Question in the title, detail here: what would you tell week-1 you about lipids. Reference intervals are typically the central 95% of a reference population.

About c/bloodwork

What to measure before you start, what to re-measure, and how to interpret movement without panicking. ApoB over LDL-C, HOMA-IR as a crude free tool, ALT and the fatty-liver story, eGFR noise during rapid loss, and the deficiencies that a 1,100-calorie appetite will hand you.

c/bloodwork rules
  1. Post reference ranges with your numbers. Units differ by country and lab.
  2. Nobody here can tell you what a result means for you. We can tell you what it usually means.
  3. Redact identifying details from lab PDFs before posting.
  4. Independent community. Nobody here sells anything, and anyone who tries is banned.
  5. Not medical advice. Describe what you did; never prescribe to a stranger.
  6. Claims need evidence. Batch numbers, dated screenshots, independent test reports, or a citation.
  7. No referral links, discount codes or affiliate URLs. Permanent ban, no appeal.
  8. No contact handles, wallet addresses or tracking numbers — they identify people.
  9. Be recognisably decent. Disagree hard, insult nobody.

Before you read on

Several compounds discussed on GLP Research Hub are sold for research use only and are not approved for human use anywhere. Nothing here is medical advice and none of it is written by your clinician. If a post reads like an instruction, treat it as a description of what one stranger did.
