Seems Ok, but not sure about it's absorbency and/or effectiveness
Verified Purchase
As a person that 1 espresso makes him 'jumpy' and alert, and since espresso has about 40mg of caffeine, this 100mg should be plenty, but it doesn't do much more than 1 espresso cup which is weird since it's double the amount of caffeine. but maybe it's the Theanine inside that's 'controlling' the outcome. Anyway, Surely not a bad product, but not extraordinary. ok for the price.

A cost-effective and efficient way of taking the medicine.
Verified Purchase
Take 1-2 capsules daily, avoiding times too close to meals, as this may interfere with calcium absorption. Remember the recommended frequency: take a 2-day break every 5 days to avoid caffeine addiction. The quality, packaging, and effectiveness are good. The capsules have no special taste.

I recently started taking TransformHQ Essentials with caffeine and L-theanine, and I wanted to share my experience. There are 180 capsules in the package, making it a pretty good value for the price. At first, I was a little wary of the caffeine, as I have a sensitivity to it. However, the combination of caffeine and L-theanine has proven to be quite successful. I noticed a boost in energy, but without the usual jittery or anxious feeling that caffeine alone sometimes causes. L-theanine actually helps soften the effects of caffeine, providing a smoother and more sustained energy level. The capsules are easy to swallow, and I appreciate that they contain no artificial additives. I typically take one capsule in the morning before a workout and one mid-afternoon when I feel my energy starting to drop. This helps me stay focused and productive throughout the day. I've also noticed an improvement in my overall well-being. My stress levels are lower, and my concentration is better. This is especially important for me, as I often work on several projects simultaneously. The only thing to keep in mind is individual reactions to caffeine. While I haven't had any side effects, I recommend starting with a lower dose if you're not accustomed to caffeine. Overall, I'm very pleased with TransformHQ Essentials with Caffeine and L-Theanine. It's a great supplement for anyone looking for a way to boost energy and improve focus without unwanted side effects. I highly recommend giving it a try!

I used to take caffeine tablets and they worked well, but after the effect wore off, I felt a rebound effect. I heard that adding theanine can alleviate this fatigue rebound, so I bought one to try.

The perfect combination for energy without stress
Verified Purchase
Caffeine with L-theanine is a classic productivity supplement. Caffeine gives you energy, while theanine soothes jitters and improves concentration. The capsules are medium-sized and easy to swallow. I take them in the morning and feel alert and focused all day, without the "coffee jitters." The package contains 180 capsules—enough for six months! TransformHQ has created a great product for work and study.

Excellent!
Verified Purchase
Good quality, works. The main thing is to start with a small dosage. I took it at the end of a strength training session for faster energy recovery. The result, energy, training frequency, sleep pattern improved. This is where I found the ingredient that suits me. The packaging is good, the size is adequate. The advantage is the composition and neutral taste of the capsule.
