Friend said this is effective - other than that I cannot offer more details. There's not a lot of choice for a caffeine-only supplement on iHerb. If this review was helpful to you, please click YES below - thank you. For reviews of all the products I have purchased from iHerb, please click my username above.

Truly Potent Stuff!

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.

Gives some good energy during workout! Only some trembling in the first 20minuits after taking it!

Fed up with drinking many many cups of coffee before workouts, I tried to take caffeine directly as tablets. Primaforce beautifully delivers what's expected.
