TFS — Thermo Fisher Scientific (China) Co., Ltd.
Shanghai, CN · established 2006. The index holds 188 assay reports across 33 batches and 18 compounds, contributed by 6 laboratories. Every figure below is computed from those records and from nothing else.
Where TFS sells
Thermo Fisher Scientific (China) 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.

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.

| Supplier despatch direct to the laboratory | 1 | 0.5% |
| Laboratory retained-sample archive | 7 | 3.7% |
Every record here carries a chain-of-custody line and that line names the route the vial travelled. Of the 188 TFS records the index holds, 38 reached the contributing laboratory from a domestic warehouse rather than as a cross-border consignment, covering 12 of the 18 compounds TFS is represented by here — CJC-1295 with DAC, Cagrilintide, Tirzepatide, BPC-157, Kisspeptin-10, Retatrutide and 6 further compounds. Those are the TFS 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 TFS. 38 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 TFS's own reviewers: 0 of the 12 on-record reviews state a quoted window and what happened against it. The reviews are reproduced in full in Block 11.

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
0.50pp
n=23
Index median spread
0.67pp
n=28
Lots tested 3+ times
23
n=33
Across the 23 TFS lots in the index with three or more independent assays, the median spread between the highest and lowest purity result on one lot is 0.50 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.

Too few records in one or both provenance classes (buyer-sourced n=180, supplier-supplied n=1) to compute a provenance gap for TFS. The index-wide effect is +0.31 pp and applies until measured otherwise.

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.

Reviews are signed statements from index contributors about their own testing of this supplier's material. They are opinions attached to evidence, and they are not used in any statistic on this page.
95.0/ 100738 ratings across the index network
a.balogun99/100
Multiplicity: four independent services hold records against lot TFS-RT10-5306 and two were retrieved from the issuers rather than from the supplier. Both reconciled to the same lot string.
l.rahimi99/100
Peptide content is reported on a line separate from area percent, so the declared mass and the chromatographic figure are not conflated. On a trifluoroacetate salt the difference is material.
s.nilsen98/100
Certificate carries the column, the gradient and the integration threshold as issued. A submitted figure can therefore be compared against a declared one on stated conditions.
z.kowalski97/100
Documentation outside the lyophilised lines is thinner. The oral-tablet certificate held here carries purity and appearance and no dissolution determination; one was supplied on request and is recorded separately.
re.chukwu99/100
Karl Fischer water and bacterial endotoxin by LAL present as issued on the lyophilised lines, neither requested by the submitter.
ka.roos99/100
Blind submission of BPC-157 10 mg returned 99.1 per cent area against a declared 98.0. The declared figure was the conservative one, consistent with the rest of the set held here.
m.laurent98/100
Dispatch note carried the lot string and it matched the vial and the certificate. Transit Shanghai to the EU, nine days, tracked throughout.
y.ndiaye97/100
Warehouse rotation is not published. The lot dispatched was not the lot carrying the most recent certificate; it was identified on request before payment.
o.novak99/100
Related substances itemised by retention time rather than aggregated, which permits a submitted impurity profile to be compared line by line against the declared one.
l.nwosu99/100
Two lots of the same catalogue line held here, four months apart, mean difference 0.2 per cent area. Within the repeatability of the method as stated on both certificates.
b.abubakar98/100
Custom-sequence quotation took four working days against same-day acknowledgement on catalogue enquiries. Recorded as an operational interval, not an assay finding.

Contributor annotations on TFS records 361
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 TFS material are below, each linked to the record it sits on.
The isotope pattern is consistent with the elemental composition of BPC-157. That is a second, independent check on identity and it agrees with the mass.
Purity usually falls between gram and kilogram scale. A figure of 99.54 % on a commercial lot rather than a laboratory batch is the more informative version of this result.
Baseline on this trace is flat enough that the reporting threshold is doing real work rather than hiding peaks in noise. That is a precondition for believing 99.54 % and it is not always met.
A single result at 99.54 % is one draw. What makes a supplier's process legible is the spread across its lots, and that is on the scorecard rather than here. This record is one good point in a distribution worth reading whole.
Purity usually falls between gram and kilogram scale. A figure of 99.79 % on a commercial lot rather than a laboratory batch is the more informative version of this result.
One result at the top of the distribution should not move anybody's estimate much on its own. Purity distributions are compressed at the top and long-tailed at the bottom, so the informative observations are the low ones.
Four slots — water, counter-ion, residual and peptide — are exhaustive and mutually exclusive. Anything that does not fit one of them is a fifth thing nobody measured, and on this record there is no remainder.
Where the close neighbour is an aggregate rather than a related substance, size exclusion separates them trivially and reverse phase never will.
Every annotation the index holds on TFS 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 TFS itself publishes, open thermofisherpeptides.com → alongside.

Where to buy TFS
Thermo Fisher Scientific (China) Co., Ltd. sells direct from thermofisherpeptides.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.
