I certainly believe they are.
When I take Carbolin 19 I find that my appetite is increased. Sort of a synergistic effect with respect to bulking.
Alpha Male is harder for me to judge. I am certainly getting old enough where a bit of T boost should be possible. I haven't done blood tests to confirm it or anything though.
I'd say try it. Some people find the effect noticeable, though I rarely do for any supplement. I'm surprised that I get noticeably hungrier on Carbolin 19!
