OPMS Silver Red Sumatra is red vein leaf from the island of Sumatra, Indonesia, packed into clean 0.6g capsules by one of the longest running names in American kratom. OPMS has kept its Silver capsules on shelves for well over a decade, and this red is the one experienced customers pick when they want a classic Sumatra for the evening without measuring powder. Each bag is held to 1.55% mitragynine (about 9.3mg MIT per capsule), so the bag you buy next month matches the one you finish today. Choose from 30, 60, 120 or 240 capsules.
What Sets This Red Sumatra Apart
- A Stated Alkaloid Figure: 1.55% mitragynine on every bag, a little above the 1.1% to 1.5% typical of plain leaf
- Blended Batch to Batch: OPMS tests each batch and blends to hit the same number, bag after bag
- Mature Sumatran Leaf: A traditional red vein from one of Indonesia's best known kratom regions
- Easy Math in Grams: Every capsule holds 0.6g, so counting capsules is counting grams
- A Heritage Line: OPMS calls its Silver capsules the longest consecutively selling capsulated kratom in the U.S.
