Is 3-FPO worth it + my limited experience with stims (which I still don't understand)

Hi, I was thinking about getting some 3-FPO. I've never had proper stims, amphetamine isn't easy to get where I live. Right now I have thozalinone, PPAP and phenylpiracetam and I don't understand if they're just bunk/weak or I'm not much sensible to stims (or maybe what people call stimulation is something very different from what I expect).

I've tried up to 100mg of PPAP with a hefty cup of coffee or 250mg thozalinone with 30mg PPAP and I didn't feel much. I could notice I was altered but I couldn't properly identify the effects. The thing I noticed the most was that it made me zone out more frequently, like I was thinking about everything and nothing at the same time. I wouldn't call that being more focused or more motivated and I'm still a procrastinating unproductive idiot. I still don't get stims.

Sorry for the digression, I'm hoping someone can help me, like comparing 3-FPO to those substances or tell me if it could be worth it anyways (or if anyone has experienced toxicity idk). Any experience?

Also, I'd be glad to hear other people's opinion about my strange experience with stims in general
