Unived Natural Caffeine L-Theanine Capsules (100mg/200mg), for Energy & Focus, Nootropic, 60 Vegan Capsules

Brilliant product. No crashes. Clean energy !

Good for stimulation but lot of side effects after few hours of consumption. Like cosiderable pain in liver area.I think it's because of green tea extract they used which is widely known for liver damage. Anyway used few and rest I throw it away after continuous side effects. grean tea extract is pretty dangerous form of l theanine.

Been using for a week and I started noticing blood in my stool, usually this happens when I use sub par caffeine products. I’ll shift back to muscle tech caffeine as I don’t seem to be having any such affects.

Works.but do not consume more than two at all at any cost because it makes us dizzy and sleepy+ severe headaches!It's very powerful supplement!

Really does work. No jitters. May cause stomach upset sometimes. Do not consume on empty stomach.

When I started taking it, for the first two or three days, I felt good, energy came immediately, but after a few days something, three days later, I started seeing some severe adverse effects like my urine output had increased so that cause hypotension, and due to this I was also having problems of constipation so I stopped this

This product gives you solid kick and you can literally kill your workout ! Excellent product, go for it !Caution : Please avoid if you are a beginner, you may not handle it well period

good
