Two years ago I bought a decommissioned system for less than a decent bicycle. Since then I have learned more analytical chemistry than I ever wanted and spent more…

Posting this because it is the worst result in my log and hiding it would be pointless. Field Value Vendor not naming yet — see below Product semaglutide 10mg Service…
Sent USDC on the wrong chain. Vendor's address was correct, the network was not. The funds exist, they are just somewhere neither of us can reach without the vendor…
nausea day 2 post-injection like clockwork, week 14, does it ever stop. Posting the boring middle of the process, because the internet is full of the start and the end…
Sigma-Aldrich — certified reference materials
Reference standards, analytical reagents and system-suitability material. If you are running your own method, start with a known.
Reference standardsFlairing this as a question deliberately, because I have one number in a field where there are almost no numbers and that is not enough to conclude anything about…
That is the entire event. They said eighteen days. It took seventeen. I want to talk about why this feels remarkable, because it should not. Eleven of twelve member…
England. Full timeline, dates approximate to the month for obvious reasons. Month 0 — GP referral to specialist weight management. BMI comfortably over threshold, two…
why 1mL syringes cause overdoses and 0.3mL ones do not. If you already knew this, the post is not for you and you can scroll on. 1mL and 0.3mL. Those are measured, not…
the gradient everyone uses for sema and why it under-resolves the des-amido. It comes up every few weeks and the answer has not changed. The system suitability…
The one-line version is the title: no tracking numbers. they identify both ends. removed on sight. The rest is why. The rigid outer with no rattle in it was the thing…
TRIUMPH timeline — what we actually know vs what gets repeated. Change my mind, genuinely — I have no stake in being right about this. Nothing containing this compound…
Short public-service post: severe abdominal pain is not a forum question. Held the dose for an extra six weeks instead of stepping. The sulphur burps settled and I lost…
The phase 2 MASH results ( NEJM , 2024) are, to me, the most underdiscussed thing in this whole space. Biopsy-confirmed endpoints. Not an ALT screenshot, not imaging,…
Asking properly rather than in a comment on somebody else’s thread: why is nobody talking about the SURPASS-CVOT readout. Vials and pens carry the same molecule; what…
Fourth report in six months alleging SGN is not a real supplier. Every time, the reasoning is some version of "the site looks like a distributor rather than a peptide…
Janoshik Analytical — independent HPLC & mass spec
Send the vial, get the number. Third-party purity and identity testing, results published to you regardless of what they say.
Test a vialSponsoredGL Biochem (Shanghai) Ltd. — the synthesis house
Est. 1998. ISO 9001 and cGMP, 1,500+ staff, 200+ patents. There is a fair chance the vial you are about to send for testing started here. Batch-specific COA as standard.
glbiochem.netThe title is the argument: sterile water is not bacteriostatic water and it is not close. Here is the rest of it. Research-use-only material is not approved for human…
get these before you start, you cannot go back for them later. Making the case below, and I expect to lose some of it in the comments. Added ApoB to the panel after a…
Trying to work out what makes a document a result rather than a general statement about a product line. The one in front of me — FGP cagrilintide — has a compound name,…
Following on from the area% thread, because the same confusion turns up in a second form. People read a 10mg vial at 99% purity and conclude they have 9.9mg of peptide.…
Two weeks ago I posted that a QYB certificate had a producer string inconsistent with laboratory software and implied it was generated. It was a re-export. The original…
503A vs 503B in one paragraph, because everyone conflates them — a position I have arrived at slowly and would like tested. Asked for the beyond-use date basis and got…
Package went missing between Zhuhai and here. Tracking died in a transit hub and stayed dead for eleven days. Sent one email with a screenshot of the dead tracking page…
i stopped eating at 70% full and the vomiting stopped entirely. That is the headline. The document, the batch and the service are below so you can argue with the method…
Six orders from JEEP over about fourteen months. Guangzhou to Manchester every time. Nothing has gone wrong. Not one thing. Which is genuinely making me nervous,…
Short answer, for anyone who finds this from a search: no. Longer version. A COA from an actual laboratory is exported from instrument software or from a LIMS. The PDF…
