GHK-Cu + BPC-157 + KPV + TB-500 Blend · 50/10/10/10mg

Compound Profile

Two compounds. One vial. Full traceability.

Each blend vial ships with structural data and lot identifiers for both peptides, plus a single Certificate of Analysis documenting per-component purity and the blended composition.

Pre-mixed for the bench.

All four peptides are synthesized via solid-phase peptide chemistry, purified independently by reverse-phase HPLC, and combined in a single vial at a verified 50/10/10/10mg ratio. Mass spectrometry confirms identity for each component, and sterility plus endotoxin testing applies to the final blend.

In the Literature

Two compounds, two research records.

A short, sourced summary of where each compound appears in the published research record. For context only. Not a claim, not a protocol, not advice.

BPC-157 is a 15-amino-acid sequence isolated from a partial fragment of a protein found in human gastric juice. In academic literature it is referred to as Body Protection Compound 157. Most cited research originates from the Sikiric group at the University of Zagreb. Documented preclinical investigation spans soft-tissue signaling, gastric mucosal integrity, vascular pathways, and the nitric oxide system.

TB-500 is a synthetic peptide based on the active region of thymosin β4 (Tβ4), a naturally occurring 43-amino-acid protein first isolated from the thymus gland. Tβ4 is one of the most-studied actin-sequestering proteins in the human body. Documented preclinical investigation spans tissue regeneration, cardiac repair models, ocular surface healing, and inflammatory regulation.

Both compounds are most-cited alongside investigations of angiogenesis, actin cytoskeletal remodeling, and tissue regeneration pathways in animal models. Neither has been approved by the FDA for any therapeutic indication. Both remain classified as research compounds.

For research use only. Statements above describe published research literature and do not constitute health, medical, or therapeutic claims for either compound or for the blend. Not for human or veterinary use. Not evaluated by the FDA.

Common Questions

Answered straight.

Both compounds are tested independently by reverse-phase HPLC and certified at ≥99% per-component purity before blending. The Certificate of Analysis lists the exact lot purity for each peptide separately (most lots run between 99.2% and 99.8%). Mass spectrometry confirms identity for both, and final-blend sterility plus endotoxin testing applies to the combined vial. Your COA ships with the vial and is also retrievable by lot number through our online verifier.

Testing is done by BioRegen Analytical, an independent third-party lab. Every batch of each peptide goes through HPLC purity, LC-MS identity confirmation, sterility screening, and LAL endotoxin testing. The signed Certificate of Analysis ships with each vial. Same lot number, same COA, every time.
