STRONG EVIDENCE

Strong, human-grade evidence

  • Registered human trials. 514 registered studies on ClinicalTrials.gov, most advanced Phase 4
  • 1 cited source. Cited references provided

A read on the weight of evidence and regulatory standing behind this compound. It is not a safety score, not a purity or quality rating, and not medical advice. It is not a claim that this compound treats, cures, or prevents any condition, and not an endorsement or a recommendation to buy or use it. A low score means the evidence is thin — not that a product is unsafe; a high score means the evidence is strong — not that anyone should take it. PLOBT is independent and takes no money from any vendor; no company can pay to change this score.

What's actually proven

Proven: real but more modest weight loss (roughly 5 to 8%) and blood-sugar control in human trials. Now outperformed by semaglutide and tirzepatide, and it requires daily injection.

Half-life
About 13 hours, requiring daily dosing.
How it is used
Daily subcutaneous injection.

What it is

A GLP-1 receptor agonist, the earlier-generation version of the mechanism used by semaglutide.

What the research says

Weight managementHUMAN TRIALS

Approved as Saxenda in 2014; the first GLP-1 approved specifically for weight.

Type 2 diabetesHUMAN TRIALS

Registered human trials

Live from ClinicalTrials.gov, the US NIH registry of human studies, refreshed daily. Counts studies where Liraglutide is the intervention being tested.

FDA recalls & enforcement

Live from openFDA. Times the FDA required a Liraglutide product to be pulled from the market, with the stated reason. A recall is a specific batch or manufacturing action, not a verdict on the compound itself.

Risks & unknowns

  • GI side effects, similar to other GLP-1 drugs.
  • Daily injection is less convenient than weekly options.
  • Prescription medicine: not for unsupervised use.

Doses reported in studies & protocols

Approved schedules escalate under a prescriber. This is not a recommendation.

Purity reality

Only pharmacy-dispensed product has a verified supply chain.

Verified lab data

None yet. PLOBT does not publish invented purity numbers. Real third-party COA data, mapped to vendor and batch, is in development — and it is the one thing we refuse to fake.
