FAQs

Find answers to your most pressing questions about peptide categories and their usage.

 

What exactly are peptides?


Peptides are short chains of amino acids sp think of them as smaller versions of proteins. They naturally occur in the body and play important roles in processes like cell signaling, hormone regulation, and tissue repair. In scientific research, peptides are used to study those same biological functions more closely.

May support recovery, tissue health, or wellness optimization

Peptides are studied in a wide range of scientific fields including cell regeneration, metabolism, immune signaling, neurobiology, and mitochondrial health. Researchers often explore how specific peptides influence healing, hormone pathways, or cellular performance under various conditions.

Yes. Peptides like BPC‑157 and TB‑500 are frequently studied for their potential roles in tissue regeneration, angiogenesis, and soft tissue recovery. These compounds are of interest in lab models exploring inflammation, tendon support, and post-injury recovery.

Peptides such as Semax and Selank are often explored in neuroscience settings. Studies have focused on their effects on focus, memory, mood modulation, and neuroprotection, making them popular in brain-related research.

Definitely. Compounds like Tesamorelin, AOD‑9604, and Semaglutide are investigated for their impact on fat metabolism, glucose regulation, and appetite signaling. These studies are often centered on energy balance, weight-related hormones, and body recomposition.

Yes peptides like Epitalon, NAD+, and MOTS‑c are commonly found in aging-related studies. Researchers are particularly interested in how they may affect telomere length, mitochondrial efficiency, and oxidative stress key areas in the science of longevity.

No. All peptides sold through Kaia Peptides are for laboratory research use only and are not intended for human consumption, injection, or therapeutic use. Our products are sold strictly for in-vitro studies and controlled research environments.

“Research use only” (RUO) means these products are designed for use in non-human, non-clinical experiments like testing in labs, educational settings, or other investigative purposes. They are not
FDA-approved for use in humans or animals.

High purity = high confidence. We test every batch of peptides for 98%+ purity using third-party labs. That means you’re working with verified, clean compounds crucial for consistent and credible research results.

All our peptides are synthesized in U.S.-based labs using GMP compliant techniques. We follow strict quality control measures and include a Certificate of Analysis (COA) with each batch to back it up.

We do not provide usage instructions, dosing advice, or protocols. Since our products are for research purposes only, we encourage researchers to consult peer-reviewed literature or institutional protocols relevant to their area of study.

Most of our peptides are delivered as lyophilized (freeze-dried) powder in sterile vials. This helps preserve their stability during transit and storage. They’ll need to be reconstituted with an appropriate solvent for research purposes.

Unreconstituted peptides should be stored in a cool, dry place, ideally refrigerated (36–46°F). Once reconstituted, storage requirements depend on the solvent used and your lab’s stability protocols.
