1.M.R Vortex Pre Workout Powder – High Stim Preworkout for Men & Women with Glycerol, Caffeine, Niacin, and Herbal Extracts – Energy, Focus & Endurance – Power Juice – 50 Servings

I needed a break from aminos so I picked up the vortex. What do I think ? It does jazz you up mentally however, the original formula was perfect. Why mess with something that works ? I miss the original 😢. With that said, in 2024, this formula does its job. 50 servings, that's never changed. It's very productive to a extra serving count beyond 30. I've used this many mega years for running in the hot Summer heat and found vortex most beneficial in extreme conditions such as July/August summer days. For me, it's important a pre workout primary function supports concentration, mental aspects. If your mental faculties are in check, you can accomplish anything 😀 [vitality]

This stuff is amazing! I have a high tolerance for preworkouts and have a hard time finding one that is affordable, tastes great, and gives me the energy to push through early morning workouts. This one checks all the boxes. I use 2 scoops about 15 min prior to working out and I can feel when it starts kicking in. I also love that it doesn’t give me any crashes when it wears off. Will definitely purchase again.

The product, at first, was extremely potent. I have an extremely high natural caffeine tolerance (Not joking, red-line energy drinks barely affect me), and quickly develop tolerances to herbals and other non-extreme, non-chemical, and non-harmful stimulants, so this review MUST BE TAKEN IN LIGHT OF THE AFOREMENTIONED FACT. I like this product because it is CLEAN. My body is not left with detrimental substances in it after using this product, and one or two scoops later (not three... or four... or five...) I can feel a moderate energy boost characterized by increased endurance as opposed to hyper-stimulated biological desperation mechanisms, such as those induced by chemical-based stimulants like NOExplode (which gives me such a terrible headache...). I DID buy this for weightlifting (its designated purpose), and it DOES provide a noticeable energy boost. Caffeine, as it were, is an empty energy, but the herbals in this product are a relatively good moderator and provide a subsistent increase in strength. This product is, literally, caffeine and herbals. That's why I bought it and I am NOT disappointed. All in all (to use a druidic axiom) it is, indeed, a great product for a few simple reasons; It is Clean (no headache, no poisonous effect), it Does work (a moderate, 7/10 energy. And do you really WANT to feel like you just ate Meth? If so, then you might at well just go ahead and...), and it tastes GREAT (I just eat the powder straight. It doesn't stir well well in water; You have to shake it in a bottle. But the powder is quite edible; It's like Kool-Aid without the bitterness). It's a great product. If you're looking for something super methy, look elsewhere. If you're looking for something you can use Sustainably and Consistently, here you are. I might not recommend using it every day, but if you use it consistently you're not looking at long-term health effects unless you eat a LOT of it EVERY day for Months. But that's caffeine for you.

I really like this pre-workout. For the price you can't get a better deal at GMC or any place else and I can also vouch that this is an approved supplement according to NCAA and US Army standards. I have taken multiple drug tests as I am a part of the military and never failed a test yet. This is a worry free product you can use before PT or before heading to the gym to lift and it doesn't leave me jittery or burnt out after use either. I do recommend that you use this no more than two weeks straight at a time as you can build up a caffeine tolerance to it and it becomes less effective. The taste is pleasant and sometimes I even mix it with the BPI creatine supplement before going to the gym and it too is also a great product for less money. 10/10 would buy again for myself or a battle buddy

2.5 stars. I have been buying BPI for years and never stray away as I know it’s effective for me, affordable and the taste is pretty decent. I normally order directly through their website but in a pinch I ordered here on Amazon. The container size was different but no biggie maybe they just changed it. The flavor also tasted a little different to me as well. The big issue is that multiple times now I have broken out in a full body itchy red rash after taking this product (the one purchased from Amazon). It starts to go away after about 30 minutes. For years I have never experienced this before and not sure why all the sudden I’m having negative side effects. It doesn’t happen everyday but once in a while. This product has been the only thing I consumed before breaking out in the rash. That being said, I won’t be re purchasing this product through Amazon again and will have to make note of side effects from products purchased through their website.

This stuff is great, it really maximizes how you workout, and it gives you that extra kick you need. THIS STUFF ACTUALLY WORKS! But more importantly, the reason why I'm writing this review is because of the following, READ THE RECOMMENDATION. I don't care how big you are, our body will have a negative affect if our take 2 scoops for your first time using it. I'm 6'3" 235 Ibs and I thought to myself "well I generally take more than I'm supposed so this'll be fine" and 40 minutes into my workout I yakked up my lunch I had 2 hours ago. TAKE THE RECOMMENDATION. Your body will not be used to it at first. So please just go with one scoop your first time, trust me.

They taste okay. Works fine before workouts. Even though the size was mentioned, I had no idea it would be that small. So after all, it’s a bit expensive for what it is

Thia thing came openee, not sealed and powder all over the delivery bag. Tried to retuen but it says no return policiy...very bad never again

Worst pre ever. Tastes like ****. Also, the prpduct was open and leaking when it reached me and Amazon won't return it.
