Rob, I did ISO a week and a half ago or so. There's not a huge improvement with us meth guys..it's honestly all response. But I do "feel" it. It might be placebo for all I know though lol. Just refilled my 2.2 gallon meth tank after 2 months..I love trunk meth kits! Thanks again for the insight again.
