Read-only archive. GLP Research Hub is a static community record — nothing here is for sale, no account is needed, and no vote you cast is counted. Why?

Wiki index

Reference pages plus a wiki for every major community. Written by volunteers, revised when the world changes.

Reference pages

Four hand-written pages that do actual work. These are the ones we link when the same question arrives for the fortieth time.

  • Reconstitution math — mg/mL, syringe units, dead space — with a calculator that shows its working.
  • Reading a COA — Area% vs mass%, identity vs quantity, and the four fields a real certificate has.
  • Storage and stability — What actually degrades, how fast, and why the powder is tougher than the packaging suggests.
  • The first twelve weeks — What the trial titration schedules actually were, and what week 1 to 12 usually feels like.

Community wikis

21 of the 38 communities have their own wiki: what the community is for, every rule with the reason behind it, its vocabulary, and the threads worth reading before you post.

  • c/semaglutide — Ozempic, Wegovy, compounded and research semaglutide. Dosing, titration, results.
  • c/tirzepatide — Dual GIP/GLP-1 agonism. Mounjaro, Zepbound, compounded and research tirzepatide.
  • c/vendorvetting — Independent testing, order records and receipts. Claims need evidence.
  • c/coa — Certificates of analysis, decoded. Post the whole document, not the headline number.
  • c/sideeffects — GI, fatigue, hair, heart rate. What passes, what needs a doctor.
  • c/reconstitution — Bac water, concentration math, syringe units. Show your working.
  • c/retatrutide — Triple agonist. Phase 3 data, research-grade material, and a lot of unknowns.
  • c/hplc — Chromatograms, methods, integration. Bring the raw trace.
  • c/scamalerts — Confirmed fraud patterns, cloned shops, fake COAs. Evidence-only.
  • c/labresults — Third-party test results on real orders. Vendor, batch, service, number.
  • c/compounding — 503A/503B, shortage rules, telehealth pharmacies and what changed this quarter.
  • c/coldchain — Data loggers, excursions, packaging failures. Peptides survive more than you think.
  • c/glp1science — Receptor pharmacology, mechanism, and the papers behind the headlines.
  • c/trialwatch — STEP, SURMOUNT, SURPASS, SELECT, FLOW, TRIUMPH — read the appendix.
  • c/bloodwork — Baseline panels, ApoB, A1c, liver enzymes. Track it, do not guess.
  • c/intlshipping — Lanes, carriers, transit variance. No tracking numbers.
  • c/insurancefights — Prior auth, denials, appeals, formulary exclusions. Templates inside.
  • c/maintenancephase — After the loss stops. Lowest effective dose, regain, and the long game.
  • c/glp1uk — NHS pathways, private prescriptions, pharmacy pricing, MHRA notices.
  • c/newbiequestions — No question too basic. Read the wiki first, then ask anyway.
  • c/meta — The site talking about itself. Rules, moderation, ranking, wiki.

How the wiki works

Anyone with a bit of history on the site can propose a wiki change in c/meta. Changes need a concrete wording suggestion, not a complaint. Pages carry a revision date because advice in this space genuinely does go stale — the compounding section was rewritten twice in one year, and threads from 2024 that once had the right answer now have the wrong one.

What the wiki is not

It is not medical guidance, it is not a protocol, and it is not a substitute for reading the thread. It is a summary of what a lot of people have converged on, which is a useful thing and a fallible one.

Wiki pages are community-maintained summaries, not clinical guidance. If a wiki page and your clinician disagree, your clinician wins.

Site rules
  1. Independent community. Nobody here sells anything, and anyone who tries is banned.
  2. Not medical advice. Describe what you did; never prescribe to a stranger.
  3. Claims need evidence. Batch numbers, dated screenshots, independent test reports, or a citation.
  4. No referral links, discount codes or affiliate URLs. Permanent ban, no appeal.
  5. No contact handles, wallet addresses or tracking numbers — they identify people.
  6. 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.
