Every product sold by Prosper Labs is intended strictly for laboratory research and educational purposes. Our products are not for human or animal consumption and are not intended to diagnose, treat, cure, or prevent any condition. By purchasing, researchers confirm the materials will be used exclusively in a controlled laboratory research setting.
This policy applies to every product, page, and document on this site. If anything here is unclear, contact us before ordering.
Every batch is analyzed by independent, accredited U.S. laboratories, and Certificates of Analysis are published so researchers can review testing documentation before purchasing. COAs are available in our library and directly on product pages where documentation exists for that batch.
Each product page lists the compound name, available strength options, labeling details, and any documentation available for that product — including purity data and batch testing where applicable — so researchers can evaluate materials before ordering.
Orders are processed quickly — orders placed by 2PM typically ship the same business day. All packages ship in plain, discreet packaging with tracking provided. U.S. orders ship UPS 2nd Day Air. International orders ship DHL (1–3 days) or USPS (6–10 days).
Research materials should be handled only by qualified researchers following their institution's laboratory protocols: store as indicated on the label, keep containers sealed and clearly labeled, and follow standard laboratory safety practices for storage and disposal.
Raw peptide powder is purchased from qualified suppliers, domestic and international, against an incoming specification. Everything after that happens here: compounding, filling, lyophilization, capping, labeling, lot assignment and release testing are all performed at our Arizona facility, and every order ships from that same building.
Raw peptide powder is purchased against a written incoming specification from qualified suppliers, both domestic and international. Supplier qualification, the incoming spec and the country of origin for each lot are recorded before the material is accepted.
Nothing goes into production on a supplier certificate alone. Incoming material is independently verified for identity and purity by HPLC, and for endotoxin by LAL to USP <85>, before it is released to the fill line.
Compounding, filling, lyophilization, stoppering, capping and labeling are all performed in-house. This is where the finished product is actually made — the vial you receive is assembled, dried and sealed here, not repackaged from a finished import.
Every finished lot gets its own number and its own Certificate of Analysis. Release testing is performed by independent, accredited U.S. laboratories, and the report is published to the COA library against that lot number.
Released lots are held sealed under their own storage condition — lyophilized material at −20°C, protected from light and moisture — right up until the order is picked, rather than sitting at ambient in a warehouse waiting to be sold.
Orders are picked, packed and shipped from the same facility that made them — no third-party warehouse, no drop-shipper, no transshipment. Orders placed before the daily cutoff go out the same business day in plain, unbranded packaging.
We would rather tell you exactly what happens where than hide behind a flag graphic. Plenty of suppliers put “Made in the USA” on a page while importing a finished, filled vial and doing nothing to it but applying a label. That is not what happens here.
Made in the USA from domestic and imported raw material — compounded, filled, lyophilized, labeled and lot-tested at our Arizona facility.
Where raw material for a given lot is imported, we say so rather than implying the peptide itself was synthesized domestically. The country of origin for the raw material used in any lot is available on request, and is recorded against that lot in our batch records.
This category has a credibility problem, and it is self-inflicted. Vials arrive with no lot number, no testing, and a purity figure that traces back to nothing. We built Prosper Labs the opposite way round: every claim on this site is supposed to be checkable against a document, and the ones that are not checkable we simply do not make.
A purity figure is meaningless without a lot number attached to it. Every finished lot carries its own identifier, its own HPLC report and its own LAL endotoxin result, all published in the COA library and reachable from the product page. If a report does not exist for a lot, we do not claim a number for it.
Release testing is performed by third-party accredited U.S. laboratories rather than in-house, because a supplier grading its own homework is not verification. Identity and purity by HPLC, endotoxin by LAL to USP <85>.
Because the fill line and the shipping bench are in the same building, the chain of custody between the lot being sealed and the box leaving the door is short and documented. Nothing is transshipped, and no third-party warehouse handles the product.
Everything here is sold as a research reagent for in-vitro laboratory work by qualified professionals. You will not find dosing guidance, protocols, outcome claims or human-use language anywhere on this site, because none of that belongs on a research-reagent catalogue. If that is what you are looking for, we are not the right supplier.
Every product page states the molecular formula, molecular weight, physical form and the basis for the purity figure. A research reagent that will not tell you what molecule is in the vial is not a research reagent.
Lyophilized peptides are stored sealed at −20°C, protected from light and moisture. Copper complexes and oxidation-sensitive material get light protection on top of that, and the preserved diluent is stored at room temperature and must not be frozen. Each product states its own condition rather than a generic line.
