Every claim here points to proof you can open — not our word for it.
Every batch is identity-confirmed by LC-MS and purity-checked by HPLC before it ships, so the compound and purity are verified against the label — for laboratory research use only.
Every order includes that batch’s Certificate of Analysis, and the lot on your vial matches the report — so you can check the compound and purity against an independent third-party test.
The whole batch is homogenized into one solution, machine-filled to a single dose, and sampled across the run — so your vial reads the same as the one tested.
The same vial every time — sealed, traceable, and clearly marked.
The whole batch becomes one homogenized solution, mixed non-stop, then machine-filled to the exact same dose — so the last vial matches the first.
Every vial ships sealed in a protective tray, traceable to the batch it came from and the Certificate of Analysis for that batch — untampered and accounted for.
Every vial is labeled for laboratory research use only, so what you receive is exactly what the catalog describes — nothing repackaged or relabeled.
US orders ship domestically, go out same-day before 2 PM, and are covered if lost or seized.
US orders dispatch from within the United States, so your package isn’t clearing an international border.
If a package is lost or seized in transit, we reship it (or refund you) — you don’t re-buy.
Refund & returns policyOrders placed before the 2 PM cutoff dispatch the same day — a live, moving operation, not an order frozen in a queue.
Card-backed checkout, a written refund policy, and a team you can reach before you buy.
Check out with Visa, Mastercard, Amex or Apple Pay so your bank’s chargeback rights stay intact — not crypto-only, where a payment can’t be reversed.
Our returns and refund terms are published in plain English on their own page — not improvised over email after you’ve already paid.

How your parcel, your card, and your statement stay yours.
Every order ships in a plain, unbranded mailer — nothing on the box names what’s inside or who it’s from.
Checkout runs on an established payment processor’s PCI-compliant rails — your full card number goes to the processor, not stored on our servers.
The billing descriptor on your card statement is neutral — it doesn’t spell out what you ordered.
At Prime Lab Peptides, one shelf covers a whole research program — GLP-1 peptides like Tirzepatide and Retatrutide, single compounds, and multi-compound blends.
Working at scale? Bulk and 10-vial packs sit right next to oral GLP-1 formats and the bacteriostatic water to pair with them — a full order from one catalog, not four suppliers.
The fast movers stay stocked and restock quickly, so the compound you sourced last month is still there when the next run starts.
