comment on help me understand carrier, I have read the wiki twice in c/intlshipping · 95 points · 1 year ago

Not convinced by four data points. That is not a lane yet, it is an anecdote with a route attached.

comment on [Discussion] we are measuring Mounjaro at the wrong time and calling it noise in c/tirzepatide · 1 points · 1 year ago

This.

Saving this one. It is the clearest statement of the stall problem I have read here.

comment on [Lab] QYB orfo — Medutest came back 99.2% against a claimed 99.0% in c/orforglipron · 72 points · 1 year ago

Push back: daily dosing is not automatically better adherence. It is a different failure mode, not a solved problem.

comment on how much of what we believe about Medutest actually comes from PeptideMeter threads in c/vendorvetting · 46 points · 1 year ago

ask for the batch record before you ask for a discount

comment on [PSA] GIP is not what most of this community thinks it is in c/tirzepatide · 62 points · 1 year ago

hold the dose that works, the ladder is not a leaderboard

comment on the NHS question that gets asked weekly, answered properly in c/glp1uk · 27 points · 1 year ago

Scotland, Wales and Northern Ireland have their own arrangements. An answer that begins with "in England" should say so, and most of the confusion here comes from answers that do not.

comment on stalled for 18 weeks at 12.5mg and I refuse to panic this time in c/tirzepatide · 67 points · 1 year ago

Correction to my own post above — I said 2.5mg and I have been on 15mg since the spring. Same argument, wrong number.

comment on why does nobody talk about lane in c/intlshipping · 1 points · 1 year ago

Push back: comparing a July transit with a February one on the same lane is not a comparison.

permalink

comment on do order records actually matter or is it forum lore at this point in c/vendorvetting · 198 points · 1 year ago

Six orders across two years from WXT. Same packaging, same paperwork, same lead time. The most boring supplier relationship I have and I mean that as praise.

permalink

comment on [Discussion] carrier is doing more work than we give it credit for in c/intlshipping · 58 points · 1 year ago

two identical orders a week apart is the cheapest experiment available

permalink

comment on [Discussion] can we stop arguing about VendorInvestigate until somebody posts a number in c/vendorvetting · 77 points · 1 year ago

Where a supplier holds regional stock, ask which lines are actually held there rather than drop-shipped. It changes the lead time and it changes the customs question.

comment on [PSA] shipping is not what most of this community thinks it is in c/intlshipping · 373 points · 1 year ago

the last mile is where most of the variance lives

permalink

comment on [Question] how do you actually verify Medutest in c/vendorvetting · 8 points · 1 year ago

Which lane, and what was the quoted lead time at checkout?

permalink

comment on PeptideMeter — 8 things I got wrong before I got it right in c/vendorvetting · -2 points · 1 year ago

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.

comment on three years of oral GLP-1 threads, summarised so you do not have to read them in c/orforglipron · 44 points · 1 year ago

Milligram-for-milligram comparison with an injectable peptide is not meaningful and I should not have made it.

permalink

comment on three years of oral GLP-1 threads, summarised so you do not have to read them in c/orforglipron · 22 points · 1 year ago

What analytical method was used — this is not the usual peptide assay question?

Disagreeing with this bit: daily dosing is a different adherence problem, not a better one.

permalink

comment on [Question] how do you actually verify Mounjaro in c/tirzepatide · 1 points · 1 year ago

SURMOUNT-1 landed around 21% at 72 weeks on the top arm

permalink

comment on [Discussion] the regulatory advice in here is 2 years out of date in c/bpc157 · 34 points · 1 year ago

Regulatory classification differs between jurisdictions and has changed in several of them recently. Any answer to a status question needs a place and a date attached.

permalink

comment on tried sequence for 4 weeks. here is what happened. in c/bpc157 · 116 points · 1 year ago

Correction: that study was in rodents. Worth stating explicitly since the thread has been reading it as clinical.

permalink

comment on small win: dual agonist stopped being a problem at week 50 in c/tirzepatide · 70 points · 1 year ago

Agreed, and the trial number is a mean of a very wide distribution — the tails are enormous and nobody posts from the middle.

comment on [Discussion] can we stop arguing about Medutest until somebody posts a number in c/vendorvetting · 159 points · 1 year ago

a directory entry is a record, not a recommendation

permalink

comment on [Discussion] the GIP advice in here is 2 years out of date in c/tirzepatide · 80 points · 1 year ago

a lot of people plateau nicely at 10mg and never need 15

permalink

comment on [Results] 70 weeks on 2.4mg, full numbers, ask me anything boring in c/orforglipron · 1 points · 1 year ago

Daily dosing gives a very different exposure profile from a weekly injectable: peaks and troughs within each day rather than a smoothed weekly curve.

permalink

comment on [Meta] the regulatory rule is doing its job and people should stop complaining in c/bpc157 · 36 points · 2 years ago

research-use-only means not approved for human use, and here that covers everything

permalink

comment on [Lab] GGPeps orfo — VendorInvestigate came back 99.3% against a claimed 99.0% in c/orforglipron · -21 points · 2 years ago

Agreed that phase 3 is where the comparison becomes fair. Everything before it is inference.

tier 3 waiting lists are measured in years, not months

comment on [Meta] proposal — a flair for pharmacy posts in c/glp1uk · 391 points · 2 years ago

What did the referral letter actually say?

permalink

comment on BPC-157 — 8 things I got wrong before I got it right in c/bpc157 · 2 points · 2 years ago

Correction: that study was in rodents. Worth stating explicitly since the thread has been reading it as clinical.

permalink

comment on someone explain pentadecapeptide to me like I have not read a paper in years in c/bpc157 · 5 points · 2 years ago

Cosigning that the papers are more modest than the summaries of them. That is true across this whole site and especially here.

permalink

comment on why does nobody talk about reship in c/vendorvetting · 19 points · 2 years ago

a claim with no batch number is a marketing document

permalink

comment on [Lab] split one vial across Medutest and Janoshik — 98.3% and 98.7% in c/tirzepatide · 1.1k points · 2 years ago

Research-use-only material is not approved for human use. Anything in this thread about how a research vial "should" titrate is a discussion about chemistry, not a plan.

permalink

comment on [Lab] split one vial across PeptideMeter and VendorInvestigate — 99.0% and 99.1% in c/vendorvetting · 194 points · 2 years ago

the interesting column is spread, not maximum

permalink

comment on [Discussion] we are measuring testing at the wrong time and calling it noise in c/vendorvetting · 102 points · 2 years ago

Which lane, and what was the quoted lead time at checkout?

permalink

comment on [Meta] the SURMOUNT rule is doing its job and people should stop complaining in c/tirzepatide · 36 points · 2 years ago

Which week did the appetite change actually land for you?

permalink

comment on [Vendor] QST vs QYB on the same compound, same month — both cleared 99.0% in c/tirzepatide · 78 points · 2 years ago

zepbound and mounjaro are the same compound with different labels
