I have had 17 orders now and I keep a table, so here is the honest summary rather than a vibe. Material has been consistent. Communication has not. Shipping has varied…

comment on 14 months in and formulary is still the thing I get wrong in c/insurancefights · 13 points · 1 year ago
Rodent data is rodent data. Dose scaling is not linear and the models tell you what to investigate, not what to expect.
comment on area percent — my 20-week log, condensed into one table in c/coa · 80 points · 1 year ago
Strongly agree. Mass% and area% are answering different questions on the same document.

the related substances line is where the story is
comment on help me understand appeal, I have read the wiki twice in c/insurancefights · 34 points · 1 year ago
step therapy documentation is the weapon, use it
comment on [Discussion] we are measuring COA at the wrong time and calling it noise in c/coa · -36 points · 2 years ago
Yeah, 96.8% area is not the problem, the missing impurity breakdown is the problem.

Sent one vial to PeptideMeter and VendorInvestigate. 96.8% and 99.1%. Cost me more than the vial did and I would do it again.

Water content was 3.8%, acetate was 6.2%, purity was 99%, but net peptide was only 90% of the label weight. Perfectly honest, just chemistry.

purity and net content are two different numbers, same vial
Disagree on that part. 97.4% and 97.6% on the same vial is normal.
comment on three years of pentadecapeptide threads, summarised so you do not have to read them in c/bpc157 · 2 points · 2 years ago
The injection-site soreness was genuinely awful for three weeks and then simply stopped. I know that is not useful information, but it is what happened.

handlers in the community are rare and cautious
Right, the pentadecapeptide question again, but with numbers this time. I have 7 data points over 12 weeks. The pattern is consistent enough that I do not think it is…
comment on tried purity for 3 weeks. here is what happened. in c/coa · 63 points · 2 years ago
area% is not mass%, and here is exactly why it matters
comment on small win: step therapy stopped being a problem at week 35 in c/insurancefights · 133 points · 2 years ago
Denied for prior auth, resubmitted with denial documentation, approved on appeal. The criteria exist, you just have to meet them.
comment on [Meta] the batch rule is doing its job and people should stop complaining in c/coa · 239 points · 2 years ago
redact your own name, not the vendor's batch details
Adding to this: water content is doing more work than the comment implies.

This is the correct framing. The COA structure matters as much as the number.
comment on anyone else notice nausea kicking in around week 60 in c/sideeffects · 561 points · 2 years ago
This is the "correlation is mechanism" thing again. You changed three variables at once.
comment on what changed for me between week 40 and week 89 in c/coa · 1 points · 2 years ago
Water content on the document? That affects your concentration math.
comment on switched from 0.25mg to 1.7mg and the nausea got better, not worse in c/coa · 451 points · 2 years ago
post the whole document, not the headline number
