Oh man that sounds good! I've not had a chance to try Chem 4, but it's "supposed" to be one of the original 13 beans, and the two I've gotten to try (Chemdog, Chem D) are both wonderful in my opinion
I imagine that would essentially be the same lovely stone I've come to expect from the Chem line
As for sleeping with a Chemdog I've managed to get Chem D to put me down for the night, but I also leave them outside until the amber is showing nicely, and then smoke a LOT of it LOL.
Ohhhhhhhhhh! That's pretty bro! This is like watching a Popeye's commercial LOL.
