Terramystic Arvostelua 

Best in the business. I’ll keep it short and simple. I have tried at least a dozen different vendors and terra has a good selection and the best quality at the best price.

I too found this vendor on Reddit, and was hopeful, but hesitant. Like you, the masses hadn't steered me wrong in the past, but the prices were significantly lower than others and no working website, it could have been lower quality products or just someone trying to corner a little bit of the white-label market.
Terra Mystic Extracts is a bit better. After dealing with them for 5 months, we're talking over a dozen orders, I can tell you anything and everything you'd like to know about 7OH, mitragynine and it's alkaloids. I know just as much about the market, the TRUTH about the exact nature of the compound, 7 Hydroxymytragynine, as well as parent or founding alkaloid mytragynine. I've experienced quite literally every single product they offer through mid February. They are are excellent.
Ive had very little issues with them, although I will say I believe they grew up, or more like BLEW UP, from a tiny vendor with a dozen or so orders per day, giving out free samples to get the word out and get the products in front of real people that are most likely daily, regular consumers. The chose the perfect place to find the target crowd or audience. The 7OH focused Reddit pages. I came looking for information and stayed because of the insight, the information available. It's not all FACTS, and you have to use some discretion in how much credit you give to whatever you reading, but Reddit is mostly helpful.
They went from a 0 to 100 plus orders a day in less than 5 months, with no website up and running. All word of mouth advertising.
THAT alone should speak volumes. Reddit is a monster, if the quality wasn't there, everyone would know. FAST.
Labs! You never mentioned that all of TMEs products are lab tested and verified certified safe. There was a problem recently with a vendor falsifying labs results, they changed them to make them passing. Those labs tell whether there is any harmful amounts of solvent left behind from the process used to isolate, make 7OH. Good vendors have them available for everything, every single product.Every batch, should have labs available. Terra Mystic Extracts uses the same powders they sell in their tabs. Also, labs let you know your getting the milligrams you paid for. Go to TestMyKratom to learn more about testing. Super interesting...
Overall, 5 Stars for SURE. They go absolutely above and beyond where others can't don't or won't. I believe that so long as they can keep up with the labor part of it, and not get overwhelmed, they'll take the number one spot and keep it. Low prices, same day shipping. Variety and selection that lets you know your not dealing with a little guy. Over two dozen different 7OH powders, 31 to 93 percent. Low medium and high milligram tabs, mitragynine tab and powders. Psuedo, MGM. SR. All available as well and priced better too. Terra Mystic Extracts prides themselves in having the best of of bit of everything.

This site was recommended in a Facebook and in a Reddit group. I was hesitant because they do not have a card processor, payment was bitcoin or Cash app and the prices were really low compared to other companies selling similar products. However, the Facebook and Reddit groups hadn’t steered me wrong in the past, so I ordered. I paid through Cash app, followed the instructions and emailed a picture of the payment and the order. Within an hour I had a confirmation email and a FedEx tracking number. It came in two days. I did have an issue, as part of the order was missing. I contacted customer service and they were really helpful. The missing part was sent overnight, which I did not expect. Customer service explained that the website is relatively new and they are still working out some kinks. They felt bad about it and gave me some freebies, but the real reason for the five star review is because the 30 mg blueberry lemon tablets are amazing and the MIT powder works really well. I would advise being very careful not to use too much of the tablets. They are extremely strong, at least for someone like me who only uses this when the pain is really bad and it has been very bad lately. I took a quarter of a tablet and it took about 15 minutes to fully kick in. I was able to get my physical therapy done and go for a walk. I was amazed. I usually order from Real Botanicals and their product is great too, but way more expensive. This company makes a very affordable option that is also effective. I was quite surprised.
