RE: "Identify the molecule" league #20. Prize: knowledge + 5 Hive + 100 STEM + 200 TMN

"β-Endorphin"
you're right.

Even though the user professorbromide was faster a little,
I guess it's fair to provide the bonus to you as well.
'cause you provide even more precise answer - β-Endorphin.

so, congrats!

just sent you 100 STEM and 5 Hive

and if you want to get 200 TMN (TranslateMe Network token) (NEO-based)

https://coinmarketcap.com/currencies/translateme-network-token/

you need to provide me here in the comments section your
NEO-address (it's not recommended to give the one from exchanges).
It's highly recommended to get O3 wallet.
if you don't have it, you can follow my little guide on how to create the one (it should take just a couple of minutes).
