What types of peptides do you manufacture?
We specialize in a variety of high-purity peptides, including custom peptides, research-grade peptides, cosmetic peptides, and peptide lyophilized powders and raw materials for pharmaceutical applications.
What is the purity level of your peptides?
Our peptides are typically ≥99% pure, and we provide detailed COA (Certificate of Analysis).
Why are your products labeled as "Research Use Only" (RUO)?
In the United States, only licensed pharmacies can compound peptides and resell them for human use.
Peptides in powder form can still be sold, however, they must be marked “Research Use Only,” for legal and liability reasons.
PLEASE be aware that self administering “research” peptides could be dangerous! There’s a reason certain compounds are available ONLY under the careful supervision of a doctor. We do not want to see anyone harmed by misusing our products.
Furthermore, we cannot provide medical advice of any kind. Please be safe.
