KP — member reviews
98% from 989 member reports. 26 are published in full below; the rating aggregates all of them. Reviews without an order date or a testable claim are not counted.
This community's number, not a fleet-wide one. Independent groups scoring the same vendor land within a few tenths of each other, and where they diverge it is usually because one group weights logistics and another weights purity consistency.
Ordered PT-141 10 mg twice. Both vials reconstituted cleanly and both matched their certificates.
Pleased to find they hold stock in the United Kingdom. Domestic dispatch, day 4, no customs step at all.
Asked a genuinely technical question about pre-dispatch storage and got a reply with numbers in it, inside 8 hours.
No customs paperwork, no import wait — it came from their stock in the Netherlands and arrived day 5.
Certificate claimed 99.0% on lot KP-25-677. VendorInvestigate came back 99.1%. On an independent column that is as close to agreement as this gets.
Domestic dispatch from their stock in Australia. Straightforward, day 3, exactly as quoted.
Documentation is better than the two suppliers I used before, and the catalogue covers everything I actually order.
Peptide content reported at 99.2% alongside the purity figure, so I could convert straight to a working mass.
One of the few places that will quote AOD-9604 5 mg at all, and the synthesis came back clean on an independent check.
Arrived on day 3 against a quoted 4. Customs paperwork was right first time, which is why it moved that fast.
Their warehouse in Australia had the TB-500 5 mg in stock and it shipped the same afternoon. Tracking never left the country.
3 lots logged now, purity 97.7 to 98.1%. A band that tight is worth more to me than one spectacular number.
Weighed 6 vials from the cagrilintide 5 mg order against label. Every one inside 2% of stated mass. Fill consistency is harder than purity and they have it.
Submitted the BPC-157 5 mg to PeptideMeter blind, without telling them the source. 98.2% against a stated 97.9%. The number holds up when nobody knows whose vial it is.
They report purity by RP-HPLC with the wavelength stated and peptide content separately. Two different numbers, correctly separated.
VendorInvestigate has now seen 8 of their lots through me. Not one has come back outside spec.
The certificate for lot KP-25-799 carried method, wavelength, water content and an itemised related-substances table. Complete on the first pass.
Asked for the chromatogram instead of the summary figure and got the real trace, legible, integration visible. They send it without hesitating.
First order, deliberately small, epithalon 10 mg only. Documentation, transit and a PeptideMeter result at 98.7% all checked out, so the next one will not be small.
The hexarelin 5 mg arrived on day 4 with the cold pack intact and the seal unbroken. Straightforward, exactly as described.
Support answered on a Sunday, correctly, with the batch record attached. That is well beyond what I expected.
Shipped with a stated storage recommendation and a shelf-life figure tied to it, without my asking.
Held locally in the United States, so the IGF-1 LR3 1 mg arrived on day 4 without an import step.
Moved here after two bad lots elsewhere. 6 orders in and the PeptideMeter numbers have been flat every single time.
Custom synthesis quote came back with a realistic timeline and they beat it. Purity on delivery matched the signed spec.
Reconstituted the tesamorelin 2 mg and it went clear on contact — no haze, no floaters, no long swirl. Tells you the lyophilisation was done properly.
What a useful review looks like
Order date, what was ordered, what arrived, how long it took, and whether anything was independently tested. That is it. "Great vendor, fast shipping, A+++" is worth nothing and gets removed; a three-star review explaining precisely what went wrong and how it was handled is worth more than ten five-star ones.
Why the negative ones stay up
A directory of nothing but praise is a marketing brochure. Every source page here carries the disappointing results as prominently as the good ones, and the vendors near the top of the ranking are there because their bad entries are few and old, not because there are none.
