A Priori: Muscletech sent me a bottle as a promotion. That being said, I received a bottle of Iovate's "True Grit" booster. The formulae are comparable.: they are basically herbal, or mineral based. There is little in the realm of bizarre, laboratory experiment compounds with long acronyms that require you to cycle on and off like a crack-head. The effects are good. This product helps to regulate the hormones. For me, who works a stressful job (physically demanding) and has a pretty solid workout regimen, this is valuable. Due to the demands I put on my body, the anti-cortisol agents are great. It prevents the kind of sluggish, effeminate droop you get when you've drained yourself too much. Beyond that, I did increase a slight strength boost. I am not certain that the boost in strength gain is the compound, so much as that it allowed my body to regenerate better in order to accommodate basic strength gains. It is not a steroid, do not expect miracle gains, but it does take the edge off. If you can afford it, you can do worse - just like with multivitamins.
Please note, that this calculator predicts your maximum possible natural weight, key of course is which definition of natural I am using. In the context of this prediction calculator, “natural” means no steroids, no pro-hormone supplements, no hormone replacement therapy, and no testosterone boosters – that is, no products that artificially raise testosterone levels. I realize that this is a very, very loose definition of natural and its one that personally I don’t agree with. If you use every product that GNC has to offer that doesn’t boost testosterone, I would consider you natural and the predictions of this calculator would be applicable to you.
