Where to Buy Selank for Laboratory Research
Researchers looking to buy Selank for laboratory use should evaluate suppliers on four things: where the peptide is actually synthesized, purity documentation, endotoxin and identity testing, and shipping/cold-chain handling. PX1 Research supplies Selank that is manufactured, lyophilized and packaged in the USA — no overseas synthesis, no imports.
What to look for in a Selank supplier
Not every seller listing Selank actually synthesizes it. Many resell imported bulk peptide that has been re-vialed domestically. A defensible supplier discloses where synthesis happens, publishes third-party purity and identity data, and provides a batch-specific certificate of analysis (COA) for the exact lot shipping to your bench.
At minimum, ask any Selank supplier for: (1) HPLC purity ≥99%, (2) mass-spec identity confirmation, (3) net peptide content by nitrogen analysis, (4) endotoxin (LAL) screening, and (5) a same-lot COA — not a generic template.
Purity, identity and endotoxin standards for Selank
Every batch is third-party verified by an ISO 17025-accredited lab and ships with a certificate of analysis (COA).
Selank is verified by HPLC-UV for purity, LC-MS or MALDI-TOF for identity, and LAL for endotoxin. Every PX1 batch of Selank ships with a COA documenting these results against a signed batch record. See our published purity and endotoxin reports for representative documentation.
USA-synthesized Selank vs imported
Overseas Selank typically arrives as bulk lyophilized powder that is re-packaged in the U.S. under a distributor's label. That breaks the chain of custody: the reseller can't audit the original synthesis, and lot-to-lot consistency depends on a factory the reseller doesn't operate. PX1's Selank is manufactured, lyophilized and packaged in the USA — no overseas synthesis, no imports — synthesis, testing and vial filling all happen in-house.
Shipping, storage and reship policy
Selank orders placed before the daily cutoff ship the same or next business day from our U.S. facilities via tracked domestic carriers. Cold-chain packaging is used where required. If a shipment is delayed or damaged in transit, PX1 reships at no cost.
Research context for Selank
As a research peptide, Selank is supplied as a research-grade compound for in-vitro and laboratory investigation. All material is sold strictly for laboratory and research use only — not for human or veterinary use, diagnosis or treatment.
Buy Selank at wholesale
Clinics, telehealth platforms and research groups can order Selank at wholesale pricing with custom labeling and branded COAs. Minimum wholesale order is 100 vials per SKU. See the wholesale store for current per-vial pricing.
Frequently Asked Questions
Where is the safest place to buy Selank?
The safest Selank supplier is one that publishes per-lot COA, HPLC purity and endotoxin data and synthesizes in the U.S. under a signed batch record. PX1 Research meets all four criteria.
Is your Selank really made in the USA?
Yes. PX1's Selank is manufactured, lyophilized and packaged in the USA — no overseas synthesis, no imports. We do not import lyophilized bulk and re-label it.
What purity should I expect from Selank?
≥99% HPLC purity, with identity confirmed by mass spectrometry and endotoxin screened by LAL. Every batch ships with the supporting COA.
Can I buy Selank in bulk?
Yes — wholesale Selank is available with custom labeling and branded COAs. Minimum wholesale order is 100 vials per SKU.
