I'm not disagreeing about the Cdub. IME, it's a nice dank OG cut very similar to many of the other ones floating around Socal. I don't know Cdub, nor the history of it, so I can't comment on it's authenticity, etc.
In regard to legit labs in CA. I don't know of a single one, let me explain why. I have a close friend that sold Gas and Liquid Chromatographs to pharmaceutical testing facilities for over 20 years. Real Pharma Testing where EVERYTHING has to be tested in Triplicate, with daily calibration of the equipment, and PHD quality technicians running with lab grade test samples and daily equipment maintenance. Not some "home-made" calibration solutions, but legit lab grade facilities and materials access. He was part of the initial move towards Cannabis testing years ago, but considering the volatility of the Cannabis market and the crazy amount of money they already make doing legit Pharma testing, it became a no go. Why risk a multi-million dollar successful lab equipment firm trying to maybe make "extra" money off illegal cannabis testing in the future? Idea didn't get past the first person with a business preservation mentality, understandably. We tested a a bunch of all our strains back then with his testing facilities and I think the highest we were getting back (on all the same strains we have today) was around 18%, if I remember correctly.
