I think its worth it. If your not on AAS at the moment, why not throw in a little slin? I like to give my body every advantage it can get..the gains obviously wont be as great as they would be on AAS, but they will still be decent. You should be able to get 3-5lbs of muscle in 4 weeks on a slin only cycle..that sounds pretty darn good to me!..And for $20, you can buy enough slin to last you a year!
