Our proposed tiers group the measurements that answer a defined question. Identity, HPLC area purity, content, weight, and endotoxin each have a separate meaning. We confirm the method and final quote for each accepted sample.
Peptides and bacteriostatic water only · No scheduled or controlled substances
These are proposed U.S. dollar starting prices, not a checkout or an accepted order. Final price, sample amount, method suitability, reporting units, and turnaround are confirmed before shipping instructions are issued.
Starting prices are per accepted single-peptide sample. A blend or unusual sample may need a different method and quote.
See whether the evidence fits the named peptide and what share of the detected HPLC peaks is the main peak.
Content, sample weight, and endotoxin are separate measurements.
Request this scopeAdd how much of the named peptide is present and how much sample material is there overall.
HPLC area percentage is not a measure of peptide content.
Request this scopeAdd a bacterial endotoxin result when the sample works with the LAL method.
Endotoxin suitability and a reportable range must be established for the sample.
Request this scopeAll tiers include a LabTestedUSA-branded COA format after real testing and review. No sample may be sent until its scope and shipping instructions are confirmed.
Complexity and matrix effects can change the analytical plan. These starting points help plan a request; they are not automatic acceptance criteria.
A blend contains more than one peptide. We plan which components can be separated and measured; one HPLC area-% number may not describe the whole blend.
Additional components and difficult separations are quoted individually.For BAC water, we can review an endotoxin (LAL) request. We first confirm method suitability and agree on EU reporting units.
This scope does not test sterility, preservative concentration, pH, or injection safety.We will only report an assay that is in the agreed sample scope and supported by a suitable method. Raw traces, units, sample identifiers, and limitations belong with the result.
See the reporting approach| Choice | Question it answers | What you receive |
|---|---|---|
| Identity confirmation | Do the measured mass and separation time fit the expected peptide? | LC-MS spectrum and retention context; not proof of the full chain |
| HPLC area purity | Of the peaks this method detects, what share is the main peak? | Area % and chromatogram; not milligrams of peptide |
| Peptide content | How much of the named peptide is present? | Amount with a unit and measurement basis |
| Sample weight | How much sample material is present overall? | Balance weight with a unit and basis, when suitable |
| LAL endotoxin | Is bacterial endotoxin detectable, and at what level? | EU with an agreed unit and range; not a sterility result |
| Peptide Combo | Need identity, HPLC purity, and endotoxin on one peptide? | All three selected analyses, with 10% off their list price |
When issued COAs become available, every released COA is intended to be searchable on the public website by report ID. A client may choose to display only a client ID on that public COA. Personal contact, order, and payment details stay outside the public report.
The privacy choice must be made before report release. It does not hide the released COA itself.

Understand the quote, report evidence, and shipping sequence before preparing a request.
A final quote depends on the peptide, blend complexity, sample form, available material, analytical method, and requested reporting basis. The lab confirms these before it accepts a sample.
The relevant visual evidence and method notes are part of the proposed COA scope when an assay is performed. The exact raw-data package is agreed before testing.
Sample intake is opening soon. Prepare an inquiry first. Do not ship a sample until eligibility, the requested assays, the quote, and shipping instructions have been confirmed.
We will review the peptide or BAC water sample and define an appropriate scope and quote before intake.
