I’ve used Dren twice now. One pill lasts a very long time… something like 10 hours. It puts me in a really good mood and definitely makes me want to run around the block a few times. I also notice I become a lot less hungry when I take it because of the 5-HTP.

The only downsides about it, in my opinion, are that you can’t take it too late in the day or you won’t be able to sleep because you can’t control the dosage like less powerful fat burner energizers that require taking a few capsules at once. The other downside I noticed is that if you take it for too many days consecutively it starts to wear off. I think it’s best used only on cardio days - I didn’t like using it on weight days because it made me feel too overstimulated.

I'd like to hear what other people think who have used it and if they get the same experience?
