Pure Caffeine Tablets 200mg - 120 Tablets - Pre Workout, Energy Boost - Made in The UK by Innopure

These are the cheapest caffeine tablets I've found online, I've previously bought caffeine powder & weighed it out with miligram scales so although I've not tested this under lab conditions I can say from experience that anecdotally the effect is exactly what I'd expect from ~200mg caffeine anhydrous. These are best swallowed whole, but if you want/need a quicker rush & suck them till they dissolve or crunch them up they have the characteristic bitter caffeine taste (and also quite chalky, due to the binders etc - Pro-Plus contain sweeteners so these have a different taste from those, if you're used to crunching those up).Worth noting that pure caffeine in supplement form is much more potent than from coffee & can give you quite an intense 'come up' rush, so if you've only ever previously drank coffee I'd suggest cutting one of these in half with a sharp knife & trying 100mg first then taking the other half 30-60mins later if 100mg doesn't make you too hyper etc.If you're looking for some L-Theanine to combine them with as a nootropic these are the best value I found online:  Premium Grade L-Theanine Super Strength Capsules - UK Manufactured Lab Tested - Non-GMO & Gluten Free - Easy Swallow L Theanine 200mg Powder Capsules, Made In UK

I’ve always studied better at night. And I’ve been taking these tablets to help me pull all-nighters to study for my degree, and can honestly say they work really well. I’m alert all night, and can stay focused for ages. I do however, drink one cup of coffee after taking the tablet.. I’m not a health expert so don’t kick me for it! But have really seen a noticeable change in my concentration levels. Also, I take these before I go to the gym too, and I’ve noticed that I can run on the treadmill for over an hour without feeling like I’m completely pushing myself. So yeah they’re good

Does what is says; I had to go off coffee for medical reasons for about a month and as an avid "2-cup a day'er" I was worried about headaches from caffeine withdrawal but one of these tablets in the morning and it worked like a treat. It's not a noticeable "kick" which I like (as I was slightly concerned that's what it would be like), but it's not. Great product.

This product works well to help me get perky in the morning since some night time meds sometimes leave me dragging a bit. The product seems to work gently (rather than "jolting") and effectively to help me get more alert. So, I'm pleased with the purchase. I had planned to cut the pills in half and may yet do that if I can find a pill cutter. The outside casing of the pills is hard enough that the pills don't cut easily with a sharp knife on a cutting board. But, no worries, they work fine just the way they are.

its a very good product that gives me more energy when I work out on the gym. I took 1 tablet from 7am in the morning and Felt wide awake the whole day. The down side is I was not able to sleep at night. I might have to take half the tablet only. Over all very good

I don't know how comfortable I am with taking supplements as strong as this, but was in desperate need for something to keep me awake during lectures. Just one did the trick, didn't get the jitters and stayed nice and awake for the rest of the day.

Good boost of energy and awareness. I use them pre workout / if I'm feeling tired, and they give you a real kick! Don't take after 16:00 or you won't sleep (learnt from bitter experience). 4 stars rather than 5, as they're a bit chalky in the mouth

I tried many different caffeine pills especially during my cuts. I took whole month off from caffeine before starting my cut this year. I'm not a coffee drinker. I tried this pills and unfortunately they are not working well for me. I ended up taking two pills and two red bulls to feel any effect. Overall it is a good product and it is very cheap. Unfortunately did not deliver for me. I won't buy it again.
