Section 1

Reproducibility across independent tests

Every report below is an observation of the same physical material. What they disagree about is measurement; what they agree about is the lot. The size of the disagreement is compared against what the contributing laboratories' own repeatability figures predict.

Independent assays 13

Median purity 99.50% n=13

Spread (max − min) 1.14pp n=13

Standard deviation 0.344pp n=13

Figure 1. This lot's independent purity results against the whole BPC-157 record set in the index. The vertical line is the index acceptance specification for the tissue-repair and immunomodulatory peptides class, 98.0 % area. A narrow box on the top row against a wide box on the bottom row is the ideal reading: it means the disagreement between lots is much larger than the disagreement within this one.

Member reports 13

Every report the index holds on this lot. Each is a page carrying its own chromatogram, mass spectrum, mass balance, provenance and caveats.

Section 3

By laboratory

Where more than one laboratory assayed this lot, the difference between them is a paired observation of their relative bias — the same material, the same time window, different instruments. Those pairs are what the index's bias estimates are built from.

Laboratory	Reports	Purity results (% area)	Median	Gradient	Published bias (pp)	Bias-adjusted
PeptideMeter	3	99.41, 99.91, 99.50	99.50	28min	-0.05	99.55
Janoshik	5	99.28, 99.34, 99.35, 99.35, 99.93	99.35	30min	+0.00	99.35
Medutest	3	99.93, 99.74, 99.93	99.93	25min	+0.08	99.85
VendorInvestigate	1	98.79	98.79	32min	-0.11	98.90
Kestrel	1	99.70	99.70	15min	+0.24	99.46

This lot contributes 10 paired comparisons to the inter-lab analysis.

The supplier's certificate for this lot

One number the supplier wrote, beside the median of the numbers other people measured on the same physical material. That comparison is only available because the index groups by lot.

Section 5

Impurity fingerprint

The named impurities reported across this lot's assays, with how consistently each was seen. A fingerprint is what allows two lot numbers held by different companies to be identified as one bulk.

Named impurity	Reported in	Median % area	Range
des-Gly truncate (−57 Da)	13 / 13	0.03	0.01–0.19
pyroglutamate cyclisation (−17 Da)	9 / 13	0.21	0.04–0.67
acetylated N-terminus (+42 Da)	8 / 13	0.05	0.02–0.32
[D-Val]-diastereomer	8 / 13	0.02	0.01–0.06
BPC-157 arginine-salt artefact	7 / 13	0.03	0.01–0.10
truncated (1-12)	6 / 13	0.11	0.05–0.30
