QUALITY
The MaxLab Quality Standard
A research compound is only as good as the documentation behind it. The MaxLab Wellness release panel is built around purity verification, identity confirmation, content assay, elemental impurities, bacterial endotoxins, and sterility — applied uniformly to every research peptide lot through an independent third-party laboratory. The standards below are the standards on the page. They are also the standards on the Certificate of Analysis.
THE RELEASE PANEL
Six standards. Held across every research peptide lot.
The full MaxLab Wellness release panel
Chromato-graphic purity by HPLC-UV/VIS
Every MaxLab Wellness research peptide is tested by High-Performance Liquid Chromatography with UV/VIS detection to confirm chromatographic purity. The MaxLab Wellness release specification is 98% purity. Lots that fail to meet this specification are not released into the catalog. The chromatogram is captured on the Certificate of Analysis.
Content assay by HPLC-UV/VIS
In addition to chromatographic purity, every lot is independently assayed by HPLC to verify that the active peptide content matches the label claim. Most research peptide suppliers do not publish assay results. MaxLab Wellness does. Content verification is reported on every Certificate of Analysis.
Identity confirmation
Peptide identity is confirmed through chromatographic profile, retention time, and supporting mass-spectrometric review. Identity verification protects against substitution and confirms that the released peptide matches its declared sequence.
Elemental impurities by ICP-MS
Every MaxLab Wellness research peptide lot is tested for elemental impurities by Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The panel covers the four elemental impurities most relevant to research peptide chemistry — arsenic, cadmium, lead, and mercury — at limits of quantification down to 0.005 ppm. ICP-MS is the analytical method specified under USP <233> for elemental impurities testing.
Bacterial endotoxins by LAL
Every MaxLab Wellness research peptide lot is tested for bacterial endotoxins using the Limulus Amebocyte Lysate (LAL) assay. The MaxLab Wellness release specification is < 5.00 EU/mg, consistent with the USP/FDA pharmacopeial threshold of 5 EU/kg. Endotoxin control is a critical impurity test for any lyophilized peptide intended for downstream research applications.
Sterility by USP
Every MaxLab Wellness research peptide lot is tested for sterility under United States Pharmacopeia chapter <71>, the compendial sterility test. Lots are released only against a Pass — No Growth Detected result. Compendial sterility testing on every lot is not standard practice across the research peptide category. MaxLab Wellness applies it as the floor.
THIRD PARTY VERIFICATION
Independent third-party testing
MaxLab Wellness’s release panel is run by an independent third-party laboratory. Certificates of Analysis are issued lot-by-lot and made available through the MaxLab Wellness COA Hub. Every COA reports the laboratory ID, lot number, analytical method per test, limit of quantification, result, reporting analyst, and reporting date. The COA is the document. The standards on this page are the standards on the document.
OPERATIONAL DISCIPLINE
Operational standards
Lot-level traceability
Every MaxLab Wellness product carries a lot number that links directly to its specific Certificate of Analysis. The lot system allows researchers to trace any vial, softgel batch, or spray batch back to its synthesis or manufacturing record and to the specific test results for that lot.
Formulation chemistry
MaxLab Wellness invested in formulation development before scaling its product catalog. pH ranges, buffering systems, vehicle composition, and reconstitution behavior were evaluated against stability targets and refined in-house. That work informed our spray product vehicles and our softgel delivery system — the foundation of the World’s First Peptide Softgel™ line.
Cold-source manufacturing and stable transit
Lyophilized research peptides are frozen at the point of manufacture and held at −20 °C through fulfillment. In lyophilized form, peptides remain stable through normal ambient transit, and MaxLab Wellness has validated this across thousands of shipments. Upon receipt, lyophilized peptides should be returned to freezer storage until reconstitution. Softgels and spray products are produced with a 2-year shelf life and held in temperature-controlled storage prior to dispatch.
Manufacturing locations
MaxLab Wellness Softgels are manufactured in California. MaxLab Wellness Spray Products are manufactured in Las Vegas, Nevada. MaxLab Wellness Research Peptides are finished — that is, lyophilized and lot-coded — at our Las Vegas facility. Any imported finished goods, where used, are sourced from FDA-registered partner facilities.
Research-use-only labeling
All MaxLab Wellness products are labeled and sold strictly for laboratory research use only. They are not intended for human or animal consumption. MaxLab Wellness does not provide dosing, medical, therapeutic, diagnostic, or use guidance under any circumstances.
Refund eligibility tied to independent verification
All MaxLab Wellness sales are final. The single exception is identity or purity disagreement. If a researcher submits a MaxLab Wellness lot to an independent third-party laboratory and the resulting report returns identity or purity results materially inconsistent with MaxLab Wellness’s published Certificate of Analysis for that lot, MaxLab Wellness will issue a full refund upon review of the third-party report. This standard places verification on equal footing for both the buyer and the company.
COA REFERENCE
How to read a MaxLab Wellness Certificate of Analysis
Every MaxLab Wellness COA reports the following fields. The table below is a quick reference for what each test confirms.
COA REFERENCE | METHOD | WHAT IT CONFIRMS |
|---|---|---|
Chromato-graphic Purity | HPLC-UV/VIS | Peptide is 98% pure with minimal related impurities. |
Assay | HPLC-UV/VIS | Measured peptide content matches the label claim. |
Arsenic (As) | ICP-MS · LOQ 0.01 ppm | Elemental impurity within release specification. |
Cadmium (Cd) | ICP-MS · LOQ 0.01 ppm | Elemental impurity within release specification. |
Lead (Pb) | ICP-MS · LOQ 0.02 ppm | Elemental impurity within release specification. |
Mercury (Hg) | ICP-MS · LOQ 0.005 ppm | Elemental impurity within release specification. |
Bacterial Endotoxins | LAL | Below the USP/FDA threshold of 5 EU/kg. |
Sterility | USP | No microbial growth detected. Pharmacopeial sterility. |
Each COA additionally carries: laboratory ID, lot number, sample weight, reporting analyst, operations approval, and reporting date.
Tested to a higher standard. Pioneering the next generation of peptide delivery. Softgels and Spray Products manufactured in USA. Research Peptides finished in USA. Independent third-party testing on every lot.
