Liraglutide
FDA APPROVED · RXGLP-1 receptor agonist
Also known as: Victoza, Saxenda
FDA approved and prescription only. Sold as Victoza (type 2 diabetes) and Saxenda (weight management). The first GLP-1 approved for weight (2014).
Strong, human-grade evidence
- Regulatory standing. FDA-approved prescription medicine
- Human trials. Backed by controlled human studies
- 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.
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.
What it is
A GLP-1 receptor agonist, the earlier-generation version of the mechanism used by semaglutide.
What the research says
Approved as Saxenda in 2014; the first GLP-1 approved specifically for weight.
Approved as Victoza for glycaemic control.

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.
Temperature Abuse: product samples were stored at temperatures below 32* F which is not in accordance with storage requirements that could cause a lack of efficacy and damage to the cartridge and pen-injectors.

What people log it for
Descriptive, based on what users track. Not an endorsement or a suggested use.
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.
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.
