Where Homopeptide sells

Hunan Aslsen 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.

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 575 Homopeptide 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 Homopeptide median, 99.34 %; the index median is 98.99 %.
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 0.86pp n=74
Index median spread 0.95pp n=20
Lots tested 3+ times 74 n=93

Across the 74 Homopeptide lots in the index with three or more independent assays, the median spread between the highest and lowest purity result on one lot is 0.86 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 +0.29pp n=93
Index median divergence +0.31pp n=20
Divergences in the supplier's favour 83% n=93
Divergences beyond 1 pp 2% n=93
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 98.95% n=71
Supplier-supplied median 99.43% n=467

Figure 2. Homopeptide 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 Homopeptide 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 Homopeptide 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.

Figure 3. Homopeptide purity by compound, for the 14 compounds with at least four Homopeptide 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.

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.

On-the-record reviews 26

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.

99.0/ 100557 ratings across the index network
h.dumitru99/100

Costed them per mg against three other suppliers on the same IGF-1 LR3 1 mg spec. Competitive on price and clearly ahead on documentation.

j.boateng99/100

Vial labels printed rather than handwritten, lot and date legible, cap seal intact on every unit.

h.ogunleye99/100

Arrived on day 3 against a quoted 4. Customs paperwork was right first time, which is why it moved that fast.

ha.frisk96/100

Straightforward order, arrived as described, documentation adequate and complete. Nothing to add, which is the point.

f.duarte99/100

Moved here after two bad lots elsewhere. 3 orders in and the Medutest numbers have been flat every single time.

k.nyberg99/100

Support answered on a Sunday, correctly, with the batch record attached. That is well beyond what I expected.

b.kaufmann99/100

Weighed 9 vials from the LL-37 5 mg order against label. Every one inside 2% of stated mass. Fill consistency is harder than purity and they have it.

l.petrescu99/100

No customs paperwork, no import wait — it came from their stock in Australia and arrived day 5.

ra.vermeulen96/100

Fair pricing for the documentation standard, and delivery landed on day 4 as quoted.

w.perrin99/100

Vials wrapped individually, foam cut to fit, nothing loose in the box. Packing that has clearly been thought about.

l.boateng99/100

First order, deliberately small, epithalon 10 mg only. Documentation, transit and a Janoshik result at 99.4% all checked out, so the next one will not be small.

co.grimaldi99/100

Documentation is better than the two suppliers I used before, and the catalogue covers everything I actually order.

p.yildiz99/100

The ipamorelin 5 mg arrived on day 2 with the cold pack intact and the seal unbroken. Straightforward, exactly as described.

b.halvorsen99/100

Peptide content reported at 97.7% alongside the purity figure, so I could convert straight to a working mass.

s.hovland96/100

Shipped from their warehouse in the United States, arrived day 2, documentation complete.

ca.ramos96/100

Documentation is complete and the numbers are steady. A dependable choice for routine work.

tu.kaufmann99/100

Ordered on a Monday from their warehouse in Germany and it was here by day 4. That is the whole case for regional stock.

s.ndiaye96/100

Reliable on the general catalogue lines. Purity figures cluster tightly and the certificates match the lots.

ka.castellanos99/100

Their raw material tested 99.8% against a reseller vial of nominally the same compound at 99.3%. Going direct is the whole argument.

a.espinoza96/100

Good communication throughout, accurate lead time, and the parcel arrived on day 4.

l.ndiaye99/100

Submitted the ipamorelin 5 mg to Medutest blind, without telling them the source. 98.5% against a stated 98.1%. The number holds up when nobody knows whose vial it is.

e.salgado99/100

Same lot documentation as the factory ships, but out of their warehouse in Australia, so it landed on day 4.

a.salgado96/100

Domestic dispatch from their stock in Canada. Straightforward, day 3, exactly as quoted.

p.roos99/100

Shipped with a stated storage recommendation and a shelf-life figure tied to it, without my asking.

r.solberg99/100

Regional stock makes the difference — dispatched within Australia, day 3, cold pack still hard on arrival.

e.demir96/100

Solid on the glutathione 600 mg. Purity where it should be, transit 3 days, paperwork in order.
