So in order to get this achievement you must craft the Beefy variant of a smoothie. In order to do this you must first complete the pond lab, at the end of this lab you'll end up in a bio dome which has 2 floors.

On the second floor, you'll notice a bunch of pink orbs growing along the sides of the bio dome wall. These are Muscle Sprouts and these are used to craft a beery variant.

Once acquired return to your smoothie station and scroll across to the recipes tab, you'll notice you can use grub goop as a base but now if you press LT or RT you'll be able to use the muscle sprouts instead. Craft 5 of your choice and then consume for the achievement.

Hope this helps clear up some confusion :)

You can look up a guide on the quest, it wasn't really that hard but you will need some water equipment. I made the beefy green machine smoothies(Sprout, clover, sprig). Make sure you have the items in your actual inventory and not a chest, might have been a bug but smoothies consumed that way didn't count for me. When you're in the smoothie station hit RB to the known recipes and make sure before you craft a smoothie you hit RT to change it to use the sprouts instead of grub goop.
