During your workout, did you notice any men of shorter stature with pointed shoes? Possibly pointed feet? It sounds like you’ve been visited by a gains goblin.
Do not fear, this can be resolved quite simply. Place 6 scoops of whey around your bed in a circle before you go to sleep. In the morning whichever scoop is empty will tell you the direction the goblin is coming and going from. On the 2nd night you must replace the missing whey with 3 scoops of preworkout topped with enough whey to mask the color of the pre. When the goblin goes to steal your whey he will overdose on the pre (gains goblins can only handle 2 scoops max)
After the goblin’s heart bursts, it is advisable to consume the corpse to regain any proteins he might have siphoned from you.
If you have any questions feel free to reach out. Ive handled my fair share of these buggers!
