private prescription routes vary by region

The confident tone is doing a lot of work that the evidence is not.
Disagree on that part. 99.2% and 96.2% on the same vial is normal.
comment on [Results] 72 weeks, 15kg, and API source was the hard part in c/compounding · 20 points · 1 year ago
This is correct.
Adding to this: compounding is doing more work than the comment implies.
comment on [Discussion] can we stop arguing about telehealth until somebody posts a number in c/compounding · 49 points · 1 year ago
Strongly agree. API source transparency matters.
comment on my TSH moved and I cannot work out whether API source is why in c/compounding · 25 points · 1 year ago
API transparency is the question that separates good compounders from sketchy ones

Yeah, the incretin mechanism is doing the work here.
comment on [Discussion] the receptor advice in here is 4 years out of date in c/glp1science · 0 points · 1 year ago
Respectfully this is a sample of one presented as a finding.
comment on what would you tell week-1 you about regret in c/darkspot · 25 points · 1 year ago
still evidence-based: what went wrong, when, proof

cite the paper: journal, year, first author, links optional

Strongly agree.
Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.
comment on [Vendor] WXT order #17 — the Netherlands, 9 days, no drama, receipts inside in c/glp1uk · 414 points · 2 years ago
Every time this gets posted it hits the front page and every time someone has to re-explain it.
comment on Germany: mechanism, and what it actually costs here in c/glp1science · 21 points · 2 years ago
I am going to push back on this slightly.

Asked 24 compounders about API source. One told me, one dodged, one said they cannot say. The answer is the signal.

The 503A pharmacy I used lost their shortage list eligibility. Same day, compounding became illegal. Rules are real.

The telehealth + compounding combo cost API source plus 23% markup. Not cheap but covered by insurance depending on state.
comment on reading telehealth threads from 2024 and half of it aged badly in c/compounding · 7 points · 2 years ago
Are we talking 503A or 503B?

You have restated the marketing copy. What is the actual substance here.

Strongly agree. API source transparency matters.
