Peptides are short chains of amino acids linked by peptide bonds. They serve as biological messengers that regulate various physiological functions such as metabolism, immune response, and cellular repair. Peptides are widely researched in fields like regenerative medicine, anti-aging, and metabolic studies.

Peptides are shorter in length than proteins, typically consisting of 2-50 amino acids, while proteins are composed of longer chains, often exceeding 50 amino acids. Peptides usually act as signaling molecules, whereas proteins have structural or enzymatic roles in the body.

Bilt Peptides offers a wide range of research peptides, categorized into areas such as:

GLP-1 (e.g., GLP-1 (S), GLP-2 (T), GLP-3 (R)
Anti-Aging (e.g., Epithalon, GHK-cu, NAD+)
Growth Hormone (e.g., CJC-1295, Ipamorelin, Tesamorlin)
Cognitive & Neuro (e.g., Selank, DSIP)
Skin & Hair (e.g., GHK-Cu, BPC-157/TB-500 blends)
Immune & Inflammatory (e.g., Thymosin Alpha-1, TB-500, LL-37)
Libido & Reproduction (e.g., Kisspeptin-10, Oxytocin)

All peptides offered by Bilt Peptides are synthetically produced using state-of-the-art peptide synthesis technology. This ensures high purity, batch consistency, and stability for research applications.

Our peptides have a purity level of ≥99%, verified through High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS) analysis.

Every batch is tested for purity, molecular integrity, and contaminants, with results documented in a Certificate of Analysis (CoA).

Yes, each batch of peptides comes with a Certificate of Analysis (CoA) that verifies its purity, molecular composition, and batch-specific testing results. These CoA’s are available in our COA Library on the website.

Before reconstitution: Store lyophilized peptides at -20°C (-4°F) for long-term stability.

After reconstitution: Keep at 2-8°C (36-46°F) and use promptly to maintain integrity.

The appropriate solvent depends on the peptide’s properties:

Bacteriostatic Water (BW): Commonly used for most peptides.
Acetic Acid (0.6% or 1%): Recommended for peptides with solubility issues.
DMSO (Dimethyl Sulfoxide): Used for specific hydrophobic peptides.
Note: We offer bacteriostatic water in our shop for peptide reconstitution.
