Starktides was founded on a single principle: researchers deserve compounds they can trust. Every peptide we supply undergoes rigorous independent testing before it reaches your lab. We don't cut corners on quality, documentation, or transparency — because your research depends on it.
To provide the scientific research community with access to the highest-purity peptides, supported by transparent documentation and rigorous third-party testing. We exist to remove barriers between researchers and reliable compounds.
Every batch is independently tested before it's offered for sale. We publish lot-specific Certificates of Analysis, HPLC data, and mass spectrometry reports — so you can verify exactly what you're working with.
All products are formulated and supplied strictly for in vitro and laboratory research use. We maintain strict research-use-only positioning and work exclusively with qualified researchers and institutions.
Unlike generic suppliers, every compound we offer is batch-verified with third-party documentation. We believe transparency is not optional — it's the foundation of scientific integrity.
Peptides are synthesized using solid-phase peptide synthesis (SPPS) by certified manufacturing partners operating under current Good Manufacturing Practice (cGMP) guidelines.
Every batch is sent to an independent, ISO/IEC 17025:2017 accredited laboratory for HPLC purity analysis and electrospray ionization mass spectrometry (ESI-MS) molecular weight confirmation.
Upon passing all analytical tests, a lot-specific Certificate of Analysis is issued by the third-party laboratory documenting purity, identity, endotoxin levels, and sterility results.
Compounds are lyophilized, sealed under inert atmosphere, and stored at -20°C in light-proof packaging until dispatch. Packaging is tamper-evident and labeled with lot number and expiry.
All orders ship with full tracking in insulated, temperature-controlled packaging. COA documentation is included with every shipment.
Minimum ≥98.0% purity as verified by reversed-phase HPLC at 220nm. Most compounds exceed 99% purity.
Every compound confirmed by ESI-MS with molecular weight matching theoretical value within ±0.5 Da.
Bacterial endotoxin testing by LAL Gel-Clot method per USP <85>. Specification: <1.0 EU/mg.
Sterility verified by membrane filtration per USP <71>. No microbial growth confirmed for all lots.
ICP-MS analysis confirms total heavy metals below 10 ppm, with individual elements (As, Cd, Hg, Pb) below ICH Q3D limits.
Lot-specific COA, HPLC chromatogram, and MS spectrum available for every batch. Full traceability from synthesis to delivery.
All Starktides products are manufactured for in vitro research and laboratory use exclusively. Not for human or veterinary use. Not a drug, food, or cosmetic. Not intended for diagnostic purposes.

Starktides supplies high-purity synthetic peptides to qualified research institutions and laboratories. Every compound is rigorously verified — for science that demands certainty.
For Research Use Only. All products sold by Starktides are intended exclusively for in vitro and laboratory research. Not for human or veterinary use, not for clinical or diagnostic applications. Qualified researchers and institutions only. Must be 21+.
Research-grade peptides synthesized to exacting purity standards, verified by HPLC and mass spectrometry. All products are for research use only.
At Starktides, we believe access to reliable research-grade materials should not be limited by cost or availability. Our mission is to provide the research community with verified, consistent compounds backed by real documentation.
Every compound undergoes HPLC analysis and mass spectrometry confirmation before release. A full Certificate of Analysis is provided with every order.
We source from manufacturers who maintain strict production standards and batch traceability. What is on the label matches what is in the vial — every time.
Temperature-sensitive compounds are shipped on dry ice using validated cold-chain packaging. Stability from our facility to your lab is a commitment.
We stand behind every order. Our team is responsive, our policies are clear, and we operate with the same standards we expect from our suppliers.
The integrity of your research depends on the integrity of your reagents. Our standards exist for that reason alone.
Minimum purity guarantee across all catalog compounds. Many exceed 99%. Purity data included on every CoA.
All peptides are supplied in lyophilized powder form for maximum stability and shelf life under proper storage conditions.
Certificate of Analysis for every batch — including HPLC chromatogram, MS spectrum, amino acid sequence, and lot number.
Endotoxin and sterility testing available upon request for compounds intended for cell culture or in vivo research models.
Starktides works with verified research institutions, qualified laboratories, and authorized scientific personnel. Submit your inquiry and our team will respond within 1–2 business days.
Starktides exists to make peptide research accessible. We believe progress should not be limited by high costs or hard-to-find suppliers. Our goal is to provide trusted research-grade peptides at fair pricing — with the documentation and transparency that serious research demands.
We are committed to improving every step of the way.
