HERB RESEARCH FOUNDATION

HRF has been studying mitragyna since 1997, and worked closely with Robert Montgomery of Botanical Preservation Corp and Of The Jungle, who was the first to bring mitragyna to the US market in 1995. HRF has been a pioneer in the industry not only in the extent to which it conducts laboratory testing on every lot of botanicals prior to sale, but also to the degree it conducts due diligence with the individuals and companies to whom it sells botanicals, in order to ensure the baseline quality of its botanicals is not altered or compromised on its way to the consumer.

Oregon Residents! Due to a new law concerning the heavy metal allowance in mitragyna products, we regret to inform you that we are not allowed to sell plain leaf or products containing plain leaf. We are currently seeking mitragyna products that comply with these regulations, but it is not a simple or rapid process. Please consider our signature extracts as an alternative, as they do not contain heavy metals in quantities exceeding the limits mandated by this new law.

This is a must buy, I’ve been using kratom for a couple years now and have seen numerous stores selling 90%+ alkaloid kratom extracts…

I didn’t try the MD-90, but he has Red Kali -90 too and that is what I tried. The quality was excellent and I’d definitely recommend it…
