comment on genuine question about dose stretching that I am slightly embarrassed to ask in c/maintenancephase · 15 points · 1 year ago

Cosigning on planning it in advance. Deciding what maintenance looks like while still losing is much easier than deciding it in a panic.

comment on [Discussion] the escrow advice in here is 3 years out of date in c/cryptopay · 17 points · 1 year ago

Which network, exactly?

comment on help me understand goal weight, I have read the wiki twice in c/maintenancephase · 9 points · 1 year ago

None of this is a taper plan. What dose holds for you is a question for somebody with your history in front of them.

comment on small win: goal weight stopped being a problem at week 85 in c/maintenancephase · 806 points · 1 year ago

maintenance is where the logistics finally get boring, which is the point

comment on [Question] France — has anyone got a straight answer on network in c/cryptopay · 31 points · 1 year ago

Keep every transaction hash in a note file with the order reference. It has resolved two queries instantly.

comment on non-peptide: the version I wish someone had shown me in week 1 in c/orforglipron · 11 points · 1 year ago

Cosigning on daily dosing. It changes the exposure profile and it changes adherence, in both directions.

comment on switched from 1.7mg to 2.4mg and nausea got better, not worse in c/maintenancephase · 1 points · 1 year ago

Has appetite changed, or only the scale?

comment on [Lab] WXT cagri — PeptideMeter came back 97.8% against a claimed 97.0% in c/hplc · 186 points · 1 year ago

UV response is not uniform across species. At 214nm you are looking at the peptide bond, which is why it is the working wavelength for this class; at 280nm you only see tryptophan, tyrosine and phenylalanine.

comment on [Question] is 98.1% actually fine or am I being sold a rounding error in c/hplc · 10 points · 1 year ago

Started reporting my own integrations with the baseline choice stated. Arguments in my threads dropped by about half.

comment on [Discussion] the lowest effective dose advice in here is 2 years out of date in c/maintenancephase · -26 points · 1 year ago

a few kilos of drift is not a relapse

permalink

comment on unpopular opinion: most of what gets said here about confirmations are guesswork in c/cryptopay · 56 points · 1 year ago

screenshot the transaction hash, not the wallet balance

permalink

comment on [Question] chromatogram — what am I missing here in c/hplc · 40 points · 1 year ago

How old is the column and roughly how many injections has it seen?

permalink

comment on rodent data — 9 things I got wrong before I got it right in c/bpc157 · 43 points · 1 year ago

Was there identity confirmation, or only a purity figure?

permalink

comment on [Lab] split one vial across PeptideMeter and VendorInvestigate — 96.8% and 99.1% in c/hplc · -20 points · 1 year ago

Right. And a blank between injections settles the carryover argument before it starts.

permalink

comment on why does nobody talk about gradient in c/hplc · 301 points · 1 year ago

System suitability — repeat injections, tailing factor, plate count, RSD on area — is what tells you the instrument was fit for the measurement that day. Without it, the purity figure is unanchored.

comment on [Meta] the chromatogram rule is doing its job and people should stop complaining in c/hplc · 25 points · 1 year ago

A shoulder that does not baseline-resolve cannot be quantified honestly. You can report it as an unresolved shoulder, which is useful information, or you can develop the method until it resolves.

comment on the crypto thing finally clicked for me and I want to write it down in c/cryptopay · 1 points · 1 year ago

network and address, checked twice, before anything else

keep the hash, it is the only receipt that exists

comment on three years of oral GLP-1 threads, summarised so you do not have to read them in c/orforglipron · 238 points · 1 year ago

Nothing containing this compound is approved by any regulator, and research-use-only material is not approved for human use.

permalink

comment on someone explain LC-MS to me like I have not read a paper in years in c/hplc · 1 points · 1 year ago

Do you have the mass, or only the UV trace?

permalink

comment on how much of what we believe about HPLC actually comes from method development threads in c/hplc · 7 points · 1 year ago

a shoulder is not an impurity until you can resolve it

comment on [Discussion] the regulatory advice in here is 2 years out of date in c/bpc157 · 6 points · 1 year ago

That claim traces back to a single preclinical paper that says something considerably narrower.

permalink

comment on [Discussion] the regulatory advice in here is 2 years out of date in c/bpc157 · 7 points · 1 year ago

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

permalink

comment on reading chromatogram threads from 2024 and half of it aged badly in c/hplc · 1 points · 1 year ago

Same view — reporting the gradient is what makes a result checkable rather than merely stated.

permalink

comment on nobody warned me about early fullness and I would have liked the warning in c/maintenancephase · -37 points · 2 years ago

Interval stretching changes the exposure profile: with a week-long half-life, moving to ten or twelve days lowers trough concentration more than it lowers average exposure. That is why appetite return is often the first thing noticed.

permalink

comment on method development is the most under-discussed thing on this board in c/hplc · 707 points · 2 years ago

you cannot report to two decimals off that baseline

permalink

comment on [Discussion] the crypto advice in here is 2 years out of date in c/cryptopay · 276 points · 2 years ago

Do you have the transaction hash?

permalink

comment on [Discussion] goal weight is doing more work than we give it credit for in c/maintenancephase · 103 points · 2 years ago

the trials that looked at withdrawal are unambiguous about what follows

permalink

comment on [Discussion] can we stop arguing about HPLC until somebody posts a number in c/hplc · 1 points · 2 years ago

LC-MS for identity, UV for relative quantity
