By accessing longevity48.com or any related subdomain, product, email, or Telegram bot operated by The Longevity 48™ ("Longevity48", "we", "us", "our"), you agree to be bound by these Terms of Service and by our Privacy Policy and Risk Disclosure. If you do not agree, stop using the service immediately.
You must be at least 21 years of age to use this website or purchase any product offered through it. You confirm you are of legal age in your jurisdiction to possess, store, and handle the research-use compounds we discuss. You are solely responsible for determining whether local law permits your use of those compounds.
Peptides and compounds referenced on this site are supplied as research chemicals for in-vitro and laboratory investigation only. They are not sold as drugs, dietary supplements, cosmetics, or any product intended for human or veterinary consumption. We make no representation that any compound is safe or effective for any particular use.
Nothing on this website constitutes medical advice. The quiz, encyclopedia, calculator, stacks, protocol templates, and AI assistant are all educational tools. They are not a substitute for a consultation with a licensed clinician. Always consult a qualified medical professional before beginning, modifying, or discontinuing any protocol — especially if you take prescription medication, have a diagnosed condition, are pregnant or breastfeeding, or are under the care of a specialist.
Some features (Client Portal, Order history, Telegram bot linkage, Admin console) require an account. You are responsible for the security of your login credentials and for all activity under your account. We may suspend or terminate your account for violation of these Terms, suspected fraud, abuse of the AI assistant, or regulatory risk.
We ship via partnered couriers. You accept the risk of loss once a tracking number is issued; we will assist with carrier claims where available but cannot guarantee delivery or reimbursement for items lost or seized in transit. Because our products are research chemicals shipped internationally, all sales are final and we do not accept returns on opened or unsealed vials. In the rare event of a product defect confirmed by us, we will offer a replacement or a store credit at our discretion.
Crypto transactions are irreversible. We watch for incoming USDC payments across supported chains (Base, Arbitrum, Optimism, Polygon, Ethereum) and match them to orders by exact amount. If you send a different amount, send after the 15-minute window, or send on a different token or chain, your order will not auto-complete. Contact support with your transaction hash and we will reconcile manually; refunds in crypto require a wallet address you control and may incur network fees.
All content on this site — brand marks, product designs, encyclopedia entries, protocol templates, written copy, quiz logic, and the Longevity 48™ wordmark — is owned by Longevity48 or its licensors. You may read it for personal, non-commercial purposes. You may not copy, redistribute, scrape, or create derivative works without our written permission.
The site and all content are provided "as is" and "as available", without warranty of any kind, express or implied. We do not warrant that the site will be uninterrupted, secure, or error-free, nor that any content will meet your requirements.
To the fullest extent permitted by law, Longevity48, its officers, employees, and partners shall not be liable for any indirect, incidental, special, consequential, punitive, or exemplary damages arising from your use of the site, your purchase or handling of any product, or your reliance on any content.
We may revise these Terms at any time. Material changes will be announced via email to active account holders and via a banner on the site. Continued use of the site after notice constitutes acceptance.

The products referenced here are supplied for in-vitro and laboratory research only. They are not drugs. They have not been evaluated by the FDA or any equivalent regulator for human consumption. The research literature we cite is incomplete, often preclinical, and may not translate to any particular person's biology.
Nothing on this site — including the Peptide Finder quiz, encyclopedia entries, dosage calculator, stack recommendations, Telegram AI assistant, or email responses — constitutes medical advice, diagnosis, or treatment. The quiz is a sorting tool, not a prescription. A ranked shortlist does not mean a peptide is appropriate for your body, your condition, or your goals.
The legal status of peptides varies by country, state, and province. In many jurisdictions these compounds are legal to purchase for research use but illegal to use on humans. Some are banned in competitive sport (WADA S2 class includes IGF-1 LR3, GHRPs, CJC-1295, and most growth-hormone releasers). You are responsible for knowing and complying with your local law.
We provide a product and we provide educational content. We do not supervise your protocol, run your labs, or practice medicine. We do not have a doctor–patient relationship with you. You hold us harmless for the consequences of any decision you make about peptide use, including decisions informed by content on this site.
If any of the following apply, please do not order and consult a clinician instead:
By entering this site, by submitting the quiz, or by placing an order, you confirm you have read this Risk Disclosure, understand the stated risks, and accept full and sole responsibility for your choices.
