Yeah 91 chem#12 . Its onycd#12 * 91bx2 which is chem 91* onycd which is chem 91 * tresdawg . 91 bx2 is his newer selection of 91bx . Im pretty sure thats what it is . It might be 91 bx backcrossed to the 91 chem again . 91 chem#12 has got to be dank as hell I have a pack.of that too . You will find something elite in there . Its all about selection though . It should be like the 91 cut but with chem d structure . Very nice stuff . You will find a keeper for sure . One of his best works if you like chem d or the skunk va cut . Potential to be even nicer . All the best
