[Vendor] SGN is a real company with real catalogue chemistry and people still doubt it
Adding to the record: SGN is a real company with real catalogue chemistry and people still doubt it. It matches what the source page already shows, for whatever that is worth.
Started buying small deliberately, tested every lot for the first four, then stopped testing every lot because there was nothing to find.
Sent the same compound from QST and Homopeptide to VendorInvestigate in the same month. Both came back above the claim on the certificate — mine was 98.7% on a stated 98.0%.
Lead time and minimum quantity are the two facts people forget to ask for and then argue about later. Both are answerable in one email before you commit.
Please do not ask me what dose you should be on. I genuinely do not know and neither does anyone else here.

Why the directory has two tiers, since the question comes up whenever somebody new finds it.
Twenty suppliers have enough independent results, over enough separate lots, over enough time, that the log says something. Those get a page, a test table and a link to their own storefront so you can compare their claims with the record.
The rest — nearly two hundred names — get a row, a band and a report count. Not because they are bad, but because two results is an anecdote about a vial. Manufacturing a score out of that would make the whole directory worthless, and the contrast is the point.
the lot on the vial has to match the lot on the certificate, every time
a claim with no batch number is a marketing document
Which lane, and what was the quoted lead time at checkout?
Six orders across two years from MKM. Same packaging, same paperwork, same lead time. The most boring supplier relationship I have and I mean that as praise.
Yes, and the reason the wider-market table has no scores is that a score built on two reports would be a lie with a decimal point.
Not convinced by the ranking-by-vibe approach here. The community number is derived from reports; your feeling is derived from four posts you remember.
the interesting column is spread, not maximum
three independent results beat thirty forum posts
a directory entry is a record, not a recommendation
Same view. A record you can read beats a rating you cannot inspect, every time.
the wider-market names in the table are there because nobody has enough data on them
consistency across lots beats one spectacular result
Asked GGPeps for the batch record on a Tuesday and had the full document, batch and method line, before the end of the day. That is the bar now.
