Peptide Stack Builder
Combining multiple peptides in a "stack" is common in research to target multiple pathways simultaneously. This tool helps you design a stack based on your research goals while flagging potential interactions.
The Peptide Stack Builder is an interactive tool that helps researchers design multi-peptide protocols based on specific research objectives. Select your primary goal (healing, body composition, anti-aging, cognitive enhancement, or general wellness), and the builder suggests evidence-based combinations with synergistic potential. For each stack, the tool provides dosing guidelines, optimal timing for each compound, injection scheduling to minimize the number of daily injections, and flags any known or theoretical interactions between compounds. It also estimates the total daily injection volume and monthly cost for budget planning.
How to Use
Select your primary research objective from the available categories.
Review the suggested base peptide for your goal, or choose your own from the full list.
Add complementary peptides from the suggested options, reviewing synergy notes for each.
The builder generates a complete daily schedule showing dose amounts, timing, and injection details for each peptide.
Review the interaction checker panel for any warnings or contraindications between your selected peptides.
Export your complete stack protocol as a printable reference card.
Formula
Stack Synergy Score = Sum of individual efficacy ratings + interaction bonuses - interaction penalties. Higher scores indicate more theoretically synergistic combinations.Example
A healing-focused stack might combine BPC-157 (250mcg twice daily) with TB-500 (2mg twice weekly). The builder would schedule BPC-157 in the morning and evening, TB-500 on Monday and Thursday mornings, note the complementary mechanisms (BPC-157 for angiogenesis and TB-500 for cell migration), and estimate a monthly cost based on current average pricing.
Frequently Asked Questions
Is it safe to combine multiple peptides?
There is limited clinical data on peptide combinations since most studies examine individual compounds. Combining peptides that act on similar pathways could theoretically cause excessive stimulation, while combinations targeting complementary pathways may be synergistic. Always start with one peptide at a time to assess individual response before adding additional compounds to a stack.
Can I mix different peptides in the same syringe?
While some researchers combine compatible peptides in a single syringe for convenience, this is generally not recommended unless the specific combination has been verified as stable. Mixing peptides can potentially cause degradation, precipitation, or altered absorption profiles. Separate injections, though less convenient, ensure each peptide is administered at its intended concentration and stability.
How long should I run a peptide stack?
Stack duration depends on the specific peptides and research goals. Healing stacks (BPC-157 and TB-500) are typically run for 4-8 weeks. Growth hormone secretagogue stacks (Ipamorelin and CJC-1295) are often run for 8-12 weeks with breaks. GLP-1 agonist protocols may run longer. The builder provides recommended durations for each stack combination.
