Carlyle Guarana Extract Capsules | 200 Count | Naturally Occurring Caffeine Supplement | Non-GMO, Gluten Free

I used to take thermogenics until I started taking these. They are perfect for energy and appetite control. You don't feel jittery from the caffeine at all, just a constant flow of energy. I love them, I'm on my 2nd bottle!

I could tell a difference after twenty minutes of taking this. It’s a higher dose, but just PERFECT for my needs. It did not give me jitters, or make me hyper. Basically, it made me feel awake and effortless. It took away the sluggish, “no energy” feeling all day. I am focused, and got tasks done that I started around the house. I definitely recommend it. Do your research re: dosing, as there are various strengths.

no problems with the product or the shipping - thank you

es bueno, pero su efecto no es muy duradero

Good price

To clarify for this product, these pills are a 400mg mixture of processed 1600mg of Guarana extract. I don't know what they took out, or what they kept. The Straight.com review of this product lists: "Pros Provides a natural energy boost Made with high-quality, pure ingredients Contains antioxidant properties" and cautions against irritability. This review fits, and I believe, then, that this is more of a cheaper caffeine product. If you are the Guarana + nootropic type, I wouldn't recommend this.

Excellent source of natural caffeine. Doesn't over stimulate. Great price Good value Recommended

FAST SHIPS. GREAT PRICE. WILL PURCHASE AGAIN.

I like the product is very good antiossidanti

Excellent produit. 1 seul comprimé et je me sent apres 20 minutes plus productif, réveillé et plus concentré et ce meme apres 12 heures apres l'absorption. Aucun effet stressant. Me sent plus allumé, moins paresseux et agit longtemps. Tres heureux de mon achat.

Muy útil para sentirme con más vigor.

Me gusta por la energía que te da….

Don't feel or see any effect... Like taking nothing... Very disappointed
