About
Every Batch. Not Some Batches.
Every product listed on this site cleared purity and identity checks before it went live. Documentation, not promises.
- Minimum purity
- >98%
- Scope
- Per batch, not per catalogue
- Method
- HPLC verified every lot
Process
From Incoming Lot to Live Listing
Four checkpoints between a batch arriving and a product going on sale. Each one produces a record.
- Step 01
Batch Received
Each incoming lot is logged against the product listing before it becomes available for sale.
- Step 02
Quality Review
Purity and identity documentation are checked. HPLC purity result, batch reference, test date.
- Step 03
Released or Rejected
A batch either clears all checks and goes live, or it doesn't and never reaches the catalogue.
- Step 04
Optional Independent Certification
Buyers who need third-party confirmation can add independent US lab certification at checkout — $100, applied once per order.

What a Batch Release Record Looks Like
A specimen of the record every batch is released against. Values shown are an example, not a live lot.

Batch Purity Summary
The HPLC purity result for the production lot, with batch reference, test date, and the pass/fail release note. This is what each listing is checked against before it goes live — a number tied to a lot, not a catalogue-wide claim.
Identity Confirmation
Compound name and target mass checked against the expected identity profile before release. A purity figure means little if the peak belongs to the wrong molecule, so identity is confirmed for every batch alongside purity.
Independent Certification
An optional third-party US lab test covering the full order, added at checkout. It sits on top of the standard batch release process for buyers who need documentation from a lab we do not control.
Reading the data
What an HPLC Chromatogram Actually Shows
The single most important document in peptide quality. Here's how to read one.
The target compound. Peak area represents purity — this is the >98% claim backed by data.
Impurities. Every batch has trace amounts — what matters is they stay below the threshold.
Retention time. Confirms compound identity by matching the expected elution profile.
This is what separates tested from untested. No chromatogram = no proof.
Beyond internal testing
Independent US Lab Certification
Available at checkout for $100 per order. This is separate from the standard batch release process.
- Applied once per order, not per vial.
- For buyers who need third-party confirmation beyond internal testing.
- Useful for higher-stakes research runs where extra documentation matters.
