100mg 2FMA, 60mg 3FPM, 50mg 4FMPH... nothing?

Hi all, I'm new to RCs and nonprescription substances in general, but first off I want to mention that I am starting slow. :)

Here's the deal: I've always been a poor responder to any and every substance I've tried. With no tolerance, I:

• have been through dozens of prescription pain and psychiatric drug trials with my doctors. Nearly every single one gave no or poor effect, and often gave strange side effects. Apart from a couple oddball tropicals these were all oral.

• have to drink alcohol extremely fast to feel anything, and drink a very large amount to truly get drunk. I never get hangovers, and at worst have felt kind of cruddy the next midday but by then am over it. I can drink a third of a bottle of 95% Everclear in a night, no sweat - and did for several years just to get to sleep, before quitting. The only notable non-liver side effect was the caustic effect of the alcohol on my throat. The only reason I quit was because of that, and money.

• have virtually no reaction to marijuana. I am part of my state's comprehensive and well run marijuana program, and have given myself several trials here too. After a 3-4 month tolerance break, I was able to quickly titrate up to 1 gram of FECO/RSO extract oil, which gave very little effect and wore off after ~4 hours. As mentioned, I am no marijuana expert, but from what I've read and been told, doses of 0.05 grams of FECO/RSO is a strong dose for an average user. As another example, I had 100mg chocolates that could be split into 25mg squares. I could often take 1-3 100mg chocolates, while when I gave just one of the 25mg squares to an experienced friend they got stoned off their ass (I had to play trip anchor by text because they were having problems keeping their mouth closed when they wanted to close it). I always took marijuana orally in gelcaps, in food/candy edibles, or several different vaporizers, never smoked.

Now, for something on topic, I have had pretty much the same experience with RCs. I have no experience with stimulants beyond caffeine and ephedrine - both of which I barely feel, even at extremely high doses. My most promising RCs on hand at the moment are 2FMA, 3FPM, and 4FMPH, from a trusted vendor, in the hopes of finding a functional stimulant that will help me push through my constant pain and fatigue and get something done around the house.

As mentioned in the title, I have titrated up to 100mg of 2FMA, 60mg of 3FPM, and 50mg of 4FMPH, and all have given barely perceptible effects. I only experienced one odd side effect. Due to my ~15 years of pain I had gotten into the habit of never clenching my teeth, and instead I keep the neutral/resting position my jaw opened about half an inch. When sober, I still clench my jaw muscles, but at least I'm not loosening my teeth again. I think this has made the normal bruxism side effect turn into a severe case of Trump lip, as I feel only a little bit more clenchy in the jaw, but on 4FMPH and 2FMA I am constantly pursing my lips and sucking my teeth for no goddamn reason at all. This goes away normally, once the dose runs out.

So yeah, even for 'expert' high doses on these powerful chemicals (4FMPH in particular) I get nothing but a mild side effect. I forgot to mention my RC use has been all oral gelcaps or pellets. I have a good vaporizer I will try, but have never used it with powders. I'll also look up some insufflation guides, but I'm not a fan of going that route.

One other thing I forgot to mention, I am in poor shape generally, but my daily diet, hydration, and specifically my minerals and nutrients are squared away.

Has anyone ever heard of something like this? Certain people just not having any kick at all from psychoactives? Did they ever find any kind of root cause? What can I do with the other ~1.5g of these RCs as a test to see if I can get them to kick in? Why does this life suck so much?

Thanks for the advice!
