Everything you need to know.

Peptides for research use are sold under a different regulatory category. They are not prescription medications, so a prescription is not required.

Research Use Only (RUO) is a regulatory designation. It means the product is manufactured and sold for research purposes. Catalyst operates within this framework and does not make therapeutic claims or provide medical advice.

No. Catalyst does not provide medical advice, diagnosis, or treatment recommendations. We share what the published science says about the compounds we carry. For questions about personal health, consult a licensed healthcare provider.

Brand-name GLP products are FDA-approved medications sold through pharmacies with a prescription. Catalyst sells research peptides under the RUO framework. The compounds target the same receptors, but the regulatory pathway, pricing structure, and access model are different.

Every batch undergoes identity verification via mass spectrometry, purity analysis via HPLC, and sterility and endotoxin testing. A Certificate of Analysis ships with every order.

GLP-3 RT is currently available in 10mg, 20mg, and 30mg concentrations. The active compound is the same across all three — the difference is dosage per vial.

Store unreconstituted vials in a cool, dry place away from direct sunlight. Once reconstituted, refrigerate at 2–8°C and use within 30 days. Do not freeze reconstituted peptides.

We accept Cash App, Venmo, and PayPal. During checkout, you'll be directed to your preferred payment app with instructions. A screenshot of your payment confirmation completes your order.

Orders are processed within 1–2 business days. Standard shipping is 3–5 business days. Expedited shipping (2-day) is available at checkout. All orders include tracking.

Unopened products may be returned within 30 days of delivery for a full refund. Opened products cannot be returned due to the nature of the compounds. Contact support@catalystexplains.com to initiate a return.

GLP-1 (Glucagon-Like Peptide-1) is a hormone your body naturally produces in response to nutrient intake. It regulates blood sugar, slows digestion, and signals fullness to the brain. GLP-1 agonists mimic this signal, helping regulate appetite and metabolism.

GLP-3 is a triple-agonist peptide that targets three distinct receptors: GLP-1, GIP, and Glucagon. By signaling across three pathways simultaneously, GLP-3 research compounds offer a more comprehensive approach to metabolic regulation than single-receptor compounds.

Safety depends on responsible use, informed self-education, and guidance from qualified healthcare providers. Catalyst provides educational content and access to research compounds, but safety decisions rest with the individual and their medical advisors. We are not a medical provider.
