I think spitting is one of the nastiest habits around. Some guys seem to think it makes them look masculine when all it does is make them look repulsive. Besides looking bad, it spreads germs.
I suppose this would depend upon whether you need the extra protein, or not.
Spitting...
Just dont do it at all! Haha. Thats nasty
Swallow...it's easy clean up.
Ok I say spitting for-sure!! But if you want to try and swallowing it go for it and see if you like it ! That way you will know your self which you prefer
Swallowing is healthier
