Frequently Asked Questions
How long is a typical peptide cycle?
Cycle lengths vary by peptide and goal. BPC-157 and TB-500 are commonly run for 6–8 weeks. Growth hormone secretagogues like Ipamorelin and CJC-1295 are often run for 12–16 weeks. GLP-1 peptides are typically used long-term under medical supervision. Always follow published research protocols.
How many vials of BPC-157 do I need?
At a common research dose of 250 mcg twice daily for 8 weeks, you would need approximately 28 mg total. With 5 mg vials, that's 6 vials. Use the calculator above with your specific protocol to get an exact number.
Should I buy extra vials?
It's common to purchase 1–2 extra vials to account for potential loss during reconstitution or priming syringes. Peptide stability also varies — reconstituted peptides typically last 4–6 weeks refrigerated, so plan your purchases accordingly.
How long do reconstituted peptides last?
Most reconstituted peptides remain stable for 4–6 weeks when stored in the refrigerator (2–8°C) and reconstituted with bacteriostatic water. Lyophilized (unreconstituted) peptides can last months to years when stored properly.
