Frequently Asked Questions
What is Selank?+
Selank is a synthetic analog of the immunomodulatory peptide tuftsin, developed at the Institute of Molecular Genetics of the Russian Academy of Sciences. It is associated with research in anxiolytic effects, stress response, and cognitive function. We aggregate pricing data from vetted vendors to help researchers compare true landed costs. This site does not provide medical advice.
How is the price per milligram calculated?+
Price per milligram ($/mg) is calculated by dividing the listed vial price by the total milligrams of peptide in the vial. For example, a 5mg vial priced at $37 has a $/mg of $7.40. This metric allows direct comparison across different vial sizes and vendors.
What does 'estimated landed cost' mean?+
The estimated landed cost includes the base price minus any available code discount, plus the standard shipping fee. It represents the approximate total you would pay to receive the product. Actual costs may vary based on your location and order total.
How often are prices updated?+
Prices are currently checked and updated on a weekly basis. Each offer row shows a "Last Checked" timestamp so you can see how recent the data is. We visually mark data older than 48 hours.
Trust & Verification
How do I verify if a vendor's COA is legitimate?+
Certificates of Analysis should have batch or lot numbers that match your specific order, come from recognized independent laboratories (such as Janoshik or Colmaric Analyticals), and show specific test results including purity percentage and endotoxin levels. Be cautious of generic PDFs that do not reference a specific batch — these may not reflect the actual product you receive.
What trust signals should I look for when choosing a vendor?+
Key trust signals include a published business address, credit card acceptance (which provides chargeback protection), responsive customer service, third-party testing with publicly available COAs, cold-ship options for temperature-sensitive peptides, and positive community mentions across independent forums. Vendors that meet more of these criteria tend to be more reliable.
What does the testing score (X/6) mean?+
Our 6-point testing framework evaluates vendors across six quality dimensions: Net Purity (COA-verified peptide purity), Net Quantity accuracy (actual vs. labeled amount), Endotoxin testing, Sterility testing, Heavy Metals screening, and Conformity assessment. A higher score indicates more comprehensive quality testing. Not all vendors publish results for every category.
Shipping & Storage
Why does cold-chain shipping matter?+
Peptides are sensitive to heat and can degrade if exposed to elevated temperatures during transit. Cold-pack shipping — using insulated packaging with ice packs — costs more but significantly reduces the risk of degradation, especially during summer months or when shipping to warmer climates. Check each vendor's shipping methods before placing an order.
How should peptides be stored after delivery?+
Store peptides at 2–8°C (36–46°F) in a refrigerator, away from direct light. After reconstitution, most vials remain stable for approximately 30 days when kept refrigerated. Unreconstituted lyophilized peptides can last longer when stored properly. If your product arrives warm or with melted ice packs, contact the vendor immediately.
Regulatory
What does 'for research use only' mean?+
This is a standard legal labeling convention for compounds that have not been approved by the FDA for human consumption or therapeutic use. The label is not a statement about the purity, quality, or safety of the product itself. Always verify vendor testing practices and COA credibility independently, regardless of labeling.
