Our obsession:
peptides with proven purity.
Every vial that leaves our laboratory is synthesized according to the strictest standards, analyzed by an independent laboratory, and traced back to the batch number. Here's how.
From raw peptide to certified vial.
Each MyPeptide product goes through five controlled steps. None can be bypassed, and each is documented to ensure complete batch traceability.
SPPS Summary
Solid-phase peptide synthesis (SPPS) is performed in a state-of-the-art partner laboratory under a controlled atmosphere. The SPPS method allows for a high-fidelity amino acid chain, the basis for any purity exceeding 98%.
Preparative HPLC Purification
The crude peptide is purified by preparative high-performance liquid chromatography (HPLC). This step separates the target peptide from synthesis by-products and residual impurities.
Freeze-drying and packaging
The purified peptide is lyophilized under vacuum to ensure optimal storage stability. It is packaged in a borosilicate glass vial under an inert atmosphere, with a brombutyl stopper and a sealed aluminum cap.
Janoshik Independent Analysis
A sample from each batch is sent to Janoshik Analytical, independent laboratory. Measures include: HPLC purity, heavy metals, endotoxins, identity by mass spectrometry.
Lot release and COA available upon request
The full report is kept in our archives and is provided to you upon request in PDF format, including batch, date and signature.
Three specialized scientific actors.
We rely on three recognized partners for pharmaceutical synthesis, analysis and logistics.
Synthesis laboratory
SPPS synthesis on a certified site. Monthly capacity: several hundred grams of high-purity peptides.
Janoshik Analytical
International reference in HPLC chromatography for research peptides. Analysis of each batch before being put on the market.
Pharmaceutical logistics
Logistics partner specializing in temperature-controlled shipments and discreet packaging for research.
Three commitments, without exception.
If any of these commitments are not met on your order, we will refund you in full without conditions.
Minimum purity 98%
Any vial whose Janoshik analysis reveals a purity of less than 98% is destroyed before being put on sale.
COA provided upon request
The complete certificate of analysis for each batch is available to you and will be sent to you upon request by our support team.
Batch traceability
Each vial has a unique lot number which allows you to find the COA, the date of synthesis and the analyst.
Standards and compliance.
We apply the strictest pharmaceutical industry standards for research peptides, even when regulations do not require it.
