What Are Immune Peptides?
A simple introduction to immune peptides, anti-inflammatory signaling, adaptive immunity, and neuroimmune communication.
Immune Peptides in Plain Language
Immune peptides are research compounds that interact with the immune system — the body's defense network of cells, signals, and organs. Unlike drugs that suppress or broadly stimulate immunity, the compounds in the OSYRIS Immune category modulate specific immune mechanisms: inflammatory signaling, T-cell maturation, and neuroimmune communication.
Anti-inflammatory (KPV) — A tripeptide that blocks NF-κB, the master switch for inflammatory gene activation. Stops excessive inflammation at the source.
Adaptive immunity (Thymosin Alpha 1) — Promotes T-cell maturation and enhances immune cell quality. The only compound in the OSYRIS catalog approved as a medication in 35+ countries.
Neuroimmune (VIP) — A neuropeptide that bridges the nervous and immune systems, with receptors on both neurons and immune cells.
Integrated (KLOW stack) — KPV + BPC-157 + TB500 + GHK-Cu for protocols studying inflammation control alongside tissue repair.

Common Questions
Do immune peptides "boost" the immune system?
Not in the simple "boost" sense. They modulate specific immune mechanisms. Thymosin Alpha 1 enhances immune cell quality. KPV reduces excessive inflammation. VIP bridges neural and immune signaling.
Which has the most clinical evidence?
Thymosin Alpha 1 — approved in 35+ countries with clinical trial data from multiple randomized controlled studies.
What is NF-κB?
The master transcription factor controlling hundreds of inflammatory genes. KPV blocks it from activating.
What is neuroimmunology?
The study of how the nervous and immune systems interact. VIP is a research tool for this field.
Are these FDA approved?
Not in the US. Thymosin Alpha 1 is approved in 35+ other countries. OSYRIS versions are research-grade for laboratory use.
What is the KLOW stack?
KPV + BPC-157 + TB500 + GHK-Cu — combining anti-inflammatory and tissue repair compounds for integrated protocols.
