Precision
has a pulse.
Research-grade peptides with the paperwork to prove it. Every lot independently tested, every vial lot-coded, every COA public.
Fully specified. Nothing vague.
CAS number, sequence, formula and molecular weight on every product page, so you know exactly what is in the vial before it ships.
Not “99%+.”
The actual number.
Most vendors print the same purity claim on everything. We publish the measured HPLC result for every lot, tied to the lot number printed on the vial. If a lot misses spec, it does not ship.
- HPLC purity measured and published for every lot
- Mass spec identity confirms the right molecule is in the vial
- Release threshold ≥98.0% (HPLC) or the lot is rejected
- Lot lookup matches any vial to its report in seconds
Illustrative layout. Real chromatograms and results are published on each lot's COA.
From synthesis to your bench,
nothing skipped.
Synthesized
Solid-phase synthesis, purified and lyophilized for stability in storage and transit.
Independently tested
Third-party HPLC and mass spectrometry on every lot before it is released for sale.
Lot-coded
A lot number printed on every vial and matched to a COA anyone can look up.
Shipped and tracked
Packed discreetly, shipped from the United States with tracking on every order.
Built like a lab supplier.
Not a supplement shop.

How does ordering work?
Add compounds to your cart and submit an order request at checkout. No payment is taken on the site. We confirm stock and email you a secure payment link the same business day. Your order ships once payment clears.
How do you test your peptides?
Every lot is tested by an independent third-party laboratory before release: HPLC for purity and mass spectrometry to confirm identity. Lots below our release threshold of ≥98.0% (HPLC) are rejected.
Where do I find the COA for my vial?
Every vial is printed with a lot number. Enter it on our Lab Testing page to pull up the matching certificate of analysis. Each product page also shows its current lot.
Can these products be used in people or animals?
No. Every PeppedCo product is sold strictly for in-vitro laboratory research. They are not for human or veterinary use and are not drugs, foods, dietary supplements or cosmetics.
When will my order ship?
Orders ship the same business day when payment clears before 2 PM ET, Monday to Friday. Otherwise they ship the next business day. Tracking is emailed as soon as the label is created.
New lots and reports, first.
One email when a lot clears testing or a compound restocks. Join now and get 10% off your first order.
