How to Use This Library
Navigate by Category
Use the category filter above to narrow results. Each category groups peptides by their primary mechanism or use case. Some peptides appear in multiple categories if they have diverse applications.
Understanding Dosing Ranges
Each peptide card shows three doses: starting (for first-time users), therapeutic (standard protocol), and maximum (upper limit from literature). Always begin at starting dose regardless of experience to assess individual response.
Cycle Lengths
Cycle duration depends on the peptide class. GLP-1 agonists are typically continuous therapy. Healing peptides run 4-8 week cycles. GH secretagogues often follow 5 days on / 2 days off. Check individual peptide pages for specific protocols.
Stack Suggestions
Each peptide page includes synergy notes showing which other peptides complement it. Not all peptides stack well—some share pathways and combining them adds risk without benefit. When in doubt, use one peptide at a time.
Frequently Asked Questions
What is the most popular research peptide?
BPC-157 is currently the most popular research peptide due to its broad applications in injury recovery and gut healing. For weight loss, semaglutide dominates searches. For cognitive enhancement, semax and selank are most discussed. Popularity varies by community—bodybuilders favor growth hormone secretagogues, while longevity researchers focus on mitochondrial peptides like SS-31.
Which peptides are best for injury recovery?
BPC-157 and TB-500 are the primary healing peptides. BPC-157 excels at tendon, ligament, and gut repair with dosing typically at 250-500mcg daily. TB-500 promotes systemic tissue repair and is often dosed at 2-5mg twice weekly during loading, then weekly for maintenance. Many stack both for synergistic effects.
What is the difference between peptides and steroids?
Peptides are chains of amino acids that signal the body to perform specific functions—they work with natural pathways. Steroids are synthetic hormones that directly override natural hormone levels. Peptides generally have fewer side effects and do not cause hormonal shutdown. However, peptides work more subtly and often require longer timeframes to see results.
Are research peptides safe?
Safety varies by peptide. GLP-1 agonists like semaglutide have extensive clinical trial data establishing their safety profile. Others like BPC-157 have limited human data but decades of animal studies and community experience. The biggest safety variable is source quality—only purchase from verified vendors with third-party testing. Start with low doses and titrate up.
How do I choose the right peptide?
Start with your goal: weight loss (GLP-1 agonists), injury recovery (BPC-157, TB-500), cognitive enhancement (semax, selank), body composition (CJC-1295/Ipamorelin), or longevity (SS-31, MOTS-c). Then research the specific peptide—dosing protocols, expected timeline, and potential side effects. Begin with one peptide to assess individual response before stacking.
Can peptides be stacked together?
Yes, many peptides are commonly stacked. Popular stacks include: BPC-157 + TB-500 for injury recovery, CJC-1295 + Ipamorelin for GH release (synergistic effect), semaglutide + tesamorelin for weight loss with muscle preservation. Avoid stacking peptides that affect the same pathway without understanding interactions. Start compounds separately, then combine once you know your individual response to each.
