- • not dosing guidance
- • not injection or reconstitution guidance
- • not a substitute for a registered pharmacist or doctor

General information
The information on Peptide Authority is for educational and informational purposes only. It is not intended as, and should not be construed as, medical advice, diagnosis, treatment, or a substitute for professional medical consultation.
Nothing on this website should be interpreted as an endorsement or recommendation to use any peptide compound for any purpose. The content reflects published research and public regulator statements at the time of writing, and may not reflect the current state of medical or regulatory practice.
Not medical advice
The content on this website does not establish a doctor-patient relationship. Always seek the advice of a qualified healthcare professional with any questions regarding a medical condition, treatment, or medication. Never disregard professional medical advice or delay seeking it because of something you have read on this website.
If you are considering using any peptide compound, you must consult with a registered medical practitioner who can evaluate your individual circumstances, medical history, and potential interactions with existing medications.
No dosing or injection guidance
We do not provide instructions on how to dose, reconstitute, inject, cycle, or stack peptides. The Reconstitution Maths Reference tool on this site is an educational maths utility for pre-existing pharmacy practice, not a dosing tool.
For prescribed medicines, follow the directions of your prescriber and the Patient Information Leaflet (PIL). For unlicensed compounds, this site is not a source of use instructions of any kind.
Unlicensed peptide warning
Many compounds discussed on this website are not approved medicines in the United Kingdom or European Union for human therapeutic use. Labelling such as “research use only” or “not for human consumption” does not by itself make human-use claims lawful, safe, or evidence-based. Research findings presented may be based on:
- In vitro (cell-based) studies that may not translate to humans
- Animal studies with limited applicability to human physiology
- Early-phase clinical trials with small sample sizes
- Preliminary, unpublished, or non-peer-reviewed research data
The level of evidence is shown throughout our content using our public evidence grading system.
Prescription-only medicine warning
Some peptides discussed on this site — including semaglutide, tirzepatide, liraglutide, and related GLP-1 receptor agonists — are prescription-only medicines (UK POM) when used as medicines. Lawful access is through a registered UK prescriber and a regulated pharmacy. Counterfeit and contaminated weight-loss pens are a serious UK safety issue. See our fake pen safety page.
Regulatory status
Regulatory status information on this site is summarised from public regulator statements and is accurate at the time of writing, but may change. Users are responsible for understanding and complying with current law and regulation in their jurisdiction. See our UK regulatory methodology.
No liability
Peptide Authority, its editors, and contributors accept no responsibility or liability for any consequences arising directly or indirectly from the use of, or reliance upon, the information on this website. Use of this website is at your own risk.
