What is Black Reserve kratom extract?

Black Reserve kratom extract is a concentrated extract of Mitragyna speciosa. At 16% total alkaloids, it is Herb Stomp's strongest kratom extract — the most concentrated kratom product we stock, a full tier above our Gold Reserve and many times the alkaloid density of standard leaf powder. It is produced by reducing dried kratom leaf into a concentrated form, so a small amount of extract carries the alkaloids of a much larger amount of leaf.

How kratom extract differs from powder

Standard kratom is sold as milled whole-leaf powder. An extract concentrates that leaf's alkaloids, which is why extracts are measured in grams and sold in much smaller sizes than powder. Black Reserve carries a stated 16% total alkaloid concentration.

Herb Stomp kratom extract tiers

We carry kratom in three concentration tiers, from everyday leaf powder up to our strongest extract:

• Standard kratom powder — milled whole leaf, our everyday strains.
• Gold Reserve — our mid-tier extract (8.69% mitragynine).
• Black Reserve — our strongest extract (16% total alkaloids).
