We used to get eca here but not for a long while, ephedrine is fantastic, I have used liquid ephedrine in the states.
There were and are injectable ephedrine amps but I never got to try it. I doubt it would hit better than oral but would have liked to try just for the novelty. The meth trade put such heavy restrictions on it that it's very hard to come by now. For a while there were these crude Pakistani 30mg pills which I ordered from the UK, but this was like 15 years ago. Before that there were Spanish and Turkish 50mg pills. My first ephedrine was Dymetadrine which my cousin picked up for me from a Venice CA supp shop in like 1995

I know you're in Ireland but I know at least in the UK you can get "everything" it seems to me. My UK ephedrine source also carried Ritalin at the time and that is much better than ephedrine of course. I'd argue a clean but strong stim, in reasonable therapeutic doses, isn't any more dangerous for your health than high doses of caffeine.
Citrulline works well with a single cup of filter (5g citrulline in a separate kool aid like drink (Isotonic Game Cherry Berry)), like super actual proper well. Next step is adding Arginine and Beta Alanine (I have beetroot powder and should kinda do that as well but it is gross)
Sorry for the peanut gallery comment - but I do stand by the above in terms of increasing workout intensity.
I believe in your experience but I don't get any nervous system effects from citrulline or arginine so they don't enhance 'intensity' so to speak, at least not for me. They aren't supposed to be stimulatory in any way. A 3-5 gram dose of tyrosine otoh does have effects, especially if combined with stims. Lots of people have come to associate the itchiness of beta-alanine with getting "up" for workouts but I think it's just psychological conditioning due to it being paired with caffeine. you feel the itch and now it's time to workout. You could make a similar association with a smell, sound or even a color too IMO. Ever notice how stim caps are often red and supps for sleep are blue?
