creatine and a good nutrition shake/protein powder. when i was a kid, GNC brand and Twinlab made a medium dose protein/vitamin/mineral/sometimes creatine mix. worked well for me, along with Phosphagen creatine drinks (the fruity kind). then in my upper teens, i took Phosphagain and a few other EAS supplements...then Muscletek. They worked, esp when i had cascading hormones at that age.

(Wish i had never tried Andro products. Muscletek had some very effective ones, but those should NOT have be used by anyone in their teens/early 20s. im probably worse off by using those...people in their teens and early 20s should not be supplementing with hormones or prohormones. ).
