Common questions.

Orders placed before 2 pm ET ship the same day. Domestic US orders arrive in 2–3 business days via cold-chain shipping. All lyophilized peptides are packed with gel ice packs in an insulated mailer.

We currently ship to the US, Canada, UK, and EU. Customs clearance is the buyer's responsibility. Some peptides are restricted in certain jurisdictions — if your order cannot clear customs we will refund the full amount.

$18 flat rate for US orders under $150. Free over $150. International is calculated at checkout.

All shipments arrive in plain, unbranded kraft mailers with no product references on the exterior label. The return address reads "Juno Labs, Inc."

Lyophilized (freeze-dried) peptides should be stored at –20°C in a sealed, desiccated container. Unreconstituted, most Juno peptides remain stable for 24+ months.

Once reconstituted with bacteriostatic water, peptides should be stored at 2–8°C (refrigerated) and used within 30 days for research purposes.

Bacteriostatic water is a pharmaceutical product and is not sold on this site. Qualified researchers can source it separately from clinical suppliers.

All Juno peptides are synthesized at a cGMP-audited facility in the United States. The same class of facility that supplies clinical trial reference material. We do not source from grey-market suppliers.

Research grade peptides are suitable for in vitro laboratory research. They meet or exceed the purity standards of many clinical reference materials, but are not FDA-approved for human use and are sold as reference materials only.

Because we pay for cGMP sourcing, independent HPLC, mass spec, endotoxin testing, and cold-chain shipping on every lot. If a supplier's peptides are significantly cheaper, they are almost certainly skipping one or more of those steps.

All products sold on this site are legal to purchase as reference materials for laboratory research use in the US. They are not approved by the FDA for human use. It is the buyer's responsibility to comply with all applicable local, state, and federal laws.

Because Juno sells peptides as reference materials for in vitro research only. Purchasing these products requires that you represent yourself as a qualified researcher, 21 years of age or older, and that you will use the products exclusively for laboratory research. This is how reference-material suppliers operate across the industry.
