Questions, answered
For laboratory research use only. Not for human consumption.
Are your research compounds third-party tested?
Yes. Independent labs, Janoshik Analytical and US-based labs, test every batch for identity and purity. A rotating panel also checks for heavy metals, endotoxin, and sterility. Each product page links to its own Certificate of Analysis (COA), so you can check the results before you buy.
Who can buy from Life Link Research?
Our research compounds are sold only to qualified researchers aged 21 and over, for laboratory research use only. They are not for human or animal use, and the FDA has not evaluated them for safety or efficacy.
How fast will my order ship?
Orders placed before 2 PM PST ship the same business day from California by UPS 2-Day Air. You’ll get a tracking number by email as soon as your order leaves. Orders over $250 ship free.
Will the vials hold up in transit?
Yes. Our peptides ship as freeze-dried (lyophilized) powder, which stays stable at room temperature for days to a few weeks, so normal transit isn’t a concern. When your order arrives, store the sealed vials somewhere cold, dark, and dry. Read the full storage guidance.
What payment methods do you accept?
We accept Visa, Mastercard, American Express, ACH/eCheck, and Bitcoin. Checkout is secure, and we never sell or share your details beyond what’s needed to process your order.
What if my order arrives damaged, wrong, or doesn’t arrive?
Contact us within 7 days of delivery. For a damaged or wrong item, send photos, and we’ll replace it or refund you in full, including return shipping. For a lost package, we’ll open a claim with the carrier and work with you to resolve it. Unopened items can be returned within 30 days. Read the full policy.
For laboratory research use only. Products on this site are not for human or veterinary use, not for use in diagnostic or therapeutic procedures, and have not been evaluated by the FDA for safety or efficacy. They are supplied strictly to qualified researchers aged 21 and over.
