Good communication throughout, accurate lead time, and the parcel arrived on day 5.
BCH — Bachem Holding (Suzhou) Co., Ltd.
Suzhou, CN · established 2003. The index holds 316 assay reports across 51 batches and 25 compounds, contributed by 6 laboratories. Every figure below is computed from those records and from nothing else.
Where BCH sells
Bachem Holding (Suzhou) 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.

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
1.06pp
n=37
Index median spread
0.95pp
n=20
Lots tested 3+ times
37
n=51
Across the 37 BCH lots in the index with three or more independent assays, the median spread between the highest and lowest purity result on one lot is 1.06 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.

The score is not an opinion about paperwork. Each component is the share of BCH 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.

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.

Block 9
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 | 158 | 98.25 | +0.00 | 98.25 |
| PeptideMeter | 45 | 98.16 | -0.05 | 98.21 |
| Medutest | 45 | 98.29 | +0.08 | 98.21 |
| VendorInvestigate | 27 | 97.77 | -0.11 | 97.88 |
| Nordanalyt | 24 | 98.08 | +0.02 | 98.06 |
| Kestrel | 17 | 98.82 | +0.24 | 98.58 |
Bias figures are estimated from paired same-lot comparisons and are published with their confidence intervals on inter-lab agreement.

94.0/ 100824 ratings across the index network
c.adeyemi95/100
Lot code on the vial matched the lot code on the certificate exactly. Sounds basic; it is the single best predictor of everything else.
z.chowdhury95/100
One of the few places that will quote LL-37 5 mg at all, and the synthesis came back clean on an independent check.
ju.iyer95/100
Custom synthesis quote came back with a realistic timeline and they beat it. Purity on delivery matched the signed spec.
a.vasquez91/100
Ordered CJC-1295 2 mg twice. Both vials reconstituted cleanly and both matched their certificates.
c.batista95/100
Pleased to find they hold stock in the Netherlands. Domestic dispatch, day 3, no customs step at all.
se.silva91/100
Reliable on the general catalogue lines. Purity figures cluster tightly and the certificates match the lots.
a.restrepo95/100
Arrived on day 2 against a quoted 3. Customs paperwork was right first time, which is why it moved that fast.
h.solberg95/100
Regional stock makes the difference — dispatched within Germany, day 4, cold pack still hard on arrival.
p.chukwu95/100
First order, deliberately small, tirzepatide 10 mg only. Documentation, transit and a VendorInvestigate result at 98.5% all checked out, so the next one will not be small.
s.broberg95/100
Quoted 3 days, arrived in 3. Tracking updated at every hop from dispatch to door.
m.cabrera95/100
Submitted the KPV 10 mg to VendorInvestigate blind, without telling them the source. 97.8% against a stated 97.4%. The number holds up when nobody knows whose vial it is.
i.danquah95/100
Documentation is better than the two suppliers I used before, and the catalogue covers everything I actually order.
m.chukwu95/100
No customs paperwork, no import wait — it came from their stock in Germany and arrived day 2.
m.asante95/100
Asked for the chromatogram instead of the summary figure and got the real trace, legible, integration visible. They send it without hesitating.
t.stanescu91/100
Sensible packing, sensible timelines, and a certificate that says what it should. No notes.
s.lindholm91/100
Consistent rather than flashy. Everything lands in the high nineties, and it lands there every time.
d.rahimi91/100
Domestic dispatch from their stock in Canada. Straightforward, day 3, exactly as quoted.
b.coelho95/100
Asked a genuinely technical question about pre-dispatch storage and got a reply with numbers in it, inside 8 hours.
r.rasmussen95/100
9 lots logged now, purity 99.4 to 99.9%. A band that tight is worth more to me than one spectacular number.
k.bakken95/100
Asked them to hold an order until I confirmed a lot number and they did, without fuss and without a restocking charge.
g.correia95/100
Queried the related-substances total on lot BCH-24-406; they came back with method, column and detection limit. That depth is rare.
e.trevino95/100
Their raw material tested 99.8% against a reseller vial of nominally the same compound at 99.6%. Going direct is the whole argument.
e.wikstrom95/100
The certificate for lot BCH-24-704 carried method, wavelength, water content and an itemised related-substances table. Complete on the first pass.
l.erdogan91/100
Solid on the BPC-157 10 mg. Purity where it should be, transit 4 days, paperwork in order.
g.vasquez91/100
Fair pricing for the documentation standard, and delivery landed on day 3 as quoted.
