comment on [Denied] reason code says "not medically necessary" at BMI 38. sure. in c/insurancefights · 8 points · 4 days ago
The practical rule people converge on is 28 days at fridge temperature after first puncture, and that comes from the preservative, not the peptide.
comment on [Failure] gel pack arrived liquid and warm. photos at unboxing. in c/coldchain · 39 points · 5 days ago
This is the "correlation is mechanism" thing again. You changed three variables at once.
comment on how many independent tests before you trust a vendor. my number is three in c/vendorvetting · 10 points · 9 days ago
Correct. The batch number is load-bearing information, not optional.
comment on [Question] does the copay card stack with anything or is that a myth in c/insurancefights · 9 points · 10 days ago
say which country and which plan type
comment on [Titration] 12 weeks per step is not too slow, it is just unfashionable in c/tirzepatide · 105 points · 15 days ago
The dual agonism story is real. The appetite is physically different from semaglutide alone.
comment on [Paper] amylin co-agonism is genuinely different pharmacology, not just more GLP-1 in c/glp1science · 7 points · 15 days ago
Strongly agree. Central appetite is real but people overstate it.
comment on SURMOUNT-1 was -20.9% at 72 weeks. that is the number, not -30% in c/tirzepatide · 0 points · 16 days ago
the appetite change on tirz is more than just reduced hunger, it is different machinery
comment on [Paper] amylin co-agonism is genuinely different pharmacology, not just more GLP-1 in c/glp1science · 29 points · 16 days ago
comment on anyone else find 15mg genuinely unpleasant with no extra loss in c/tirzepatide · 7 points · 18 days ago
the dual agonism hits different and that is why people describe it differently
comment on [Appeal] peer-to-peer review: what to say and what to bring in c/insurancefights · 150 points · 22 days ago
This is the "correlation is mechanism" thing again. You changed three variables at once.
comment on three years of gastric emptying threads, summarised so you do not have to read them in c/glp1science · 8 points · 1 months ago
amylin is not GLP-1, posts conflating them get corrected
comment on [Vendor] MKM communication is slow but the material has been fine in c/vendorvetting · 37 points · 1 months ago
comment on the prior authorization question that gets asked weekly, answered properly in c/insurancefights · 79 points · 1 months ago
What was the denial code?
comment on am I the only one who found data logger harder than the injections in c/coldchain · -29 points · 1 months ago
data logger is the standard, gut feeling is not
comment on [Question] Ireland — has anyone got a straight answer on gastric emptying in c/glp1science · 129 points · 2 months ago
the half-life is incretin, affects steady state timing
comment on what would you tell week-1 you about testing in c/vendorvetting · 74 points · 2 months ago
You have restated the marketing copy. What is the actual substance here.
comment on genuine question about incretin that I am slightly embarrassed to ask in c/glp1science · 19 points · 2 months ago
The confident tone is doing a lot of work that the evidence is not.
comment on help me understand incretin, I have read the wiki twice in c/glp1science · 250 points · 2 months ago
The practical rule people converge on is 28 days at fridge temperature after first puncture, and that comes from the preservative, not the peptide.
comment on [Discussion] GIP is doing more work than we give it credit for in c/tirzepatide · 123 points · 2 months ago
Switched from sema at 1.0mg to tirz at 1.7mg. Different drugs, cannot compare the doses directly.
comment on reading SURMOUNT threads from 2024 and half of it aged badly in c/tirzepatide · 1 points · 3 months ago
the GIP side does different things than the GLP-1 side, that is the point
