Multi-Peptide Blends

Pre-combined multi-peptide research formulations, supplied in single vials as lyophilised powder for laboratory research use only. A blend is a convenience and a complication in equal measure, and the complication is worth understanding before comparing one against a single-compound vial.

What is actually in each blend

Every blend on this site states its per-component mass, because a blend’s total mass tells you nothing about how much of any one compound you have:

• BPC-157 & TB-500 10 mg — BPC-157 5 mg, TB-500 5 mg
• BPC-157 & TB-500 20 mg — BPC-157 10 mg, TB-500 10 mg
• CJC-1295 (no DAC) & Ipamorelin 10 mg — CJC-1295 without DAC 5 mg, Ipamorelin 5 mg
• GLOW 70 mg — BPC-157 10 mg, TB-500 10 mg, GHK-Cu 50 mg
• KLOW 80 mg — BPC-157 10 mg, TB-500 10 mg, GHK-Cu 50 mg, KPV 10 mg

A blend priced against a single-compound vial is a category error unless that split is known. GLOW’s 70 mg looks large next to a 10 mg vial, but 50 of those milligrams are GHK-Cu. See what cost per milligram hides and what is in KLOW and what each component is studied for.

Why a blend is harder to characterise

A single-compound certificate reports one purity figure against one target mass. A blend has to report each component separately, and that raises problems a single vial does not have:

• Co-elution. Components with similar hydrophobicity can overlap on a reverse-phase column, so a chromatogram of a blend is harder to resolve than a chromatogram of either compound alone.
• Ratio verification. Establishing that a vial contains the stated ratio is a quantitative measurement, not the same as establishing that each component is pure.
• Mixed stability. The components do not degrade at the same rate. GHK-Cu carries redox-active copper; BPC-157 does not. The blend’s practical shelf life is set by its least stable component.
• Attribution. If a result looks anomalous, a blend gives you no way to attribute it to one component. For work where that matters, single vials combined at the bench are the better tool.

Analysis and handling

Products are third-party tested for HPLC purity; certificates are published on product pages and on the certificates of analysis page, and vials are matched to their certificate by cap and crimp colour, and identity data is given per component on each listing: sequence, formula, mass, CAS and PubChem link. Store to the requirements of the least stable component — see storage and stability.
