Frequently asked
Questions, answered
Everything researchers ask about ordering, testing, shipping and storage. If your question isn’t here, our team is one message away.
Ordering & delivery
How fast is shipping?
Orders confirmed before our daily cut-off are dispatched within 1–2 business days from our US facility. Tracking is provided on every order.
Do you ship internationally?
Yes — we offer fast worldwide shipping. Delivery times and any import requirements vary by destination; tracking is provided on every shipment.
How do I track my order?
A tracking number is emailed as soon as your order is dispatched. You can also view order status any time from your account area.
Can I return an order?
Unopened products can be returned within 14 days of delivery. Full details are set out on our Refund Policy page.
Products & testing
Are these products safe for human use?
No. Every product Isla Longevity supplies is sold strictly for in-vitro laboratory research only — never for human or veterinary use, consumption, or injection. Products must be handled by qualified personnel in an appropriate laboratory environment.
Are your products third-party tested?
Yes. Every batch is independently analysed by Freedom Diagnostics for identity and purity, and the certificates of analysis are published openly on our COAs page — not hidden behind a request form.
How should compounds be stored?
Store lyophilised powder cool, dry and away from direct light. Once reconstituted with ISLA-H20, refrigerate at 2–8°C and avoid repeated freeze–thaw cycles to preserve integrity.
Do you supply ISLA-H20 and syringes?
ISLA-H20 is available separately on our shop for laboratory reconstitution. Syringes are not included — researchers should source these through their standard laboratory supplier.
Payment & account
What payment methods do you accept?
We currently accept Zelle, Venmo and Cash App. Choose your method at checkout and you will be given the payment details along with your order number. Orders are dispatched as soon as payment clears, usually the same business day.
Do I need an account to order?
No — guest checkout is available. Creating an account lets you track orders and reorder faster, but it isn’t required to purchase.
Still have a question?
Our US-based team replies within one business day.
