Product Description


O.P.M.S.® Silver Capsules

  • The best-selling Kratom Brand in the U.S. The oldest and longest consecutively selling capsulated Kratom product in the U.S.
  • O.P.M.S.’ Silver “1 times Extract” is the best crushed leaf Kratom product on the market.
  • O.P.M.S. is the only company that tests every batch for Alkaloid profile content. Alkaloid profile levels are maintained by blending batches to keep product quality consistent. O.P.M.S. has developed its own Alkaloid Standards specifically designed to measure alkaloids as a standard practice. This practice is unique to O.P.M.S.
  • O.P.M.S. has developed a state-of-the-art process of pulverizing to produce a very fine Kratom powder. This process increases the surface area of the Kratom powder, making it much more desirable to customers. This also allows O.P.M.S. to compact more powder into a smaller capsule.
  • O.P.M.S. products are packaged in FDA-registered facilities and under GMP compliance.
  • O.P.M.S. fine screens all Kratom batches to remove any foreign objects and tests for heavy metals, feces, salmonella, and mold content. O.P.M.S. products are then sterilized for further public safety.
  • O.P.M.S. Silver Capsules are now available in multiple blends: Green Vein Maeng Da, Green Vein Thai, Green Vein Malay.

    Robust Thai kratom capsules that work in a hurry. Ordering my kratom supplies from here is super easy and smooth. They ship out fast and I mean fast, there have been times I’ve placed my kratom order to find that it’s already with the shipping carrier about thirty minutes later lol. Good job guys. Opms kratom is perhaps the best kratom I know and for good reason too.

    Thai kratom is a very energetic kratom in my experience. +1 for all those looking to buy one of the fastest kratom strains.

    I took my first dose yesterday and so far so good!! With these ingredients I’m confident that OPMS Thai will do what I anticipate in the end.

    It very helpful for arthritis. I take it 3x a day for 1 month and may arthritis pain is under complete control for the first time. Thai kratom is very strong and thankfully so. I’ve tried weaker kratom from other brands and have spent a fortune trying to find the perfect kratom – and thankfully this is it for me.

    Surprisingly fast shipping. The easiest way I’ve got my favorite kratom delivered to me. Any kratom by opms hits the spot. Thai kratom is no exception.

    Fire Thai kratom. Who doesn’t love opms kratom? Probably the best there is I should know. I don’t start my day without it and I’m better off for it.
