Community talk. May be wrong. Not medical advice. Not a protocol. Not for human or animal use.
Systemic weekly GLP-1 shot — whole-body appetite, not a site pin.
EECOH-1 tested these weekly ecnoglutide arms against placebo.
Sponsor tables report distinct week-40 and week-48 weight outcomes; these are trial arms, not a community chart.

Timing context & sources
Half-life in the body
Steady-state ecnoglutide half-life was 124–138 hours in the Phase 1 multiple-dose cohorts.
Healthy participants received 0.2–0.6 mg subcutaneously once weekly for six weeks after single-dose cohorts spanning 0.03–1.0 mg.
Small early-phase healthy-participant pharmacokinetics do not establish long-term outcomes, gray-product identity or a subjective-effect duration.
- Guo et al. — Discovery of ecnoglutide: a novel, long-acting, cAMP-biased GLP-1 analog (opens in a new tab)Phase 1 healthy-participant study: single doses 0.03–1.0 mg and once-weekly multiple doses 0.2–0.6 mg for 6 weeks; steady-state half-life 124–138 hours.Small early study in healthy participants; sponsor employees were among the authors and the study did not establish long-term clinical or felt-duration outcomes.
Felt duration people report
A product-specific felt-duration window is not established in the inspected English-language community material.
The inspected Reddit thread discussed Phase 3 news, potential competition, cost and expected class side effects rather than verified first-person ecnoglutide use.
General GLP-1 expectations and sponsor adverse-event tables cannot substitute for a first-person onset-and-duration account; gray product identity is also unverified.
- Reddit r/GLP1Australia — Phase 3 results published for ecnoglutide (opens in a new tab)Thread discusses published trial news, hoped-for competition and cost, and speculative side-effect comparisons; it does not contain a verified first-person ecnoglutide course.News discussion and speculation rather than product-verified experience; it cannot establish subjective onset, duration or real-world supply identity.

What people say
- Biased-agonist folklore: “More appetite, less nausea” is the hope; GI still shows up in GLP-1s. forum
- What talk does not prove: A US gray-market vial that matches Sciwind’s product. Human n=1 English logs are thin. forum
- Weight-loss trial bands in the mid-teens percent at ~6–8 months — GLP-1-class, not reta-class headlines. trial
- Glucose / HbA1c in China T2D Phase 3 (0.6 and 1.2 mg weekly vs placebo). trial
Doses people talk about
- US gray milligrams: Not a settled community band as of 2026-09. forum
- T2D trial weekly: 0.6 mg and 1.2 mg in EECOH-1. trial
- Obesity SLIMMER weekly: 1.2 / 1.8 / 2.4 mg. Week-40 means around −9 / −11 / −13%; week-48 2.4 mg ~−15% in company tables. trial
- Framing: Trial milligrams — not a US label, not a research-chem chart everyone agrees on. forum
How it may feel
- Honest thinness: Public English n=1s are not a reta-style Reddit corpus. Expect GLP-1-class nausea/food-noise stories if people get a real vial. forum
- Weeks 1–4: Standard GLP titration nausea/fatigue in the class. forum
- If you feel nothing: Product identity is the first suspicion on a name this new in the US gray market. forum
Around the dose
- Clock: Weekly, same weekday, like sema/tirz habits — if someone actually has it. forum
- Protein / lifting: Same muscle-loss anxiety as every GLP thread. forum
Cycles people discuss
- Not an 8-week blast. forum
- Weekly trial treatment: SLIMMER studied 48 weeks of treatment followed by 7 weeks of safety follow-up; this is a specified trial course, not open-ended treatment. trial
Timing
- Class GI timing: worst after a dose jump, then quieter for some. forum
- Weekly pin is the development clock. trial
More on what it is
- What most people mean: A China-approved weekly GLP-1 that US peptide Twitter treats as a pipeline name, not a fridge staple. forum
- Why it is thin on this map: 2026 US diaries are sparse. Mazdutide/reta/orforglipron steal the English-language oxygen. China T2D and weight-management approvals are the news. forumtrial
- Not: Not semaglutide, not tirzepatide, not retatrutide, not mazdutide. forum
- What it is: Sciwind’s cAMP-biased GLP-1 analogue (XW003). Favors cAMP signaling over β-arrestin in the marketing. Peptide. trial
- Numbers people paste: SLIMMER-type obesity talk ~13.2% weight loss at 40 weeks on 2.4 mg; Phase 2 up to ~14.7% at 26 weeks. EECOH-1 T2D HbA1c drops vs placebo at 0.6/1.2 mg weekly. trial
Stacks
- US stack talk is theoretical — people still on sema/tirz/reta. forum
- Solo GLP in trials. trial
Access talk
- Not a 503A compounding staple in US boards the way sema/tirz were. forum
- Gray-market name should be treated as thin and possibly fake. forum
- China approvals 2026 for diabetes and chronic weight management talk; no US FDA story yet. trial
Storage notes
- China/trial pens vs gray lyophilized powder is the identity problem. forum
- Fridge lore follows other GLP vials if reconstituted. forum
Watch for
- GLP-1 GI class: nausea, constipation, fullness. trialforum
- Thin US identity. A vial labeled XW003 is not automatically Sciwind. forum
- Gallbladder / lean-mass / rebound class worries copy-pasted from sema threads. forum
- Not FDA-approved in the US as of this card. trial
