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.

    Takes my gymming to a whole other level. I am a righteous bulldozer while bench pressing on these

    This is quite a low profile kratom rendition that does rather well. Full on energy burst and every bit as good (if not better) than the famed maeng da. Granted, opms makes excellent kratom so I’m not surprised. I rotate both quite often.

    Good clean kratom and has been my goto (in rotation with maeng da) for eons. Opms is damn good at producing solid kratom. It’s my dumb reach, no thinking involved for years now.

    To all the Maeng Da fans, this is better! By a stretch. I mean you generally cannot go wrong with OPMS but this has to be my favorite.
