OPMS Silver Maeng Da – Understanding the Ins and Outs

OPMS, or Optimized Plant Mediated Solutions, remains one of the longest-running Kratom manufacturers in the United States. OPMS began producing Kratom Products in 2005. OPMS sells exclusively through physical stores. They use distributors to bring the Kratom to market. Many Redditors describe OPMS as a premium head shop brand. OPMS produces three Kratom lines,

  • Silver
  • Gold
  • Liquid

The Gold and Liquid lines contain only extracts. The Silver line contains extracts, powders, and what OPMS deems alternative products.



OPMS offers several products under its Silver line. They come from different types of Kratom trees. Silver is OPMS’ brand name, not an actual Kratom vein. Because they result from different trees, each Silver product may produce different effects. You should research them before buying to determine the one best suited to your needs.

  • OPMS claims that they strive to sell the highest alkaloid content Kratom possible. They test every Silver batch for purity, ensuring the absence of salmonella, heavy metals, and other contaminants. They also test for alkaloid content. Each batch receives a batch number.
  • OPMS blends batches of their Silver products. They claim blending ensures consistent alkaloid levels.OPMS Silver 1x Extract Maeng Da claims to be an extract, even though OPMS admits that its Silver extracts are not actual extracts. The Maeng Da tree resulted from a graft of other Kratom trees in an attempt to increase alkaloid yield.


  • OPMS Silver 1x Extract Malay contains the “1x” designation, which would indicate that it contains the same level of alkaloids as a regular Malay Kratom. It should also produce the same effects.
  • OPMS Powder Maeng Da comes from the green vein leaves of the Maeng Da tree. Some users report nootropic effects and energy boosts. OPMS markets the product as organic but does not state which standard it uses to meet the organic designation.
  • OPMS Powder Thai comes from the green vein leaves of the Thai Kratom tree. Some users note that this is an energizing and mood-enhancing product. Some reviews also claimed that it increases attention spans and contains other nootropic properties.
  • OPMS Powder Malay Special Reserve comes from the green vein leaves of Malaysian Kratom trees. OPMS fails to explain the “Special Reserve” portion of the title. Users report that it provides a defense against anxiety, helps promote sleep, and effectively kills pain.
  • OPMS Silver Mitragyna Javanica contains no Kratom. It contains Mitrajavine rather than Mitragynine. Mitragyna Javanica enjoys legal status worldwide. Many consider it much milder than Kratom.
  • OPMS Sumatran Cats Claw results from a vine grown in Asia. It supposedly contains anti-convulsive and other neurological benefits, however, no independent testing confirms these effects. It contains no Kratom.
  • OPMS Mitragyna Hirsuta contains the alkaloid Mitraphylline rather than the Kratom alkaloid Mitragyna. Users find their effects less potent than Kratom. It contains no Kratom, but some say it contains analogous but less potent effects.
