The sticky white hot cocunut man pee that you shake from your bro's veiny tree of love and ingest as a hearty supplement to your daily calorie allowance.

I love the taste of Gary's Brotein, it gets me real pumped and is an essential ingredient in a Bromance.

Brotein Shake 

When you and your bro finish a hot sweaty gym session then trade blowjobs after the gym to release your tension. Added benefit of getting extra protein to fuel your muscle growth.

After the gym, my friend gave me a brotein shake straight from the tap. Delicious and my muscles are looking huge!
