Slightly embarrassed to be asking this, but: help me understand COA, I have read the wiki twice. My first certificate had a compound name, a percentage and a logo. I…
Controversial — page 12
Positions 276–300 of 1,000 ranked submissions.
Something I keep coming back to: my ferritin moved and I cannot work out whether FFMI is why. Hydration status and fasting state affect the lean mass estimate.…
genuine question about pharmacy that I am slightly embarrassed to ask. I am not trying to be the "source?" guy. I would just like a source. GP said no in the spring,…
Trying to get a straight answer on this: can we stop arguing about normal until somebody posts a number. Wrote the concentration on the vial after reading it here. Have…
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 standardsthe A1c question that gets asked weekly, answered properly. Not a hot take, just something I have not seen said plainly here. Continuous monitoring shows the shape:…
Proposal, not a decision: the Canada rule is doing its job and people should stop complaining. National regulatory approval establishes that a product may be sold.…
Genuine question, and the title is the question: Apotheke — what am I missing here. Asked in my own language at a local pharmacy and got a clearer answer in five…
how much of what we believe about FFMI actually comes from resistance training threads. Searched first, found three threads that contradict each other, hence the post.…
See this a lot, usually framed as "saving product" or "spacing it out a bit". Genuinely asking the pharmacology people here: does nudging the interval to 8-9 days…
Posting this as a discussion rather than a claim: MHRA — 20 things I got wrong before I got it right. Why the monthly pricing tracker works, and the rule that makes it…
The title is the argument: 12 weeks per step is not too slow, it is just unfashionable. Here is the rest of it. Pulling the figures out of the title: 12 weeks. All of…
the "send it again and we will refund the first" message is always a scam, and I want to be careful to separate what I measured from what I felt. The sequence that…
5 months in and PCOS is still the thing I get wrong. Posting the boring middle of the process, because the internet is full of the start and the end and nothing else.…
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…
metformin alongside — keep it or drop it. I am not trying to be the "source?" guy. I would just like a source. Panicked over a first-day sensor reading and rebuilt my…
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.netswitched from compounded to brand and the titration reset itself. I have gone back and forth on this for months. Concentration on the compounded vial was different from…
With oral meds, tapering usually means smaller pills or fewer per day, a fairly intuitive mechanical process. With a weekly injection, what does the community actually…
Here it is: AHI 34 → 9, the CPAP is in a cupboard. One person, one log, no control group, so read it accordingly. Stalled for 10 weeks and measured my waist out of…
Thinking out loud about this: we are measuring sequence at the wrong time and calling it noise. Research-use-only material is not approved for human use. In this board…
9 weeks on 7.5mg, full numbers, ask me anything boring. Same spreadsheet I have been keeping since the start, nothing retrofitted. To save the first four comments: 9…
peer-to-peer review: what to say and what to bring. Short post, long comment section, probably. New plan year, entirely new criteria, and the denial that had been…
Something I keep coming back to: unpopular opinion: most of what gets said here about province is guesswork. A rejected claim at the pharmacy counter and a denied…
The title is the argument: the wiki thing finally clicked for me and I want to write it down. Here is the rest of it. Edited a wiki page for the first time and nothing…
The title is the argument: Janoshik — 19 things I got wrong before I got it right. Here is the rest of it. If the report gives a mass spectrum as well as UV purity, say…
unpopular opinion: most of what gets said here about orforglipron is guesswork. Making the case below, and I expect to lose some of it in the comments. Oral semaglutide…
