help me understand denial, I have read the wiki twice. I would rather ask a basic question now than get this wrong quietly for two months. Asked for the policy bulletin…
Top — this year — page 27
Positions 651–675 of 1,000 ranked submissions.
Filing this under things worth writing down: split one vial across Medutest and Janoshik — 99.3% and 98.7%. To save the first four comments: 99.3% and 98.7%.…
how do you actually verify resistance training. I am not trying to be the "source?" guy. I would just like a source. What the evidence actually supports, stripped of…
nobody warned me about muscle cramps and I would have liked the warning. Change my mind, genuinely — I have no stake in being right about this. Switching from…
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 standardsproposal — a flair for long term posts — with the counter-argument included, because I find it fairly persuasive. The habits from the losing phase are what carry it…
units are volume, mg are mass, this is the #1 error on this site. It comes up every few weeks and the answer has not changed. Aim the stream down the wall of the vial…
two labs, same vial, 98.1 and 96.4. both right. I am not trying to be the "source?" guy. I would just like a source. Gave the same trace to two people I trust and got…
can we stop arguing about chargeback until somebody posts a number — that is what I am asking, and I have already read the wiki twice. What is and is not the supplier’s…
The title is the whole question — genuine question about shortage list that I am slightly embarrassed to ask — but here is why I am asking. A 503A pharmacy compounds…
the reconstitution advice in here is 3 years out of date, and I am aware this is a minority view on this board. 3 years. Those are measured, not estimated, and not…
Question in the title, detail here: help me understand formulary, I have read the wiki twice. Prior authorisation criteria are republished each plan year. A criterion…
titration is the most under-discussed thing on this board. Making the case below, and I expect to lose some of it in the comments. The escalation schedule in the trials…
Short version of the title, which is already short: 88% is not "basically fine" and i am tired of that reply. Longer version underneath. Figures up front so nobody has…
The title is the argument: three years of MHRA threads, summarised so you do not have to read them. Here is the rest of it. Concentrations can differ between products…
is 98.0% actually fine or am I being sold a rounding error. That is the headline. The document, the batch and the service are below so you can argue with the method…
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 private prescription thing finally clicked for me and I want to write it down. It is the sort of thing everyone half-believes and nobody writes down. A private…
Posting the full arc because every thread I found while it was happening was written by someone in the middle of it, which is the least reassuring possible moment.…
batch — 12 things I got wrong before I got it right. Not a hot take, just something I have not seen said plainly here. Sent a vial in specifically to check a supplier’s…
SURPASS — 14 things I got wrong before I got it right. Making the case below, and I expect to lose some of it in the comments. Quoted a figure here confidently, got…
Quarterly update. 41 lanes, 900-odd data points, no tracking numbers ever. New this quarter: a quoted-versus-actual column, and p90 alongside the median, both of which…
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…
why does nobody talk about sequence. If this has been answered properly somewhere, link me and I will delete. Assumed regulatory status was static and it was not.…
cloudy after reconstitution — discard, right? right. Not a hot take, just something I have not seen said plainly here. Adding more water does not change how much…
Asking properly rather than in a comment on somebody else’s thread: can we stop arguing about private prescription until somebody posts a number. Discharged at goal…
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…
