Our quality, on the record.
Every certificate we publish is the testing laboratory’s own report, matched to the batch number on the label. This page sets out how our products are tested, where they are processed and shipped, the manufacturing practices behind them, and the research and data that support it, with a source for every claim.
Figures from our lab data study, data as of November 11, 2026
Independent labs, their own reports.
We send batch samples to independent analytical laboratories and publish each certificate as the laboratory issued it, with its own report number.2 The tests on a certificate vary by batch and laboratory, so the certificate itself is the record.
What a certificate in our library can report. Each batch’s published report shows the tests actually completed for it.1,2
| Laboratory | Reports | What the reports cover |
|---|---|---|
| ILS Laboratories | 170 | San Diego analytical lab with a quality system based on ISO/IEC 170253,4. Identity, HPLC purity, net content and a fentanyl screen; full panels add endotoxins, sterility and heavy metals. |
| Chromate | 158 | Identity and quantity, most with HPLC purity. Some reports add sterility, endotoxins and metals. |
| Freedom Diagnostics | 50 | Identity and net content. Most reports print no purity figure. |
| Gold Standard Analytics | 2 | Identity and HPLC purity. |
Report counts from our lab data study.1 ILS also states that peptide testing is not within any accreditation scope and is provided for research use only.3
Where it happens, stated precisely.
Production has separate stages: raw-material synthesis, processing and filling, freeze-drying, testing and fulfillment. They can happen in different places, so we describe each one on its own.5
- Freeze-dryingThe majority of our lyophilized peptide catalog is lyophilized in the United States, with product-specific exceptions.5
- Raw materialsRaw materials may be synthesized outside the United States. U.S. lyophilization describes the freeze-drying step, not where a raw material was made.5
- Other formatsCapsules, liquids, sprays and creams follow their own production pathways and are not part of the lyophilization statement.
- TestingIndependent third-party laboratories, listed above, with each certificate published in the COA library.2
- FulfillmentOrders ship from the US West Coast.
- One product or batchFor the origin details of a specific product or batch, email support@disguisedalpha.com with the product name and batch number.
Why freeze-drying matters
Peptides and proteins are generally less stable in solution, so they are often dried to a solid to reach an acceptable shelf life, and freeze-drying is the most common way to do it. The process itself and long-term storage still need careful control.6
GMP practices, and what they mean.
GMP, Good Manufacturing Practice, is a quality system for how products are made. FDA describes it as systems that assure proper design, monitoring and control of manufacturing processes and facilities.7
Our statement
GMP manufacturing practices are part of how our products are made. That is a statement about manufacturing practices. It is not an FDA approval, and it is not a claim of a particular third-party certification.8
What GMP covers
Written procedures, controlled equipment, trained staff, batch records and the handling of deviations: how the work is done, recorded and checked.7,8 A certificate of analysis is a separate record. It reports measurements on a sample, so we publish both kinds of evidence and keep them distinct.8,2
The research behind the work.
Our own data comes first: every report in the library, counted and published. The outside research below explains why the tests matter.
Our lab data study
We read every certificate in our COA library, 352 batches of 185 compounds tested between November 2025 and November 2026, and published the results, including every result under 98% and the full data as a CSV.1
Stability studies with ILS Laboratories
Two stability studies are being designed with ILS Laboratories: whether larger fill sizes of a lyophilized peptide hold up differently over time, before and after reconstitution, and whether amber glass protects a solution better than clear glass.
Results will be published when testing is complete.10
Why purity is measured
Most peptides are made by solid-phase synthesis, which can leave related impurities such as missing or extra amino acids, oxidized forms and leftover counter-ions. Impurities like these can skew early laboratory studies and lead to wrong conclusions.9
Check our work with your own lab.
Our Verify program lets researchers test a lyophilized research peptide from their order at an approved independent lab. Once the documents are confirmed, the eligible test cost is reimbursed in Disguised Alpha store credit.11

Questions, answered.
Where are your products made and shipped from?
Most of our lyophilized peptides are freeze-dried in the United States, with product-specific exceptions, and raw materials may be synthesized elsewhere. Orders ship from the US West Coast. For the origin details of one product or batch, email support@disguisedalpha.com with the product and batch number.
What does GMP mean here?
GMP manufacturing practices are part of how our products are made: written procedures, controlled production and batch records. It is a statement about practices. It is not an FDA approval or a claim of a specific third-party certification.
How do I find the certificate for my vial?
Open the COA library, choose the product and labeled strength, and match the batch number printed on your label to the report. If your batch is not there, email support@disguisedalpha.com with the product and batch number.
Which labs test your products?
ILS Laboratories, Chromate, Freedom Diagnostics and Gold Standard Analytics issued the 380 reports in our library (data as of November 11, 2026). Each certificate names its laboratory and report number.
What is on a certificate of analysis?
It is a laboratory's report on the tests it ran on a sample: what was measured, the method, the result and the date. Every certificate in our library is the lab's own document, with its report number and the batch it covers.
Are these products for human use?
No. Everything we sell is for laboratory research use only and is not for human or veterinary use.
