should bring your own tbh. I've been in the situation of traveling from austria to czech republic and back, carrying drugs for personal use, pretty often myself and nothing ever went wrong when taking a train directly to wien hbf, meidling or floridsdorf.
if you're uncomfortable with that, you could've ordered smth from any austria/eu vendor, with tracking, to a viennese post office using the "postlagernd" service, I believe they send it back if you didn't pick it up 14d after arrival.
didn't think of any of that?
your problem.
personally I wouldn't buy speed, or any chemical drug for that matter, off the streets of vienna, since you'll just get unbelievably shitty quality at a price well above whatever you'd have payed your average vendor even when including tracked shipping, crypto exchange/transaction fees and the 1eur you pay for a "postlagernd" letter. the best thing calling itself speed, that I've ever gotten from a street dealer in vienna, was like 35% pure amphetamine, which I payed 15eur/g for...
now I get 74% pure and dry speed from drugmax on abacus for 4eur/g, so the actual cost for me is just 5.18eur/g, since I usually just get 1dag of it with every of my orders (hmu if you're interested in my calculations). if you were to buy his speed only + his eu-tracking option, you'd still end up with a total cost of sub 70eur for 1dag.
so tldr:
not worth it. either take some of yours on the trip or order smth to the place you're staying in advance next time

It is however a little more expensive than the one you recommended, but that also depends on quantity.
