Clinical perspective, offered as context rather than as advice.

For compounded supply users considering compounded for the first time: here's a step-by-step guide:

  1. Get a prescription from your doctor (telehealth counts)
  2. Research 503B compounding pharmacies with good community reviews
  3. Verify their FDA registration and inspection history
  4. Request a COA for your specific compound before ordering
  5. Start with a 1-month supply to test
  6. Consider sending a sample to Janoshik for independent verification
  7. Track your response compared to brand (if you were on it previously)

Compounding pharmacy red flag checklist for compounded supply — if ANY of these apply, find a different source:

  1. No verifiable physical address
  2. No pharmacist available for consultation
  3. COA not available or clearly template/fake
  4. Prices dramatically below market ($30-40/month = suspicious)
  5. No prescription required
  6. Ships without cold pack or temperature control
  7. No batch/lot numbers on product labeling
  8. Pushes "research use only" products for human injection

Your health depends on product quality. Don't cut corners on source verification.

Agreed on the mechanism, with the caveat that the head-to-head used semaglutide 1mg, not 2.4mg. It is still the best direct evidence available, but it is not the comparison most people think they are citing.

This is exactly what I could not find anywhere else.

Moderator note: good thread. Keeping it here rather than moving it, because the question is general enough to be useful. Carry on.
