You can get some TStrat from here: https://faucet.stratisplatform.com/

It might be a bit a boring to get a significant amount from there, and sometimes the faucet isn't running, in which case your best bet is to join the Discord (if you're not there already) - https://discord.gg/9tDyfZs and get some directly from the team. If you let me know your username I can give you a role to bypass the modbot, that way you don't have to jump through the hoops and can dive straight in.
