Janoshik COA Reports

Browse the public Janoshik COA scans referenced from the public gallery we reviewed, then use the batch-specific section below for reports published for Calibra Research materials. Every image opens at full size for closer inspection.

Important distinction: the archive below is a public reference collection from the source page, not proof that the pictured batches belong to Calibra Research or that the results apply to any material purchased from us. Only a report tied to the exact batch you hold can support a batch-level claim.

Two different documents, two different jobs

The in-house certificate and the independent report are not rivals. One governs release, the other governs trust. Knowing which one you are looking at prevents most disputes.

Who runs the test

In-house: The manufacturer's own quality-control team.

Independent: A separate laboratory that has no stake in whether the batch ships.

What it proves

In-house: That the batch passed the manufacturer's internal release checks before dispatch.

Independent: That a sample drawn from the stated batch was measured by someone outside the supply chain.

Typical use

In-house: Release-to-warehouse control, lot traceability.

Independent: Independent confirmation when a buyer cannot take the supplier's word alone.

How to read it

In-house: Check it matches the batch you received, then file it with your purchase record.

Independent: Check batch and date first, then verify the report ID against the issuing laboratory where a lookup exists.

How to read a third-party report

Every legitimate independent report carries roughly the same eight pieces of information. If any of them is missing, treat the document as incomplete rather than convincing.

Sample identification

The name the laboratory recorded for the material it received. It should match the product label; if it does not, the report is describing a different vial.

Batch / lot number

Ties the report to one specific production run. This is the single most important line — a certificate only ever describes the batch printed on it.

Date of analysis

When the laboratory actually ran the sample. Together with the batch number it tells you whether the report covers the material you are holding.

Analytical method

Usually HPLC for purity and MS for identity. Two numbers produced by different methods or different labs are not directly comparable — compare like with like.

Purity result

Typically reported as an area percentage from the chromatogram. Read it together with the method line; an area% is not the same thing as a weight% assay.

Quantity / net peptide content

How much material the laboratory quantified. Stated separately from purity, because lyophilised material can carry residual moisture and counter-ions.

Appearance

A simple physical description (colour, form). It is a quick sanity check that the vial matches what the document claims.

Report ID / verification reference

The laboratory's own tracking number. Where the lab publishes a lookup, you can enter it and confirm the report is genuine rather than edited artwork.

No Calibra batch report published yet.

The public archive above is for reference. For a Calibra batch, send us the batch number and we will provide whatever documentation exists for that exact run.

Getting the report for the batch you hold

1
Read the batch or lot number printed on the vial label or the outer carton.
2
Send us that number — and, if you have it, the product name and quantity.
3
We reply with whatever documentation exists for that exact run. If a batch has not been to an independent laboratory, we will say so rather than send you a generic sheet.
4
File it with the vial so the paper trail travels with the material.

Scope note. All materials are supplied for laboratory and scientific research use only. A certificate of analysis is an analytical record for the batch that was submitted — it is not a specification guarantee across production, nor a statement of suitability for any particular application. Purchasers are responsible for confirming that their intended use complies with applicable laws and institutional policies.
