Peptide Research, Out in the Open.

Q: 1. Which products does Open Science offer?

Our initial catalog includes five research products: GLP-2 (Tirzepatide) GLP-3 (Retatrutide) GHK-Cu Lipo-C with B-12 Bacteriostatic Water

Q: 2. Are your products intended for human or veterinary use?

No. Open Science products are supplied strictly for laboratory research and are not intended for human or veterinary use.

Q: 3. What purity level do your peptides have?

Every peptide has a minimum purity of 99%. Consult the corresponding Certificate of Analysis for batch-specific results.

Q: 4. Are your peptides lyophilized?

Yes. All Open Science peptide products are supplied as lyophilized powder. Lipo-C with B-12 and Bacteriostatic Water are supplied in liquid form.

Q: 1. What does Open Science test for?

Products are tested for potency, purity, and endotoxins. Batch-specific results are documented in the corresponding Certificate of Analysis.

Q: 2. Are your products independently tested?

Yes. Products are tested by an independent laboratory before being offered for sale.

Q: 3. What is a Certificate of Analysis?

A Certificate of Analysis is a document containing the laboratory results associated with a specific product batch.

Q: 4. Where can I find the Certificate of Analysis?

The Certificate of Analysis is available directly on each product page. Our centralized Research Library is coming soon.

Q: 5. Can test results vary between batches?

Yes. Results may vary slightly between batches. Always consult the Certificate of Analysis associated with the specific product being purchased.

Q: 1. How do I place an order?

Select your products, add them to your cart, and complete the secure checkout process.

The Research Essentials, Without the Guesswork.

A focused collection today, with more peptides coming soon. Every batch is tested by HPLC and mass spectrometry at independent U.S. laboratories, with potency, purity, and endotoxin results documented in its COA.

Triple-Action

Retatrutide

$199.99

A 39-amino acid triple agonist peptide targeting GIP, GLP-1, and glucagon receptors, studied for metabolic regulation and body composition in clinical research.

Metabolic Compound

Tirzepatide

$109.99

A 39-residue synthetic linear peptide that acts as a dual agonist at both the GIP and GLP-1 receptors. A C20 fatty diacid chain at Lys-20 drives albumin binding for a once-weekly circulation profile.

Metabolic Compound

Lipo-C

$49.99

A long-acting GLP-1 receptor agonist: a 31-residue analog of human GLP-1 (~94% sequence homology) carrying a C18 fatty diacid chain via a linker that drives reversible albumin binding for extended circulation.

Metabolic Compound

GHK-Cu

$29.99

A naturally occurring copper tripeptide that promotes tissue remodeling, wound healing, and collagen synthesis in animal and in vitro studies.

Cellular Peptide Blend

KLOW

$99.99

A quad-peptide combination of BPC-157, TB-500, GHK-Cu, and KPV targeting complementary angiogenic, cellular migration, extracellular matrix remodeling, and anti-inflammatory pathways in preclinical research.

Research Peptide

Melanotan I

$29.99

A 13-amino acid linear peptide analog of alpha-melanocyte-stimulating hormone that selectively activates MC1R to stimulate eumelanin synthesis and photoprotective pathways in clinical research.
