Reconstituted the BPC-157 5 mg and it went clear on contact — no haze, no floaters, no long swirl. Tells you the lyophilisation was done properly.
QST — Qingdao Saber Technology Pharmaceutical
Qingdao, CN · established 2017. The index holds 10 assay reports across 4 batches and 4 compounds, contributed by 4 laboratories. Every figure below is computed from those records and from nothing else.
Where QST sells
Qingdao Saber Technology Pharmaceutical 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.

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
suppressed
n=1
n<3 — see individual records
Index median spread
0.95pp
n=20
Lots tested 3+ times
1
n=4
Fewer than three QST lots have been assayed three or more times, so a reproducibility figure is not computed. Reproducibility cannot be inferred from the number of reports — it needs repeats on the same lot.
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.

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.
Buyer-sourced median
suppressed
n=2
n<3 — see individual records
Supplier-supplied median
98.38%
n=8
Supplier-supplied share of records
80.0%
n=10
Too few records in one or both provenance classes (buyer-sourced n=2, supplier-supplied n=8) to compute a provenance gap for QST. The index-wide effect is +0.31 pp and applies until measured otherwise.
Block 6
Documentation completeness
The score is not an opinion about paperwork. Each component is the share of QST batches in the index whose certificate carries that field, weighted as set out on the scoring rubric.

Block 7
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.
| Compound | Class | Reports | Median % | Index median % | Δ (pp) | Index spec | Pass % |
|---|---|---|---|---|---|---|---|
| NAD+ | Non-peptide | 6 n=6 | 98.02 | 98.88 | -0.86 | 97.0 | 100 |
| Tirzepatide | Incretin | 2 n=2 | n<3 | 98.44 | — | 97.0 | 100 |

Block 8
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 | 4 | 98.59 | +0.00 | 98.59 |
| PeptideMeter | 2 | n<3 | -0.05 | — |
| Nordanalyt | 3 | 97.56 | +0.02 | 97.54 |
| Kestrel | 1 | n<3 | +0.24 | — |
Bias figures are estimated from paired same-lot comparisons and are published with their confidence intervals on inter-lab agreement.

h.moreau91/100
Solid on the semaglutide 10 mg. Purity where it should be, transit 5 days, paperwork in order.
an.amankwah95/100
Three compounds on one invoice, all three lot-matched to their own certificates, all three inside spec on independent testing.
l.haddad95/100
Arrived on day 2 against a quoted 3. Customs paperwork was right first time, which is why it moved that fast.
k.wojcik95/100
Fourth order from them, all thymosin alpha-1 5 mg. Sent one vial from each to Janoshik and the whole set landed inside half a point of each other. That flatness is exactly what I pay for.
i.lindholm91/100
Good communication throughout, accurate lead time, and the parcel arrived on day 4.
b.mwangi91/100
Everything about the order was routine in the best sense — quoted 3 days, arrived in 3.
t.lindholm95/100
Cold pack was still hard on arrival in Vancouver on day 4. My logger never went above 5°C across the whole run.
w.sorensen91/100
Fair pricing for the documentation standard, and delivery landed on day 5 as quoted.
v.abubakar95/100
One of the few places that will quote sermorelin 5 mg at all, and the synthesis came back clean on an independent check.
t.cardoso95/100
Lot code on the vial matched the lot code on the certificate exactly. Sounds basic; it is the single best predictor of everything else.
c.lindholm95/100
Support answered on a Sunday, correctly, with the batch record attached. That is well beyond what I expected.
si.cabrera95/100
Asked a genuinely technical question about pre-dispatch storage and got a reply with numbers in it, inside 3 hours.
a.antonsen95/100
Submitted the epithalon 10 mg to PeptideMeter blind, without telling them the source. 97.6% against a stated 97.5%. The number holds up when nobody knows whose vial it is.
h.beaulieu95/100
Asked for the chromatogram instead of the summary figure and got the real trace, legible, integration visible. They send it without hesitating.
s.correia95/100
First order, deliberately small, glutathione 600 mg only. Documentation, transit and a VendorInvestigate result at 98.8% all checked out, so the next one will not be small.
j.lindholm95/100
Custom synthesis quote came back with a realistic timeline and they beat it. Purity on delivery matched the signed spec.
k.varga95/100
Dispatched from their warehouse in Canada rather than from the factory, so the MOTS-c 10 mg was with me on day 3.
c.danquah95/100
Costed them per mg against three other suppliers on the same NAD+ 500 mg spec. Competitive on price and clearly ahead on documentation.
f.frisk91/100
Ordered epithalon 10 mg twice. Both vials reconstituted cleanly and both matched their certificates.
a.boateng95/100
The certificate for lot QST-24-869 carried method, wavelength, water content and an itemised related-substances table. Complete on the first pass.
r.kimani91/100
Documentation is complete and the numbers are steady. A dependable choice for routine work.
e.almeida91/100
Shipped from their warehouse in the United States, arrived day 4, documentation complete.
d.radich91/100
Steady supplier. Medutest results have agreed with their stated figures on every lot I have submitted.
ru.villalobos95/100
They report purity by RP-HPLC with the wavelength stated and peptide content separately. Two different numbers, correctly separated.
k.okwuosa95/100
Every certificate I have from them is lot-specific. Not one batch-level document in 8 orders.
