The FitFrek Score reflects overall experience — not just how strong it feels.
Edge of Insanity makes its intentions clear from the first scoop. The yohimbine hits fast, the focus is real, and the intensity is not something you ease into.
Bottom line: exceptional for experienced users chasing intensity. Not for beginners or anyone sensitive to stimulants.
Energy window is around two hours. Taste is rough and you can smell the compounds, but nobody buying this cares about taste.

Learn moreVery controlled energy and focus. I experienced a lot of drive and focus. Made me want to kill the weights. ?
Pump wasn’t too noticeable but endurance focus and drive definitely made up for it. I strongly recommend this for a daily stim that will get you going.
It hits after about 15 minutes and makes you a beast with the weights. I’ve noticed the focus lasts a nice while. About maybe 6 hours for me. The pre itself lasts about 30 minutes - 1 hour. Doesn’t last too long with me. A must try for all the stim junkies looking for new powerful stuns to try to get that high only stims can get. Endurance was crazy as well. Was a crazy fun stim and to wrap this up the main positives are the endurance, focus, drive, and energy.

Learn moreEdge of insanity is one of those pre workouts that you either love or hate. It’s got a good amount of alpha yo in it, so if you’re sensitive at all to this ingredient, it might not be for you. For the alpha yo peeps, you’ll love this one for sure. For me, I’ve taken this numerous times and I either have a great workout, or I’ll get the bad alpha yo sides, like super high heart rate, cold sweats, just the feeling of being sick, which ruins my workout. But there’s also times that I feel great, even euphoric, while running it. It’s really weird. I don’t have the greatest alpha yo tolerance so that’s probably why. If you’re worried about flavor, psycho pharm has the best tasting Pres in the game so whatever flavor you choose , you can’t go wrong. As far as pumps, they’re actually not too bad on this. It’s a good pre to try, but start with half a scoop for sure

Learn moreThe effects kicked in within 10 minutes, I felt moderate beta tingles and then throughout the first hour the alpha yo effects such as fight or flight and nose drip occurred.
I have gone through a lot of flavours of this product and all are perfect, possibly the best in the industry.
Overall the energy lasted around four hours and there was not a large crash, I found it to be great for any workout but not cardio at a full scoop as it impacts breathing too much.
This is a very popular product and quite versatile as you can stack a third or half scoop to many pre workouts as it has some of the purest yo in the pre workout realm.
I would say half of this with half of a focus hitter pre workout is a good option!
I like the product but think in the focus department it's very lacking..
