GLOW

Description

GLOW (GHK-Cu / BPC-157 / TB-500 Blend) is a popular research peptide combination (often marketed as the “Glow Blend” or “Glow Stack”) sold by various suppliers for laboratory studies. It typically combines GHK-Cu (copper tripeptide for skin/collagen research), BPC-157 (for tissue repair models), and TB-500 (Thymosin Beta-4 fragment for actin regulation and regeneration studies). Common vial compositions include ratios like 50mg GHK-Cu + 10mg BPC-157 + 10mg TB-500 (total 70mg), though exact amounts vary by supplier.

Since this is a blend/mixture of three distinct peptides (not a single compound), it has no unified CAS number, molecular formula, or molecular weight. These properties are defined separately for each component. The blend itself is not assigned a single CAS (listings often show N/A or blank for the mixture).

GHK-Cu (Copper Tripeptide-1 / Prezatide Copper)

• CAS Number: 89030-95-5 (most common for the copper-complexed form in cosmetic/research contexts; some list 49557-75-7 for related GHK-Cu variants)
• Molecular Formula: C₁₄H₂₂CuN₆O₄ (or variations like C₁₄H₂₄CuN₆O₄ / C₂₈H₄₈CuN₁₂O₈ depending on coordination/protonation reporting)
• Molecular Weight: Approximately 401.9 g/mol (commonly 401.91–403.96 g/mol; minor differences from hydration/salt forms)

BPC-157 (Body Protection Compound-157)

• CAS Number: 137525-51-0
• Molecular Formula: C₆₂H₉₈N₁₆O₂₂
• Molecular Weight: 1419.5 g/mol (or 1419.54–1419.56 g/mol)

TB-500 (Thymosin Beta-4 Fragment, often Ac-LKKTETQ or similar active sequence)

• CAS Number: 77591-33-4 (for full Thymosin Beta-4) or 885340-08-9 (for the common synthetic TB-500 fragment); 77591-33-4 is frequently cited in blend contexts
• Molecular Formula: C₂₁₂H₃₅₀N₅₆O₇₈S (for the larger fragment commonly used)
• Molecular Weight: Approximately 4963 g/mol (or 4963.44–4963.55 g/mol)

Notes:

• The “GLOW” name is a marketing term for this synergistic blend in regenerative/skin health research models (e.g., wound healing, collagen support, anti-inflammation). No single chemical entity exists under “GLOW.”

GLOW (GHK-Cu / BPC-157 / TB-500 Blend)
GHK-Cu

Molecular Formula: C₁₄H₂₄CuN₆O₄

GHK-Cu is a copper-chelated tripeptide composed of glycine, histidine, and lysine. Its stable metal–peptide coordination makes it a common reference material in analytical research examining metallopeptide binding behavior, structural stability, and chromatographic characterization.

BPC-157

Molecular Formula: C₆₂H₉₈N₁₆O₂₂

BPC-157 is a synthetic 15–amino-acid peptide arranged in a compact linear sequence of polar and charged residues. It is frequently used in research settings for studies involving peptide stability, degradation profiling, and mass-spectrometric identification of short-chain peptide structures.

TB-500 (Thymosin Beta-4 Fragment)

Molecular Formula: C₂₁₂H₃₅₀N₅₆O₇₈S

TB-500 is a synthetic 43–amino-acid peptide fragment derived from the Thymosin Beta-4 sequence. Its extended chain length and flexible structure make it suitable for analytical studies focused on large-peptide purification, folding behavior, and chromatographic separation of long-form peptide analogs.
