Documented compounds for serious research.
Lyophilized research-grade peptides in sealed, batch-labeled vials — HPLC for purity, ESI mass spectrometry for identity, and a batch-matched Certificate of Analysis with every order.
Synthesized and tested in the USA
Compounds are produced in US facilities and analysed by an independent third-party laboratory before a lot is released.
Two methods, every lot
HPLC reports purity as a percentage of total peak area; mass spectrometry confirms the molecular weight matches the target sequence. A lot that misses either specification is not released.
Paperwork that matches the vial
The lot number printed on your vial matches the Certificate of Analysis in the box. Judge any supplier — including us — by whether the document could only describe the vial in your hand.
Featured compounds
Research compounds, ready to ship
Lyophilized peptides in sealed, batch-labeled vials. Filter by category, search by compound or SKU, and open any product for its full specification.
Lyophilized powder needs a diluent.
Research peptides ship as a dry cake. Bacteriostatic water (0.9% benzyl alcohol, 10 mL) is the standard laboratory diluent used to reconstitute them at the bench.
From synthesis to sealed vial
Every lot moves through the same pipeline before it reaches the catalog — and every claim on this page is one you can check against the paperwork in your box.
Solid-phase synthesis
Peptides are assembled residue by residue in US production facilities under controlled conditions.
HPLC purification and assay
Preparative HPLC isolates the target sequence; analytical HPLC reports purity as a percentage of total peak area against the product specification.
Mass-spec identity
ESI mass spectrometry confirms the observed molecular weight matches the target sequence. Purity without identity proves nothing.
Lyophilization and sealing
Filtered, freeze-dried and sealed in batch-labeled glass vials with the lot number printed on the label.
Certificate of Analysis
The lot is released with a COA that names the test date, method, specification and measured result for that batch — and that document ships with the order.
A COA is not marketing. It says what was tested, by what method, on what date, against what specification, for one specific batch. Ask for the COA of any lot before you order — request a COA or read how to verify a certificate.
A certificate documents laboratory testing of a batch. It is not evidence of suitability for use in or on any human or animal, and nothing in our catalog is approved for such use.
Reconstitution calculator
Concentration and syringe-unit math for preparing research solutions at the bench.
Laboratory reference only. This is volumetric arithmetic, not dosing guidance — Arkana products are not for human or veterinary use.
US synthesis.
Traceable paperwork.
Our compounds are synthesized and tested in the United States. Every vial carries a batch identifier linked to its analytical results and its Certificate of Analysis — any vial traces back to its analysis, and any analysis traces forward to the vials it released.
No protocol guidance
We publish no dosing, administration, cycling or stacking information for living subjects, and we decline to provide it on request. Storage and handling guidance is for laboratory purposes only.
No outcome claims
Our copy describes chemical identity, purity, method and research context — never expected effects in a living subject.
Conditions of sale
Ordering requires an express warranty that the buyer is purchasing for in-vitro research and will not administer or resell these materials for use in any human or animal.
