Good research starts with knowing exactly what you are working with. This page walks through how Resolve presents its products and documentation so you can plan with confidence.
Understanding product formats
Vials. Peptides in vials are lyophilized, meaning they have been freeze-dried into a stable powder and sealed in glass. The amount on the label is the total in the vial. Labs typically reconstitute the powder with a suitable diluent before use in an assay.
Capsules. Capsule listings give two numbers: the amount of compound per capsule and the number of capsules per bottle. Multiply them to find the total contents.
Liquid sprays. Spray listings state the total compound in the bottle and the bottle volume, which together give the concentration of the liquid.
Reading your documentation
A certificate of analysis (COA) records testing results for a specific production lot. When you review one, confirm three things: the compound and quantity match your product, the lot number matches the label on your item, and the report covers the same material you received. Certificates are posted on the COA / Lab Reports page as they become available.
Two of our research articles go deeper on what a report can and cannot tell you: net peptide content, and why it differs from HPLC purity, and endotoxin testing, and how to read an LAL result.
Keeping research in scope
Product pages summarize how a compound has been investigated in published cell and animal studies. That context helps with study design, but it does not describe effects in people, and none of our materials are meant for human or animal use.

What Is Orforglipron? A Non-Peptide GLP-1 Receptor Agonist Explained
Orforglipron activates the GLP-1 receptor without being a peptide at all. Here is how a small molecule reaches a receptor built for a hormone, and why that matters when you plan a study.
