Selank + Semax liquid spray

What is it for?

Selank and Semax together in one 10 mL atomiser, each at 0.5 mg/mL — 5 mg of each across the bottle, a nominal 50 micrograms of each per actuation. Both carry the same proline-glycine-proline stabilising tail, which is why they can share a solution without one degrading ahead of the other. Purity is reported per component on the certificate. Refrigerate and protect from light.

• What a blend certificate shows, and what it leaves outA single purity figure across two compounds conflates two questions and answers neither. What a multi-component certificate has to report, and the one number people forget to check.
• Why Selank and Semax can share a bottleCo-formulating two peptides only works if neither destabilises the other. These two share a design feature that makes them unusually compatible — and the reasons are specific enough to be worth checking against any blend.
• Cysteine, disulfide bonds and why some peptides need foldingA peptide with two cysteines can form the right bond, the wrong one, or link to a neighbour. This post covers what disulfide bonds do, why the folding step is separate from synthesis, and what cysteine means for handling a vial.
• Aggregation: the failure a certificate will never show youAggregation changes no mass and no purity figure, so no certificate can catch it. This post covers what drives peptides to associate, which sequences are most at risk, how to spot it, and the handling habits that prevent it.
