"This is very strong! I accidently had 2 teaspoons of the stuff before realising I should of had 1/16th. I was shaking like hell, came out in blotches and pretty much lay away feeling anxious and on edge for the next 10 hours. My own fault! It definately works though I will be more careful on my next dosage!"

"Take note of the dosage instructions, very very strong, first time I took this product I was up all night shaking, learnt from my mistake. Excellent product, used it while training for a marathon, gave me that extra boost...plus more"

I would like to echo the sentiments of Sean Wilkes. I few months ago I made exactly the same mistake. Its very easily done. This product should come with an unmissable BEWARE or CAUTION sign. I too ended up in hospital needing a Cardiogram having suffered from Tachycardia and Caffeine poisoning. My consultant said that my 25 years of regular intense exercise probably saved my life. A heart rate of 180+ for a 2.5 hour period left me in quite a bad way and would almost certainly have brought on a cardiac arrest or at least an MI. 5 days later when I was finally able to get out of bed I binned the entire sack and will not be buying it again. Myprotein products are brilliant and the service is equally good BUT someone will end up dead if this product continues to sell in its current form.!!!

"I just have to add that although this product is exactly what it says it is (a decent stimulant without being too speedy) that the taste isn't what I would describe as moderatley bad, it is seriously bad, like chewing a paracetamol bad. Not 3*, 1* for sure. I do not mind 99% of stuff, I actually enjoy whey protein and I can hardly even taste creatine, I've ingested ... ""other"" stimulants which may taste bad but I can tollerate them. Not this - I mixed it into a mocha and ruined it, I tried to drink it in a normal size cup of water... bad idea. Get this down you as fast as you possibly can and have a water to hand to rinse it down - I'll be buying the capsules next time, failing that I'd have to sit making bombs with rizla, but for now I'm going to finish off this pouch by mixing it into a small amount of water then immediately chasing it with clean water. But to actually review the product... does what it is supposed to, and found it a great help on days when I'm going for a 1-3RM max especially, though only used the product for 2 weeks so need to give it more time to decide if it will be a permanent addition."

"i add this to a pre workout shake, with Raspberry Ketones Powder, BCAA powder, creatine mono-hydrate powder, greentea extract powder,Acetyl L Carnitine and 1/4 vitamin b6 tablet (bought from ebay thinking it was powder, 1000mg tablet so too much for my needs) with water. really boosts met rate . this powder and indeed mix is very powerful be very very careful with dosages always follow advice on packaging from this site, more so with this product than others. Do not take a good few hours before you expect to get to sleep, cause that just is not going to happen. Raspberry Ketones may give you a nice tasting little burp now and then, at least you will know they are doing their job, lol. you may get a little dizzy if so use a little less till you get used to this combo, you will burn fat and get clean gains big time tho. bhmoomoo"
