Hi, i’ve just tried my CTTM and IShine, and they seem to go very fast..  
up to 6 hours cannot really smell anymore.  
If i were to spray it on my wrist and wait for dry and add Dipropylene glycol would the duration be longer? but yes, i know that the diffusion will get slower.

so lets say i spray IShine 2x on my wrist, and add 1 drop of dipropylene glycol,  
any1 have experience?

Just because you can’t smell the scent package in your [pheromones](https://pheromonelabs.com/shop/) doesn’t mean they’re not working anymore. Not sure how the addition of DPG would do in this case.

From my experience cttm2 works pretty well up to 8 hours ( and even little more).Smell fades but the effect is still present. 😉
