Agent Cool

Super Concentrate


Add your perfect level of cooling to any vape juice. Without losing flavor!

A 15ml bottle will last you a lifetime.

What's so special?

It's simple really! We combined three of the main cooling agents on the market in an effort to eliminate each of their individual drawbacks.

  1. WS-23: Nearly perfect on it's own, but doesn't provide cooling on exhale.
  2. Koolada: Gives you that cooling on exhale, but mutes flavor.
  3. Methyl Lactate: Offsets the muting caused by koolada and boosts that cooling on exhale, but very minty-tasting thus muddling flavor once again. 

So we trialed and tested with different ratios until we found the perfect blend that allows us to maximize our cooling without losing flavor. Our new agent cool is optimized for pods and nic salts, but works fantastic with e-juice as well.

This magical bottles makes all the TBD juices in my collection much more satisfying to vape! A must have in hour collection.


Agent Cool is an awesome addition to my TBD collection! Love it in my cucumber salts and I add it to Starbuck to kick the cooling up a notch. Doesn't seem to add or take away from the flavor at all, and with the dosage per pod being 1 drop (or 2 if you like it chilly), this bottle should last you a while :)

The Agent Cool Rocks!

I love this stuff.. Add a little to anything I'd like to get that "cool" tingle from.. Cucumber Breeze is my personal favorite to add to. I with the bottle could be worked so that adding drops works. The bottle's tends to add more of a flow of Agent Cool rather than drops which can take a little getting used to.

So cool!

Love this stuff! Just ordered another bottle or 2! I paired agent cool with the Blue Raspberry, perfect combination. This time I’m going to try it with the pear, I’ll let you know how great it is once I’ve tried it. 😊 I will never order juice from anywhere else.


I like a minthol on occasion and this works great. I use to add a minthol juice I have but that diluted the other flavors and was getting kinda old. One drop off this and a pod is good to go. Really like it with blue raspberry
