What are weight loss peptides?

Weight loss peptides is a broad label for compounds studied in obesity and metabolism research. They work through quite different routes. The GLP-1 compounds and cagrilintide act on gut hormone receptors and appetite. AOD-9604 is a growth hormone fragment studied for fat breakdown. MOTS-c acts on muscle metabolism through AMPK.

The capsule compounds aren’t peptides, but they sit in the same research area. 5-Amino-1MQ blocks the NNMT enzyme in fat cells, SLU-PP-332 switches on exercise-like gene programs in muscle, tesofensine is a reuptake inhibitor, and ATX-304 keeps AMPK active.

How to choose weight loss peptides

If your work is on appetite and gut hormones, start with the GLP-1 peptides. For fat metabolism without the incretin pathway, look at AOD-9604 or 5-Amino-1MQ. For muscle energy and endurance models, MOTS-c and SLU-PP-332 are the usual picks.

Capsules suit oral-route studies and skip reconstitution. Vials are the format for injectable-route work.

Weight loss peptides: formats and prices

There are 31 products in this range: 26 single-peptide vials and five capsule bottles. Prices run from $39.90 to $589.90. Every product page lists the amount, the format and the SKU, so you can compare like for like before you order.

Lab testing for our weight loss peptides

Most of our product pages carry the lab paperwork right in the photos: certificates of analysis with HPLC purity, and for many peptides an endotoxin report and an independent Janoshik test you can verify online. Where a report was run on a different vial size of the same peptide, the product page says so.

Store sealed vials in the fridge, or the freezer for long-term storage, and reconstitute with bacteriostatic water. Every vial page lists the concentration you’ll get for each volume of water.

Weight loss peptides FAQ

Are your weight loss peptides in stock?

Yes. Everything listed here is in stock now.

Are weight loss peptides for human use?

No. Everything we sell is for laboratory research only and isn’t approved for human or veterinary use.

How do I pick a size?

Bigger vials cost less per milligram. Smaller ones make sense for short projects, since less sits open in the fridge. Each product page compares the sizes.

Do I need anything else?

Vials need bacteriostatic water to reconstitute. Capsules are ready to use.
