Common Questions
What is a peptide stack?
A peptide stack is a combination of two or more research peptides selected for their complementary or synergistic mechanisms — for example, combining BPC-157 (local repair) with TB-500 (systemic remodelling) for broader tissue regeneration coverage.
How do I choose a research stack?
Stack selection depends on the primary research focus, compound familiarity, and protocol complexity. The Stack Builder filters by goal and experience level to return the most appropriate combination for your protocol design.
Can I combine compounds from different sub-lines?
Yes — many effective research stacks intentionally cross sub-lines. For example, BPC-157 (SOMA) paired with KPV (REGENERIS) creates a complementary repair + anti-inflammatory protocol. Every recommended stack in the builder accounts for these cross-line synergies.
For research use only — what does that mean?
All Rainbow Peptide compounds are sold strictly for in vitro and laboratory research purposes. They are not approved for human consumption, are not medicines, and are not intended to diagnose, treat, cure, or prevent any disease or condition. Must be 18+ to purchase.
