Where SSA sells

Shanghai Sigma-Audley New Material Technology 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.

Laboratory retained-sample archive115.0%

Every record here carries a chain-of-custody line and that line names the route the vial travelled. Of the 219 SSA records the index holds, 31 reached the contributing laboratory from a domestic warehouse rather than as a cross-border consignment, covering 15 of the 27 compounds SSA is represented by here — IGF-1 DES (1-3), BPC-157, Semaglutide, Semax, Sermorelin, SS-31 (Elamipretide) and 9 further compounds. Those are the SSA 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.

One contributor on the record below documents SSA stock held in Germany, with a transit of 2 working days against a quoted 2. Germany is the only regional stock location named anywhere in SSA's record here, and one consignment described by one buyer is exactly that. It is not a warehouse list and the index has not verified it.

The index measures nothing about lead time — it assays material, it does not buy it. What it has is SSA's own reviewers: 3 of the 26 on-record reviews state a quoted window and what happened against it, and 1 of them describes same-day dispatch. Where SSA despatched a sample direct to a laboratory, the courier leg ran a median 7 days across 37 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.

Figure 1. Purity distribution for all 219 SSA records carrying a purity figure. Domain fixed at 92–100 % area and bin width 0.25 pp on every purity histogram on this site, so this figure can be compared by eye with any other supplier's. Dashed line is the SSA median, 98.24 %; the index median is 99.08 %.
Block 3

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 0.84pp n=27
Index median spread 0.67pp n=28
Lots tested 3+ times 27 n=39

Across the 27 SSA lots in the index with three or more independent assays, the median spread between the highest and lowest purity result on one lot is 0.84 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.

Median COA divergence +0.06pp n=39
Index median divergence +0.06pp n=28
Divergences in the supplier's favour 59% n=39
Divergences beyond 1 pp 0% n=39
Block 5

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.

Figure 2. SSA purity by sample provenance. Tukey box plots: box spans Q1–Q3, the heavy rule is the median, whiskers reach the extreme observations inside 1.5 IQR of the box, and points outside the fences are plotted individually. The vertical line is the SSA overall median. Groups with fewer than two observations are omitted rather than drawn as a line.

Documentation completeness

The score is not an opinion about paperwork. Each component is the share of SSA batches in the index whose certificate carries that field, weighted as set out on the scoring rubric.

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.

Figure 3. SSA purity by compound, for the 14 compounds with at least four SSA records. Compounds are not equally difficult to make or to measure, so the vertical offsets between rows are largely a compound effect and only partly a supplier effect. Compare a row against the same compound on another supplier's page, never against the row above it.

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.

Contributor annotations on SSA records 346

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 SSA material are below, each linked to the record it sits on.

Doubling column length gains 40 % resolution and doubles the run. On a routine release method that trade is usually declined, and the certificate should say which method was run.
A retail vial is also a test of the label. Declared claim 2 mg against what the gravimetry recovers is a question only a purchased vial can answer honestly.
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.
Rounding convention is the least of what a certificate carries. Lot code, method, wavelength and release date are the fields that let a reader reconstruct the figure, and the index scores those separately on the documentation rubric.
Expanded uncertainty on a purity figure is about half a point. A declaration rounded to the nearest half point is quantising at roughly the resolution of the measurement, which is defensible practice rather than sloppy practice.
A reference standard on the same sequence would upgrade this from a good mass to a traceable one. The distinction matters where a result is going to be cited rather than merely read.
Every named impurity on this record has a mass defect consistent with its structural assignment. That is the check that distinguishes an assignment from a guess.
The gap between 97.89 % and the class specification should be read against an expanded uncertainty of roughly ±0.5 pp. A shortfall inside that band is not a finding; a shortfall well outside it is.

Where to buy SSA

Shanghai Sigma-Audley New Material Technology Co., Ltd. sells direct from shanghaisigmaaudley.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.
