Common questions

What are GLP-1 peptides?

GLP-1 peptides copy a gut hormone that tells your brain you are full and helps keep blood sugar steady. Retatrutide, semaglutide, and tirzepatide are all in this family. They are studied for weight and sold for research use only.

Which weight peptide is strongest?

In studies, retatrutide showed the biggest fat-loss numbers because it hits three targets. Tirzepatide hits two, and semaglutide hits one. Everyone responds a little differently.

Are weight peptides safe?

In research, the most common effects were mild stomach issues that often faded. These peptides are for research use only, not medical use. Talk to a doctor about your own health.
