JEEP — Guangzhou JEEP Biotechnology Co., Ltd.
Guangzhou, CN. The index holds 230 assay reports across 38 batches and 24 compounds, contributed by 6 laboratories. Every figure below is computed from those records and from nothing else.
Where JEEP sells
Guangzhou JEEP Biotechnology Co., Ltd. sells from its own storefront. The link is marked nofollow and sponsored: it exists so the figures on this scorecard can be read against what the supplier itself publishes. The index is paid nothing for it and a link is not an assessment.
Every figure above describes lots the index has seen. It says nothing about the lot you are offered, and the only check that does is the one on the certificate against the vial.

Identification
Business facts, held constant across the index and not derived from the data. The index sells nothing and takes no supplier payment for placement; the storefront link below is marked nofollow and sponsored so a record can be checked against the seller, and is not a recommendation.

Dispatch and regional stock
Counted from the chain-of-custody line on this supplier's own records, which names the route each vial travelled to the laboratory, and from the on-record reviews below. The index has no sight of any supplier's warehouse network and publishes none.

| Retail purchase via a third-party forwarder | 34 | 14.8% |
| Supplier despatch direct to the laboratory | 5 | 2.2% |
| Laboratory retained-sample archive | 17 | 7.4% |
Every record here carries a chain-of-custody line and that line names the route the vial travelled. Of the 230 JEEP records the index holds, 41 reached the contributing laboratory from a domestic warehouse rather than as a cross-border consignment, covering 16 of the 24 compounds JEEP is represented by here — Retatrutide, Semax, BPC-157, TB-500, N-Acetyl Semax Amide, PT-141 (Bremelanotide) and 10 further compounds. Those are the JEEP lines this index has actually seen arrive from regional stock, and they are a count of consignments rather than a stock listing: a line missing from them may simply never have been submitted for assay.
No contributor to this index has named a regional stock location for JEEP. 41 of its records nevertheless arrived by a domestic-warehouse route, so stock is held somewhere; the index does not know where and will not guess.
The index measures nothing about lead time — it assays material, it does not buy it. What it has is JEEP's own reviewers: 4 of the 26 on-record reviews state a quoted window and what happened against it, and 1 of them describes same-day dispatch. Where JEEP despatched a sample direct to a laboratory, the courier leg ran a median 7 days across 5 such consignments — that is a transit time the index can see, and it is not the same thing as a lead time. The reviews are reproduced in full in Block 11.

Headline statistics
Each figure carries the n it was computed from. The n= badge next to a statistic is the number of records it was computed from. Below n=8 the badge is amber. Below n=3 the statistic is suppressed and the individual values are shown instead.

Reproducibility across independent tests of one lot
Where the same physical lot was assayed more than once, the spread between those results is a property of the material and the fill, not of the market. It is the rarest and most informative statistic on this page, and it exists only for lots someone tested twice.
Median within-batch spread
0.63pp
n=28
Index median spread
0.67pp
n=28
Lots tested 3+ times
28
n=38
Across the 28 JEEP lots in the index with three or more independent assays, the median spread between the highest and lowest purity result on one lot is 0.63 pp. Interpreting that number requires the laboratory repeatability figures: the best contributing laboratory here repeats to 0.16 pp and the worst to 0.34 pp, so a within-lot spread under about 0.5 pp is indistinguishable from measurement noise and a spread above 1 pp is a statement about the material.
Block 4
Supplier certificate against independent measurement
The supplier's own COA purity figure for a lot, minus the median of the index's independent observations of the same physical lot. Positive means the certificate reads higher than the measurement. Rule AX-R05 fires above 1.5 pp.

Provenance — where the tested material came from
Supplier-supplied samples are weaker evidence than independently purchased ones, because the supplier chose the vial. The index measures the size of that effect rather than assuming it.

Coverage by compound
The delta column is this supplier's median minus the index-wide median for the same compound, which is the only comparison worth making: comparing a supplier's aggregate against another supplier's aggregate compares their product mixes as much as their process control.

Quarterly trend
Submission volume is not market share and a quarterly median is not a trend unless the compound mix held still. Both caveats apply to every row below.
Median purity by quarter
Quarters with fewer than two purity records are gaps in the line rather than zeroes.
Coverage growth
Records added per quarter. Growth here is index coverage, not supplier volume.

Which laboratory produced these numbers
Laboratories disagree with each other by a measured amount. A supplier tested mostly by one laboratory carries that laboratory's offset in its aggregate, and the adjusted column removes it.
| Laboratory | Reports | Median purity | Lab bias (pp) | Bias-adjusted |
|---|---|---|---|---|
| Janoshik | 110 | 99.38 | +0.00 | 99.38 |
| PeptideMeter | 43 | 99.33 | -0.05 | 99.38 |
| Medutest | 33 | 99.35 | +0.08 | 99.27 |
| VendorInvestigate | 16 | 99.12 | -0.11 | 99.23 |
| Nordanalyt | 19 | 99.46 | +0.02 | 99.44 |
| Kestrel | 9 | 99.71 | +0.24 | 99.47 |
Bias figures are estimated from paired same-lot comparisons and are published with their confidence intervals on inter-lab agreement.

Contributor annotations on JEEP records 484
Annotations are this index's only discussion surface: signed technical comments attached to a specific record by a named contributor. They are not moderated for agreement with the index's own arithmetic. The most recent on JEEP material are below, each linked to the record it sits on.
On a low-resolution pair the baseline between the peaks never reaches baseline, so any integration is an extrapolation. Stating which extrapolation was used is worth more than any threshold.
Valley height relative to the smaller peak is the practical criterion an operator uses, and it is not on the report. Resolution is a proxy for it and an imperfect one on asymmetric pairs.
Anyone comparing this purity figure against a result from a longer method should expect a difference of a few tenths in a predictable direction. The inter-lab page quantifies it per laboratory.
Reported as signed ppm, which is the right convention: direction carries information about calibration that a modulus discards.
Fair.
Independently purchased, at the submitter's own cost, forwarded without the supplier's involvement. That is the definition and this record meets it.
A unit-resolution instrument confirms that a species of approximately the right mass is present. It never confirms a species of exactly the right mass, and the index's status vocabulary distinguishes the two deliberately.
An unrecognised sodium adduct shifts an apparent monoisotopic mass by about 22 Da, which at this molecular weight is far more than -15.2 ppm. Rule that out first; it is the cheapest check available.
Every annotation the index holds on JEEP material sits on its own record; the full set is reachable from the record listing and from each contributor's page. To read them against what JEEP itself publishes, open jeepbio.com → alongside.

Where to buy JEEP
Guangzhou JEEP Biotechnology Co., Ltd. sells direct from jeepbio.com. Everything on this page describes lots the index has already seen; the certificate that matters is the one that arrives with the vial you order, and the lot code on it should match the vial. Ask for the lot-specific document rather than the batch-level summary, and ask for the integration report if you intend to reconcile the figure yourself.
