Medical disclaimer

LookIndex is an information website. Nothing on it is medical, legal or professional advice, and nothing on it recommends that you use any substance. Talk to a doctor before you start, stop or change any medicine, supplement or treatment.

If something is wrong

If you think you are having a serious reaction, call your local emergency number or go to an emergency department. Tell the doctor exactly what you took, even if it was not prescribed.

You can also report side effects to your regulator:

• FDA MedWatch in the United States
• MHRA Yellow Card in the United Kingdom
• TGA in Australia

What our information is

• Evidence grades are our own editorial judgment of published research. They are not regulator ratings and they do not mean a product is safe.
• Legal status is a general summary. Laws differ by place and change often. Check the rules where you live.
• Costs are approximate, in US dollars, and dated.
• We can make mistakes, and research moves on. Always check the sources listed on each page.

What we do not do

We do not sell peptides, link to sellers, take sponsorship, use affiliate links or publish doses, cycles, stacks or protocols. If we mention a brand name, it is only so you can identify a medicine or read a regulator's warning.

LookIndex is for adults aged 18 and over.
