I've used Manimal before - I agree some natural test boosters are crap, there's one famous one we refuse to stock because it's overpriced and doesn't work well (imho).
However, Manimal (from experience and based on the ingredient profile), is excellent. In the past when we were allowed to do it....it's the sort of product we'd have given out to someone to log. It's a "noticable" natural test booster. Your strength goes up, you feel a bit more alpha, and your recovery is slightly faster.
I've used it twice now, with the first time being in PCT and my strength actually went UP on it - it was the first time I pulled 260kg, so from then on I loved it haha! It's NOT going to pack on tons of weight (I've never bulked on the other hand, so probably a bad person to ask re: weight gain from the sup), but you will notice:
1) Better strength gains
2) Better mental state (you just feel more manly, for want of a better phrase)
3) Faster recovery
....which is all you can really hope for from a natural product.
In terms of the comments re: DAA, Bulbine etc. above, Manimal includes DAA (D-Aspartic Acid Calcium Chelate - same type as in Testforce), Bulbine, plus Fadogia Agrestis, shilajit (60%), Yohimbe HCL (99%) etc...so has those based covered.
Posted this in the other thread, but gives you a more independent review as obviously I'll appear biased:
