comment on [Pricing] ON vs AB vs BC, same product, same month in c/glp1canada · 6 points · 4 days ago

Have you seen the special authorization criteria for your province?

comment on TB-500 and Thymosin Beta-4 are not the same product and vendors know that in c/researchpeptides · 28 points · 4 days ago

Net peptide content accounts for counterion, water and residual solvent. On some of these compounds the gap between purity and net content is substantial and entirely honest.

comment on the nausea profile at 7.5 was worse than 10 for me and i cannot explain it in c/tirzepatide · 100 points · 13 days ago

Agree. The GIP component is the interesting half and it barely gets discussed outside c/glp1science.

comment on [Question] Poland — has anyone got a straight answer on special authorization in c/glp1canada · 2 points · 23 days ago

Those criteria were revised at renewal, so the version quoted upthread is out of date.

comment on [Question] Poland — has anyone got a straight answer on special authorization in c/glp1canada · 4 points · 23 days ago

Have you asked the pharmacist to check?

comment on my resting HR went from 58 to 66 on titration and settled back in c/tirzepatide · 9 points · 23 days ago

the appetite effect is blunter than sema, in a good way, most weeks

comment on my resting HR went from 58 to 66 on titration and settled back in c/tirzepatide · 3 points · 24 days ago

Small fix: SURMOUNT is the obesity programme, SURPASS is the type-2 programme. They are different endpoints and the numbers do not transfer.

comment on [Question] Poland — has anyone got a straight answer on special authorization in c/glp1canada · 7 points · 24 days ago

the same product can be covered in one province and not the next

permalink

comment on [Question] does the vial concentration change how much dead space costs me in c/tirzepatide · 5 points · 27 days ago

2.5mg is a four-week starting dose, not a maintenance dose. Worth being precise since people search these threads.

comment on [PSA] PeptideMeter results are area% by default and people keep forgetting in c/tirzepatide · 14 points · 2 months ago

It is a dual GIP and GLP-1 receptor agonist, and the GIP arm is the part that has no equivalent in the semaglutide threads. That is why the side-effect profile reads differently rather than just milder.

comment on [Lab] split one vial across Medutest and Janoshik — 99.3% and 98.7% in c/tirzepatide · 0 points · 2 months ago

It is a dual GIP and GLP-1 receptor agonist, and the GIP arm is the part that has no equivalent in the semaglutide threads. That is why the side-effect profile reads differently rather than just milder.

permalink

comment on [Discussion] can we stop arguing about regain until somebody posts a number in c/tapering · 3 points · 2 months ago

regain is the expected outcome and framing it as failure helps nobody

permalink

comment on [PSA] SURPASS is not what most of this community thinks it is in c/tirzepatide · 1 points · 3 months ago

Disagree with the conversion table. There is no validated equivalence between the two molecules and posting one as though there is does real damage.

permalink

comment on [Question] certificate of analysis — what am I missing here in c/coa · 187 points · 3 months ago

Right, and net peptide content is where the counterion and the water go. Both numbers can be honest and very different.

permalink

comment on why does nobody talk about thymosin in c/researchpeptides · 83 points · 3 months ago

Disagree — that name refers to at least two different molecules depending on who is selling it. The thread needs to be specific.

permalink

comment on [Results] 45 weeks, 14kg, and tirzepatide was the hard part in c/tirzepatide · 10 points · 3 months ago

sulphur burps are the signature complaint and they are not dangerous

permalink

comment on [Results] 45 weeks, 14kg, and tirzepatide was the hard part in c/tirzepatide · 28 points · 3 months ago

Went 10 to 12.5 on the calendar and had the worst fortnight of the whole run. Dropped back to 10 and everything settled.

permalink

comment on reading batch threads from 2024 and half of it aged badly in c/coa · -9 points · 4 months ago

Area percent is the peak area of your compound over the total integrated area, at one wavelength, on one gradient. It is a relative measure of what the detector saw, not a mass fraction of the vial.

permalink

comment on someone explain appetite return to me like I have not read a paper in years in c/tapering · 4 points · 5 months ago

nobody here can write you a taper schedule

permalink

comment on [Lab] 10th independent test on ERP — 97.2% on a claimed 97.0%, and the trend is the interesting part in c/coa · 69 points · 6 months ago

a total of 0.4% tells you less than four named impurities adding to 0.6%

permalink

comment on how much of what we believe about GIP actually comes from SURMOUNT threads in c/tirzepatide · 83 points · 6 months ago

Same experience with the appetite effect being flatter across the week rather than front-loaded.

permalink

comment on COA — 5 things I got wrong before I got it right in c/coa · 23 points · 6 months ago

Area percent or net peptide content? They answer different questions.

permalink

comment on help me understand interval stretching, I have read the wiki twice in c/tapering · 4 points · 7 months ago

coming back later is allowed and it is common

permalink

comment on [Meta] the Zepbound rule is doing its job and people should stop complaining in c/tirzepatide · 401 points · 7 months ago

the appetite effect is blunter than sema, in a good way, most weeks

permalink

comment on [Question] how do you actually verify identity in c/researchpeptides · 72 points · 7 months ago

What storage conditions did they specify?

permalink

comment on unpopular opinion: most of what gets said here about Canada is guesswork in c/glp1canada · 21 points · 8 months ago

the exception drug status route exists in several provinces

permalink

comment on genuine question about COA that I am slightly embarrassed to ask in c/coa · 170 points · 8 months ago

Small fix — 214nm, not 280nm. It matters here because the impurity you are asking about barely absorbs at the longer wavelength.

permalink

comment on switched from 5mg to 15mg and constipation got better, not worse in c/tirzepatide · 19 points · 8 months ago

pens and vials are the same molecule, the price is the difference

permalink

comment on does discontinuation actually matter or is it forum lore at this point in c/tapering · 13 points · 8 months ago

interval stretching is the most commonly described approach here

permalink

comment on three years of 15mg threads, summarised so you do not have to read them in c/tirzepatide · 22 points · 8 months ago

zepbound and mounjaro are the same compound with different labels

permalink

comment on Ireland: Canada, and what it actually costs here in c/glp1canada · 45 points · 8 months ago

Nothing here is medical or legal advice. The pharmacist and the prescriber are the people who can act, and both are faster than a forum.

permalink

comment on [Question] is 99.3% actually fine or am I being sold a rounding error in c/tirzepatide · 20 points · 9 months ago

The thing nobody warned me about was how much of this is logistics — storing it, remembering it, the same day every week.

permalink

comment on [Question] is 99.3% actually fine or am I being sold a rounding error in c/tirzepatide · 178 points · 9 months ago

SURMOUNT-1 ran 72 weeks with the top arm around 21% mean body weight change.

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

permalink

comment on why does nobody talk about interval stretching in c/tapering · 71 points · 9 months ago

Push back: that is a taper schedule aimed at another member and this board does not host those.

permalink

comment on [Discussion] can we stop arguing about water content until somebody posts a number in c/coa · -32 points · 10 months ago

a total of 0.4% tells you less than four named impurities adding to 0.6%

permalink

comment on [Results] 74 weeks, 23kg, and GIP was the hard part in c/tirzepatide · 153 points · 10 months ago

Agree. The GIP component is the interesting half and it barely gets discussed outside c/glp1science.

permalink

comment on special authorization is the most under-discussed thing on this board in c/glp1canada · 19 points · 11 months ago

Kept every form and reference number. When they had no record of a submission, I did.

permalink

comment on the GIP question that gets asked weekly, answered properly in c/tirzepatide · 1 points · 11 months ago

dual agonist, so the GIP arm is doing something the sema threads will not tell you about

permalink

comment on [PSA] tapering is not what most of this community thinks it is in c/tapering · 16 points · 11 months ago

Right, and the habits from the losing phase are the part that has to outlive the dose.
