About NSI-189

NSI-189 is an experimental small molecule (not a peptide) studied for depression and to grow new hippocampal neurons, sourced in research for mood and neurogenesis work. It ships as capsules or a powder.

Its reported half-life is ~17–20 hours, which is the main reason the community cadence above looks the way it does. Not FDA-approved.

How to Read the NSI-189 Capsules Comparison

  • Stock status — Live in-stock state for each NSI-189 Capsules listing, refreshed on a recurring basis.

Reading NSI-189 Capsule Listings

Capsule listings are ranked on total NSI-189 per bottle — capsule count multiplied by milligrams per capsule — rather than on bottle price, because a cheaper bottle with fewer or weaker capsules routinely costs more per milligram. A capsule COA should test the finished capsule rather than the raw powder, and it should cover the exact capsule strength on sale.

Oral capsule formats differ from injectable vials in route of administration and bioavailability, so a NSI-189 protocol written for one format does not transfer to the other. Confirm the vendor's COA covers the capsule product specifically.
