Optimized Plant Mediated Solutions (O.P.M.S.) Review  

O.P.M.S. kratom review banner with company logo

Optimized Plant Mediated Solutions – better known as O.P.M.S. – is among the leading kratom brands in the United States. It is also one of the oldest, having cemented its place in the domestic retail space long before the average consumer ever heard of Mitragyna speciosa. But is it as good as its longevity would suggest?

We decided to find out what kind of brand we were dealing with. The following is our comprehensive review. Read on for all the pros and cons of Optimized Plant Mediated Solutions.

What is O.P.M.S. (Optimized Plant Mediated Solutions)?

O.P.M.S. first hit the scene in 2005, becoming one of the first smoke shop kratom brands. By 2009, this wholesale kratom manufacturer had expanded its scope by rolling out its online platform. Soon, online retailers were adding O.P.M.S. products to their collections.

Despite its internet-based success, O.P.M.S. remains one of the brands most synonymous with brick-and-mortar kratom. If you’ve walked into a headshop or convenience store, chances are good that you’ve come across a prominent O.P.M.S. display or two.

There appear to be two related O.P.M.S. websites, although we have yet to confirm that BuyOPMS is owned by the same company. Therefore, if you want to purchase some of its items without being a wholesale client or going through a different vendor, you can do so.

While this debate roars on, one thing is sure: O.P.M.S Kratom wants you to know that it cares about quality. That is why it was one of the first vendors to participate in the AKA’s GMP (Good Manufacturing Practices) Standards Program. This program was developed to protect consumers and holds kratom processors accountable.

As a GMP participant, O.P.M.S. must submit its kratom products to a third-party audit. This ensures purity and potency. While it is unclear how often vendors must be tested, the company’s compliance sends a positive, reassuring message to would-be consumers.

What It Has to Offer

Optimized plant mediated solutions product line display

O.P.M.S. has three main product lines. Several years ago, these lines included only one strain each. Now,  customers have a few more options to choose from. They include O.P.M.S Black, O.P.M.S. Silver Capsules and Powder, O.P.M.S. Gold Capsules , and O.P.M.S. Liquid.

O.P.M.S. has a limited selection of strains, such as Maeng Da, Malay, and Silver Thai. This vendor makes up for its lacks of variety with its rich kratom extracts. Still, if you’re more interested in raw kratom powder, it’s going to be hard to find a better option than Golden Monk’s own collection of plain leaf powders and capsules.

What It Costs and How It Compares

If you buy kratom made by O.P.M.S., you’ll often be at the mercy of a retailer’s chosen price point. The good news is that Optimized Plant Mediated Solutions published its suggested retail price chart online for anyone to see. You can ensure you’re paying only the fair market value by checking it.

Liquid kratom extracts are suggested to start at $17.99 per unit, but BuyOPMS offers each bottle for $16.95. Meanwhile, old-school O.P.M.S. Kratom Powder should start at $7.49 for an ounce of Maeng Da, with an ounce of Malay going for $8.49, and an ounce of O.P.M.S Silver Thai selling for $7.19.

These prices (mostly) compare favorably to those charged by online kratom vendors. For example, Amazing Botanicals charges $5.99 for 30 grams, while Choice Kratom charges $17.99 for the same.

Before adding this brand’s products to your shopping cart, you should check if your preferred payment method is accepted. Different sellers accept different payment methods. Payless Kratom accepts credit cards, while Kures Apothecary accepts Bitcoin and credit cards.

O.P.M.S. Customer Reviews

If you want to see kratom enthusiasts get into a considerable debate, bring up Optimized Plant Mediated Solutions. A thread about O.P.M.S liquid shots got a lot more heated. One Redditor said, “OPMS doesn’t hold a flame to Magnum Opus Extract.” Another stated that “OPMS did nothing for me.”

At the other end of the spectrum, a Reddit member warned users against O.P.M.S. Black, writing, “Be careful…they have changed me for the worse… I am not the same. I’ve f***ed up my body, mind, and wallet BADLY… the worse thing I ever did and regret doing was buying one of these and trying them… I’ve easily blown 10 grand this last year and a shell of my former self.”

Another jaded user said, “I’ve used this brand a couple times and had wildly different results each time, ranging from good for headshop shit to weird and not kratom-like. Today I got the worst shit imaginable, and it’s enraging to think it must be some other substance, and I have no clue what it is.”

MIT45 premium product display

MIT45 is another undisputed leader of the kratom industry, and we’re not just saying this because they’re our parent company. the biggest threat to O.P.M.S.

This trailblazing kratom manufacturer has kept consumers consistently pleased with its ever-expanding repertoire of innovative kratom extracts.

K Tropix

K-Tropix is another line of innovative products with a proprietary twist on the kratom extract. This mitragynine-dominant “kratom-enhanced nootropic” contains a bracing blend of vitamins and herbs, including Bacopa Monnieri, Ginkgo Biloba, Phenibut, and Vinpocetine.

At an average price of $22.39 for a four-pack of capsules, it’s less affordable than MIT45 or OPMS, but it’s equally potent. K-Tropix is widely available from online wholesalers, such as Payless Kratom.
