There is no “compatible” rating here, and there never will be.
Establishing compatibility means particulate counts, pH, potency assay and
degradation products measured over the hold time. Nobody has run that on research
peptides. So the best rating available is “no conflict found”, and the default
answer is two syringes — which costs you nothing.
A blend existing is not evidence. Most blends ship freeze-dried, and dry powder cannot react. Two peptides that would wreck each other in solution sit in one vial looking perfect for years; the reaction happens after you add bacteriostatic water. And the only failure you can see is cloudiness — potency loss is invisible.

What the chemistry says
Where these numbers come from
Isoelectric point and free thiol count are computed from the amino acid sequence. Sequences marked verified were checked against their parent protein in UniProt, or against their published molecular formula in PubChem — a formula match confirms the sequence and both terminal modifications at once. Sequences marked unverified have not been confirmed against an external source and should not be relied on.
A computed pI describes the free peptide in water. The pH of a real vial depends on the vendor's buffer, which varies between vendors for the same compound and is usually unpublished. So pI tells you where precipitation risk sits — not that a given pair will fail.
