Hi Poison I've used it in the past and enjoyed it. I used it primarily during my night workouts, since the stims weren't overbearing I was able to get in my workout and fall asleep on schedule. I was never critical of the product, in fact I think it's the best PWO to be used for nightly workouts.
Having tried many different PWO's I've come to conclusion that none are going to drastically change the way you perform in the gym, occasionally I saw some PR's, but I attribute any gains to my diet and training program remaining consistent. I'm not the type to support a product if it doesn't live up to marketing claims. I understand that it's a business and as such you have to move product to be successful, but I despise companies that make wild claims, with no hint of science to backup those claims, apart from abstract studies, since again none of us (consumers) are privy to dosages. I made a conscious decision to support companies that dose their products correctly and according to clinical studies, in that regard APS and Driven Sports have been getting my business lately. This industry is plagued with wild claims and under-dosed products that do more to financially benefit companies, at the expense of their consumers, just my 2 cents. But I do believe ASGT belongs among the top in this category.
