Safety evidence

Serious or important: potential immunogenicity, aggregation, impurity, or product-quality risks.

A dependable route-specific human interaction and side-effect profile is not established; this is not evidence of no risk.

Interaction evidence

These are general, pairwise evidence notes. Green identifies the potential-synergy category, while Lv3/Lv2/Lv1 communicates evidence strength; it does not guarantee benefit or cancel a safety warning.

With BPC-157

Complementary evidenceLv2

An exploratory rat Achilles-tendon study found improved histology versus control for the combination, but no additional benefit over either peptide alone.

With GHK-Cu

Complementary evidenceLv1

The pair is proposed as complementary from separate evidence involving thymosin-beta-4-related cell migration and GHK-Cu-associated matrix accumulation.

With KPV

Complementary evidenceLv1

The pair is proposed as complementary through separate preclinical rationales involving tissue migration, remodeling, and inflammatory signaling.
