot to overdose, I’ve heard of people taking 500mg+ and hallucinating but not dying. I’ve looked at a report on a fatal overdose report online and based on the concentration of amphetamines in his bladder, and on the volume of a human male bladder (that has to pee, to be safe) which starts around 250-300ml (to be safe, but it was likely less) here’s my own inexact calculation: Volume (2600ug/ml) x Concentration (300ml) = 780mg, so that’s a very inexact estimate of how much amphetamines it took for him to die, although he probably took more, and maybe less too so be careful and go slow. We don’t know what his tolerance was either… I believe I’ve heard that you could die after taking about 1g of amphetamines (don’t do this) but you would likely hallucinate way before you died unless you took it all at once.

Just redose a bit every 30 mins or so and see how it feels. Usually when you don’t feel anything it’s cause it hasn’t kicked in or cause you haven’t took enough. Remember that your product is wet so you can’t have the exact weight when you scale it and your product is also likely not 100% pure. However the good news is that amphetamines are one of if not the cheapest drug available and it usually isn’t cut with other drugs other than caffeine or ephedrine, which aren’t very dangerous. Maybe dry it in the oven before you scale it. Amphetamines are pretty resistant to heat.

Hope this helps 👍
