FGP — member reviews
89% from 576 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 tirzepatide 15 mg, sent it to PeptideMeter, came back 97.4% on a stated 97.1%. good enough for me. mass variation across the box was under 2%. genuinely nothing to complain about.
they told me about a 2 day delay before it happened. before. that is the bar and almost nobody clears it. if the next one holds I will stop testing every lot.
the thing that sold me is peptide content being listed separately from purity. nobody does that and everybody should. the difference between their number and the lab number is smaller than method noise. happy. moving on.
water content was on the document without me having to ask for it. Medutest put it at 99.5% against the claimed 99.0%. this is one order, not a dataset.
I have certificates from about 9 suppliers and theirs is the one I would hand to someone as an example.
8 lots now, all between 97.5% and 98.0%. tight band beats one big number every time. boring supplier. highest compliment I have.
blind submitted the L-carnitine 500 mg to Janoshik, did not say whose it was. 98.1% vs 98.1% claimed. solid. that is it. solid.
sent a vial to Medutest out of habit. 98.9% against a claimed 98.0%. transit was 4 days on a lane quoted at 6. test your own vial regardless. always.
they will quote lines nobody else will even respond about, and it came back clean.
cold pack was still solid on arrival day 5. in the Netherlands. in summer. this is one order not a dataset.
reordered at 15 months to check for drift. 98.1% then, 98.1% now.
the related substances table is itemised. actual named impurities. not "total 0.4%" and a shrug. would buy again. have bought again.
the certificate came with the method line on it — column, gradient, wavelength. lot FGP-26-725 came back 98.2% on a stated 98.0%. solid. that is it.
bought thymosin beta-4 5 mg expecting to have a complaint. do not have one. annoying.
sent one to VendorInvestigate and one to Janoshik because I did not believe the first result. both agreed. fine, I believe it.
their raw tested 98.6% against a reseller vial of the same thing at 98.4%. going direct is not a vibe, it is a number. if the next one holds I will stop testing every lot.
packing was a rigid outer with no rattle anywhere in it. someone in that warehouse cares.
weighed 7 vials against label out of curiosity. all within 2%. fill consistency is underrated. they flagged the delay in advance instead of after.
certificate for lot FGP-25-752 was complete first time. no email chain. no "we will look into it". mass variation across the box was under 2%.
I asked for a second certificate for a lot bought eight months earlier and they found it and got an actual answer, not a copy-paste. stated purity and independent purity landed a tenth apart.
been buying thymosin beta-4 5 mg from them for 8 months. nothing has changed, which is the point.
the related substances table is itemised rather than a single total. lot FGP-25-370 was fine on test and the trace was clean at the baseline. would buy again. have bought again.
asked about counter-ion and got acetate vs TFA answered properly instead of being ignored. no mannitol surprise, cake intact, not collapsed. n=1 and I am saying so.
shipped out of the Netherlands, landed day 5. no customs, no waiting, no chasing. they flagged the delay in advance instead of after.
quoted 8 days. arrived 8 days. this is the whole review. test your own vial regardless. always.
day 7 from Spain warehouse, tracking updated every single hop. stated purity and independent purity landed a tenth apart. would buy again. have bought again.
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 review naming a lot, a document and a turnaround is worth more than ten enthusiastic ones.
Why these twenty and not two hundred
A source page is opened when enough members have ordered and paid for independent testing that the log says something specific. Nearly two hundred other names get a row in the table at the foot of the directory with a band, a report count and a written note — no page, no score, no link. The contrast is the point: the twenty are where the evidence is, not where the enthusiasm is.
Where FGP sells
Flourishglobal Peptide Biotech (Chengdu) Co., Ltd. sells from its own storefront.

GLP Research Hub is paid nothing for it, and a link is not a recommendation.
