Well the dilution at present isn't doing anything for me. I am still positive.
Dilution techniques in any configuration are not a 100% sure thing. It must be understood that dilution techniques can backfire if the THCA concentration in the bladder is too high. For most heavy users, it would be virtually impossible to dilute that concentration enough without overdiluting and sending up the red flags at the lab.

If you plan on utilizing the N2 Dilution method, be sure to use Gatorade in place of water. Specific gravity is another constituent checked by the labs (as well as creatinine) in determining an overly-diluted sample. Gatorade helps keep satisfactory SG numbers while water consumption decreases SG.
