I did, and it also put three inches on my penis.
As a serious answer, nothing will do any of that. Blasting a gram of test a day won't do that.
It probably helps marginally (never seen any studies on it, and they probably don't exist either), but nowhere near what is claimed. Supplement companies make money off of over hyping something that at best adds 1% to your gains, which if you are Stan Efferding and have the money to buy your own hyperbaric sleep chamber then it makes sense to get the best. If not, then after a decent protein, creatine, and fish oil spending some quality time at a sauna or getting deep tissue massages are much better uses of your money for cost:reward. Or, you know, taking some test and SERMs for the same cost of some supplements.
