What are weight loss peptides?

Weight loss peptides is a broad label for compounds studied in obesity and metabolism research. They work in quite different ways. The GLP-1 family acts on gut hormone receptors that control appetite and insulin. AOD-9604 and Fragment 176-191 are pieces of growth hormone studied for fat breakdown. MOTS-c and 5-Amino-1MQ act inside the cell, on mitochondria and on the enzyme NNMT.

That spread is useful. A lab can compare a hormone-driven approach with a cell-energy approach in the same model, using compounds from one supplier.

How to choose weight loss peptides

Decide whether you’re studying appetite and hormones, which points to the GLP-1 and amylin compounds, or fat tissue and cell energy, which points to the growth hormone fragments, MOTS-c and 5-Amino-1MQ.

Fragment 176-191 2mg has a buy 1 get 1 free deal and bulk packs, which makes it the cheapest way into this area for longer studies.

Weight loss peptides: formats and prices

There are 11 products in this range: ten freeze-dried vials and one blend vial. Prices run from $32.47 to $194.99 for a single item. Three of them also come with a free-item deal or bulk packs, which you pick from the quantity dropdown on the product page. Every product page lists the amount, the format, the tested purity and the SKU, so you can compare like for like before you order.

Purity and testing for our weight loss peptides

Each product page shows the tested purity for the current batch, measured by HPLC with mass spectrometry, and most of our peptides test at 99% or higher. Every vial is labeled with the compound, the amount and a batch number. The certificate of analysis is filed under that number, and we’ll email it to you on request.

Store sealed vials in the freezer, or the fridge for shorter stretches, and reconstitute with sterile bacteriostatic water. Every vial page lists the concentration you’ll get for each volume. Our vial storage case keeps ten vials upright and together.
