Common questions

Is the CJC + IPA Stack one vial or separate vials?+
It’s a stack — 2 separate, individually sealed vials (CJC-1295 (No DAC), Ipamorelin), not a single combined blend vial. Each ships full-size with its own lot-matched COA.
What’s the difference between a stack and a blend?+
A blend combines every peptide into one vial at a fixed ratio. A stack keeps each peptide in its own vial, so you can reconstitute, dose and store each one independently in vitro.
Does each vial come with a COA?+
Yes — every vial in the stack ships with its own lot-specific Certificate of Analysis covering HPLC purity, LC-MS identity, net content, heavy metals, sterility and endotoxin, matched to the lot ID on that vial.
How do I reconstitute the CJC + IPA Stack?+
Reconstitute each vial separately in sterile bacteriostatic water. Because the peptides are in separate vials, you control the concentration of each independently. Store reconstituted solution at 2–8 °C.
How should the CJC + IPA Stack be stored?+
Hold each lyophilized vial at −20 °C, sealed and away from light. After reconstitution, store at 2–8 °C and avoid freeze-thaw cycles.
What is the CJC + IPA Stack supplied for?+
Koi stacks are research-grade material supplied exclusively to qualified researchers and laboratories for in-vitro study. Each vial is lyophilized in the USA and independently third-party verified.
