How long should a research peptide cycle be?

Typical research cycle lengths vary by compound: BPC-157 is often researched for 4-12 weeks, GH secretagogues for 8-24 weeks, and nootropic peptides for 4-8 weeks. Protocols are detailed in each compound's research guide.

Why take a break between research cycles?

Breaks allow researchers to assess baseline function, monitor for receptor desensitisation, and evaluate lasting effects of the previous cycle independently of ongoing administration.

Should peptide research cycles be continuous or pulsed?

Different compounds suit different administration patterns. GHRH/GHRP combinations are typically pulsed (mimicking natural GH release). BPC-157 can be administered continuously during acute recovery research. Protocol details are compound-specific.
