2-peptide research blend in one vial: Cagrilintide + Semaglutide. Novo Nordisk's fixed-dose combination of the amylin analog cagrilintide and the GLP-1 receptor agonist semaglutide — a once-weekly obesity injection that pairs two complementary appetite pathways, currently under FDA review.
Also known as: Cagrilintide/semaglutide
A blend has one whole-vial purity, but the number that decides what you're holding is the net content of each component — an HPLC run resolves a separate peak for each. So we verify CagriSema component by component. Each links to its own compound page, where its full independent testing lives.
| Component | Typical mg | Role in the blend | Verified purity | |
|---|---|---|---|---|
| Cagrilintide | 2.4 mg | Long-acting amylin analog — enhances satiety signalling | 99.6% · 276 tests | View testing → |
| Semaglutide | 2.4 mg | GLP-1 receptor agonist — reduces appetite, slows gastric emptying | 99.7% · 446 tests | View testing → |
Composition varies by vendor. The components above are consistent across shops, but the milligrams can differ — always dose by the individual component amounts printed on your vial, never by a generic “blend dose.”
A blend is the single hardest product to trust — the whole-vial purity tells you the material is clean, but not whether every peptide is present in the right amount. Two questions decide that, and both are answerable in a lab.
Mass spec (or a clean HPLC peak per compound) confirms each peptide is in the vial — not one short, not a cheaper substitute standing in for the expensive one.
Tested milligrams vs. labelled milligrams, per component. This is where blends fail quietly — one component underdosed to pad margin while the vial still “contains” everything.
Tests run on a CagriSema vial as sold — broken down per component. This is the data no shop and no competitor publishes.

Until more CagriSema vials are tested, the strongest signal is how each component performs in single-compound testing across the shops we track. Tap any card for its full data.

CagriSema is a genuine Novo Nordisk fixed-dose combination — not a gray-market stack — pairing cagrilintide (a long-acting amylin analog) with semaglutide (the GLP-1 receptor agonist marketed as Wegovy/Ozempic) in a single once-weekly subcutaneous injection for weight management. Unlike the other blends in this section, it is a formally developed pharmaceutical — but as of August 18, 2026 it is still under FDA review and not approved in the US or EU.
The combination targets appetite through two complementary systems at once: semaglutide's GLP-1 pathway reduces appetite and slows gastric emptying, while cagrilintide's amylin pathway enhances satiety signaling — and in trials the pair produced greater weight loss than either component alone, evidence of genuine synergy. In REDEFINE 1 (n=3,417), the published primary result is 20.4% average weight loss at 68 weeks on the treatment-policy estimand — versus 14.9% for semaglutide 2.4 mg alone, 11.5% for cagrilintide alone, and 3.0% for placebo. On the trial-product estimand (participants adhering to treatment), the figures are 22.7% for CagriSema versus 16.1%, 11.8%, and 2.3% respectively. REIMAGINE 2 — topline reported February 2026 and since published in The Lancet Diabetes & Endocrinology — where CagriSema showed a 1.91-percentage-point HbA1c reduction and 14.2% weight loss, superior to semaglutide 2.4 mg alone in adults with type 2 diabetes.
CagriSema is an investigational combination: Novo Nordisk filed a New Drug Application with the FDA on 18 December 2025 (based on REDEFINE 1 and REDEFINE 2), the agency's decision is expected in Q4 2026 — around October on the standard ten-month review clock, though no PDUFA date has been publicly confirmed — and it remains unapproved in both the US and EU; notably, in the REDEFINE 4 head-to-head trial (n=809, open-label, 84 weeks) CagriSema delivered 23.0% weight loss versus 25.5% for tirzepatide 15 mg (efficacy estimand; 20.2% vs 23.6% on the treatment-regimen estimand) and did not meet its primary endpoint of noninferiority to tirzepatide — figures from Novo Nordisk's February 23, 2026 topline announcement, not yet peer-reviewed. Higher-dose data from REDEFINE 11 is expected in the first half of 2027. Evidence level: Phase 3 complete; under FDA review; not approved (verified August 18, 2026).
Because CagriSema is not yet an approved, dispensable product, anything sold outside a clinical trial is unapproved material of uncertain identity — and a fixed two-peptide combination is exactly the kind of product where mass-spec identity and HPLC purity for both components matter. Peptigrity collects independent third-party Certificates of Analysis from shops' official channels and verifies each for authenticity before publishing — because shops choose which COAs to publish, results reflect the batches made public rather than every production batch, a selection bias we state openly. A community-funded Testing Grant to purchase and test vials anonymously is in development. The trust score weights lab purity and reviews equally (50/50). See how to read lab results.

22.7% average weight loss at 68 weeks in REDEFINE 1 (trial-product estimand; about 20.4% on the treatment-policy estimand) — more than either component alone — though it delivered 23% but missed noninferiority versus tirzepatide in the separate REDEFINE 4 head-to-head.
