Been a user of Mitragyna for almost a decade and I find OASIS to be a reliable and safe provider for the leaf powders which I use. As a Disabled Veteran of 3 wars and a retired pharmacist, I found mitragyna while searching for an ethnobotanical to ease the chronic pain and restless leg syndrome which I suffer from following an injury in the 2003 Iraq War (OIF/OEF). After viewing the ridiculous Government/Big Pharma debacle which continues today to rid the world of this beneficial therapeutic tree, I welcomed the AKA and the standards applied in the "Nutriceutical industry". Oasis meets those standards and has been providing me with safe leaf powders of known terroir and composition which a free from adulteration. Persons using ethnobotanicals must remain vigilant to adulteration as it is prevalent in this industry and could lead to harm if undetected. It is for this reason that I was growing my own Mitragyna speciosa trees in my yard here in south Florida. Since few persons are so motivated and most do not live in such a climate, purchasing plant materials is a best option for most. The standards, the vacuum sealing and the safety analysis for biochemical content, when combined with the screening for microbial contamination, lead me to OASIS and I remain a loyal customer. While other companies provide similar screening and packaging, for a retiree on a fixed income, there is a value factor to consider. OASIS provides great "Bang for the Buck". The ability to buy bulk and mix kg amounts by strain is a feature that saves my money in the long run. I just pop the vacuum sealed packages in the deep freezer and pull one out when I need it. OASIS will succeed as an industry leader due to sound business practices while upholding best AKA standards for their consumers.
