Every batch that leaves our laboratory goes through a four-stage quality control process. HPLC, mass spectrometry, endotoxin control and full traceability by batch code. Without this, no sale.
Each batch is verified by High-Performance Liquid Chromatography before leaving the lab. ≥99% purity is the minimum threshold, not the goal. If a batch doesn't meet it, it's discarded.
The Certificate of Analysis documents purity, identity, contaminants and endotoxins of every batch. Issued by an external independent laboratory, not ours. No COA, no sale.
Each vial has a unique batch code. Scan the QR, see when it was synthesized, which laboratory verified it and which batch it belongs to. If you have a problem, we know exactly which vial you're working with.
Endotoxins are bacterial toxins that can contaminate poorly manufactured peptides. Our threshold is less than 0.5 endotoxin units per milligram, the pharmaceutical standard. Most vendors don't measure or report it.
Before a peptide enters your kit, it goes through four quality control stages. If it fails at any of them, the entire batch is discarded. There is no "pass with observations".
Solid-phase synthesis (SPPS) in GMP-certified laboratories. Each amino acid is coupled sequentially, controlling temperature, pH, and reaction time. Batches with <99% coupling efficiency are rejected at this stage.
Purification by high-pressure liquid chromatography. Separates the target peptide from byproducts, truncated fragments and residual reagents. Repeated until purity meets ≥99%.
A sample from each batch is sent to an external laboratory. HPLC + LC-MS + LAL test. The COA issued by that laboratory is what travels with the vial. No verification, no labeling.
The peptide is lyophilized (dehydrated by sublimation) in sterile vials under controlled conditions. Vacuum-sealed with butyl cap and aluminum crimp. Batch code label printed on the spot.
From the moment the peptide leaves the lab until it reaches your door, we don't break the cold chain. Controlled storage, refrigerated transport, 24/7 monitoring.
Optimal preservation to maintain peptide stability and purity.
Continuous temperature alarms and logs. Full cold-chain traceability.
Vials protected from light for maximum stability during transport.
Every batch has a unique code + Certificate of Analysis available.

Documentation
Yes. On each product page there's a link to the current batch COA. If you want to review beforehand, email hello@superbiolabs.com and we'll send the document.
External accredited laboratories, not ours. It's independent control. Lab names vary by region but all are ISO 17025 certified.
It's discarded. Entire batch. No negotiation. We re-synthesize from scratch. That's why some products occasionally go briefly out of stock — we prefer stockout over lowering the standard.
Any modern camera app reads it. Takes you directly to the COA for the specific batch of your vial, not the generic product COA.
Three ways: 1) Scan the vial QR and verify it matches the batch code on the label. 2) Inspect the vacuum seal (must be intact). 3) If in doubt, send a photo of the vial and batch to our team and we'll confirm.
Our supplier laboratories have GMP. External labs issuing COAs have ISO 17025. As a RUO (Research Use Only) product, we don't require FDA approval — it's not an approved drug for clinical human use.
Every product in the catalog meets these standards. Every vial comes with its COA. Every batch, validated.
