Two-stage release mechanism — preclinical pharmacokinetic context.

Step 01 · 0–4s

Administer (research model)ed

One daily unit enters the upper digestive tract intact.

Step 02 · stomach

Acid-protected

Stability matrix shields the active complex from gastric degradation.

Step 03 · two-stage

Release phase 1

Initial research quantity released in stomach environment for upper-tract activity.

Step 04 · deeper

Release phase 2

Remaining payload continues to small intestine for systemic delivery.

What is Stack 157™?

An oral research formulation combining Pentadeca Arginate, Ac-SDKP and PEA in a two-stage delivery system. Studied for connective-tissue, GI and musculoskeletal pathways in preclinical models.

How is it supplied?

Supplied as oral capsules for research use. Store at 2–8°C, away from light and moisture. Not for human consumption.

What do preclinical timelines show?

Preclinical models show activity at 2–4 weeks. Sustained outcomes build between 6–12 weeks.

Quality controls

Manufactured in a GMP-certified facility, third-party tested for purity and contaminants. Not for human consumption. For research use only.

Are the compounds available separately?

Yes. BPC-157 Arginate (Stack 157), BPC-157 (Core 157), and Ac-SDKP (Gut 157) are available as separate research compounds.
