Truly Potent Stuff!

Posted by Reviewer2091215 on Feb 21, 2014

I have tried this once since getting it. I took one pill in the morning, and being that I'm sensitive to stimulants, it really gave me palpitations, 1-2 loose bowels, and nausea for the first few hours. It was just too high a dose for me. But I'm thrilled that the label and reviews are true: "Tested for purity and potency." So, I have a pill cutter from CVS, and these pills split into quarters perfectly! Next I'll take just 1/4 of a pill and update this post as to how it works for me. I normally drink a medium Dunkin Donuts coffee to get going, but I needed a pill to get out of bed in the morning, and I want to cut back on calories and buying or making coffee. Plus I find coffee too stimulating and laxitative. And it's staining to the teeth! These caffeine pills are a nice alternative to theADHD stimulant medications I used to be prescribed, and way cheaper. Previously, I tried a CVS brand caffeine product at 200mg and it didn't do a thing. Then I tried another product, from a different brand that was offered at CVS, that was the green coffee bean, and it didn't do a thing, either. I wasted about $25 altogether! I knew I could trust iherb for caffeine that actually works. Thank you................UPDATE::: I tried 1/4 a pill to wake up, but it wasn't enough. 1/2 a pill is perfect for me! I have grogginess in the morning and keep hitting snooze, trying to wake up, but now after the alarm goes off, I take 1/2 pill (aka 100mg) and within about 10 minutes, my heart beats faster and the grogginess clears. My head clears and I feel alert, enough to get out of bed within 10 minutes. WHAT A GODSEND! I don't have the alertness to go grab coffee, so I have to take this. Thank you iherb and everyone who reviewed it! ..........NOTE: I have sleep apnea, I'm on some mental medications, and I get stressful dreams -- all of which contribute to the groggy mornings.
