“Started sema last month, food noise gone in a week, first NSV yesterday.” If that sentence reads like a foreign language, this glossary is for you. GLP-1 communities — Reddit, forums, TikTok — have built their own vocabulary, a mix of medical shorthand, code words and running jokes. Here it is, decoded term by term.
The molecules and their nicknames
- GLP-1: the treatment family — analogues of a digestive hormone (glucagon-like peptide-1) that regulates appetite and blood sugar.
- Sema: semaglutide, the molecule in Wegovy® and Ozempic®.
- Tirz: tirzepatide (Mounjaro®), a dual GLP-1/GIP agonist.
- Reta, R3, “ratatouille”: retatrutide, Eli Lilly’s triple agonist still in trials — approved nowhere to date. The nicknames exist to slip past platform moderation; we devoted a whole article to it.
- Lira: liraglutide (Saxenda®), the daily-injection forerunner.
Treatment, day to day
- Titration: the stepwise increase in dose, usually at least 4 weeks per step, to let the body adjust.
- Maintenance dose: the dose you settle on — reaching the maximum dose is not a goal in itself.
- Half-life: the time the body needs to clear half the medication (about a week for semaglutide) — it’s what explains weekly dosing and the catch-up windows; full explainer here.
- Steady state: the plateau reached after 4–5 weeks of regular dosing, when the medication level stabilises.
- Site rotation: changing the injection spot with every dose (stomach, thigh, upper arm) to avoid local reactions — the guide.
Community vocabulary
- Food noise: the constant mental chatter about food — thinking about it when you’re not hungry, planning, resisting. Its rapid disappearance is the effect GLP-1 users talk about most, and the phrase has gone worldwide.
- NSV (non-scale victory): a win that doesn’t show on the scale — fitting into old clothes, climbing stairs without getting out of breath, improving blood-test results.
- SW / CW / GW: starting / current / goal weight — the three-number signature of every progress post.
- Plateau: the phase where weight stalls despite treatment — common, often temporary, and to be distinguished from a true loss of response (a question for your doctor).
- Regain: weight coming back, particularly after stopping treatment — a research topic in its own right.
- Ozempic face: the media phrase for facial hollowing after rapid weight loss — a consequence of fat loss itself, not a specific effect of the molecule.
- Shortage: the supply strains of 2023–2025 that pushed part of the community towards alternative channels.
- Compounded: (mainly US) pharmacy-compounded versions of semaglutide sold during shortages — outside the manufacturer’s quality chain, and a regulatory battleground.
The grey-market vocabulary
These words come up constantly; defining them is not recommending them — none has any place in supervised care:
- Research use only: the grey-market vial label that claims the product is “for research” — with none of the quality control of an approved medicine.
- Stacking: combining several peptides at once, outside any trial — no safety data exists on these combinations.
- Microdosing: taking dose fractions outside the validated schedule — effects at those doses simply haven’t been studied.
- Counting clicks: splitting pen doses by counting the selector’s clicks — a level of precision the manufacturer does not guarantee outside the intended doses.
One last vocabulary item: journal. That’s the Doza app’s stance — log your doses, weight and injection sites, draw your estimated level curve, and never suggest anything beyond that. Your measurements and doses never leave your iPhone, whatever treatment you follow.
FAQ — GLP-1 vocabulary
What does “food noise” mean?
The constant, intrusive thoughts about food. Many GLP-1 users describe its disappearance as the first effect they notice, sometimes within the first few weeks.
What do SW, CW and GW stand for?
Starting weight, current weight, goal weight — the three markers displayed in community progress posts.
Why do people say “reta” or “ratatouille” instead of retatrutide?
Because openly discussing an unapproved medication exposes posts to platform moderation — communities use nicknames to slip through. Our dedicated article tells the whole story.
What is titration?
The stepwise dose increase (generally at least 4 weeks per step) set out in the product information to improve digestive tolerability. The exact schedule comes from a prescription, never from improvisation.
General information: this glossary describes usage and vocabulary; it does not recommend any of these practices. For any treatment decision, your doctor and pharmacist remain the right people to ask.
