Question 1

Are research peptides legal to buy?

Accepted Answer

Research peptides are legal to purchase for research purposes only in most countries. They are NOT approved by the FDA for human consumption or medical use. Always check your local laws and regulations before purchasing.

Question 2

What is Janoshik testing?

Accepted Answer

Janoshik Analytical is an independent laboratory that provides third-party testing for peptides. They test for purity, concentration, and contamination. A Janoshik COA (Certificate of Analysis) is considered the gold standard for peptide verification.

Question 3

How should I store peptides?

Accepted Answer

Lyophilized (freeze-dried) peptides should be stored in a freezer at -20°C or colder. Once reconstituted, most peptides should be refrigerated at 2-8°C and used within 30 days.

Question 4

What purity level should I look for?

Accepted Answer

Look for peptides with at least 98% purity. Reputable suppliers consistently achieve 98-99%+ purity. Any supplier offering peptides below 95% purity should be avoided.

Question 5

How much do peptides typically cost?

Accepted Answer

Prices vary by peptide and supplier. Common peptides like BPC-157 range from $25-40 for 5mg, while more expensive peptides like Semaglutide can be $80-100 for 5mg.

Question 6

What's the difference between domestic and international suppliers?

Accepted Answer

Domestic suppliers typically offer faster shipping (2-5 days) and fewer customs issues, but may have higher prices. International suppliers often have lower prices but longer shipping times (2-4 weeks) and potential customs delays.

Question 7

How do I reconstitute peptides?

Accepted Answer

Most peptides are reconstituted with bacteriostatic water (BAC water). Clean vial tops with alcohol, draw BAC water into syringe, slowly inject into peptide vial along the side, then gently swirl without shaking.

Question 8

What are COAs and why do they matter?

Accepted Answer

COAs (Certificates of Analysis) are lab test results that verify a peptide's purity, concentration, and safety. They should include batch number, test date, purity percentage, and lab information.

Question 9

Can I trust peptide suppliers without third-party testing?

Accepted Answer

No. Third-party testing is essential. Suppliers who don't provide legitimate third-party COAs cannot verify their products' quality or safety.

Question 10

How long does shipping typically take?

Accepted Answer

Domestic US suppliers: 2-5 business days. International suppliers: 2-4 weeks. Factors affecting shipping include location, customs processing, and shipping method chosen.

Question 11

What's the shelf life of peptides?

Accepted Answer

Lyophilized peptides stored properly (-20°C or colder) typically last 2-3 years. Reconstituted peptides last 30-60 days when refrigerated.

Question 12

Do I need a prescription to buy research peptides?

Accepted Answer

No prescription is needed for research peptides as they are sold for research purposes only. However, they are NOT intended for human consumption.

Question 13

What are the most popular peptides?

Accepted Answer

The most commonly researched peptides include BPC-157 (healing/recovery), TB-500 (tissue repair), Semaglutide and Tirzepatide (weight management), GHK-Cu (anti-aging), and PT-141 (sexual health).

Question 14

How do I know if a supplier is legitimate?

Accepted Answer

Check for: third-party testing with verifiable COAs, transparent contact information, professional website, consistent positive reviews, clear product information, and responsive customer service.
