Frequently Asked Questions
How many peptides can I compare at once?
You can compare up to four peptides simultaneously. Add compounds from the peptide directory by clicking the "+ Compare" button on any card.
Where does the comparison data come from?
All data is sourced from peer-reviewed literature, PubMed research papers, and clinical study summaries. Each peptide profile links directly to cited research papers.
What is half-life and why does it matter for comparison?
Half-life is the time it takes for a peptide's plasma concentration to decrease by 50%. Compounds with shorter half-lives (e.g. native GHRH at ~7 minutes) require more frequent dosing than analogues with extended half-lives (e.g. CJC-1295 DAC at 6-8 days).
Can I compare peptides from different categories?
Yes: you can compare any combination of peptides regardless of category. Comparing across categories (e.g. a GHS like Ipamorelin against a healing peptide like BPC-157) can help you understand how different compound classes serve different research goals.
