When would you choose Aura vs Glow vs Klow?

The three tissue-repair blends differ by which combinations of layers they address. Aura (GHK-Cu + BPC-157 + KPV) covers gene expression, vascular supply, and inflammation control. It is the best choice when chronic inflammation is a rate-limiting factor for the repair goal and cellular migration is not the primary need.

Glow (GHK-Cu + BPC-157 + TB-500) covers gene expression, vascular supply, and cellular migration. It is the best choice for cosmetic-dermal repair and skin rejuvenation contexts where the primary need is structural remodelling with adequate cell delivery to the site — inflammation control is less prominent because the target is not typically inflamed tissue.

Klow (GHK-Cu + BPC-157 + TB-500 + KPV) covers all four layers. It is the most comprehensive choice and appropriate when all four mechanisms are needed simultaneously — typically in more complex or chronic tissue-repair contexts where multiple limiting factors are simultaneously present.

Individual peptides give more dose flexibility than any blend because the ratios of a blend are fixed by the manufacturer. If your protocol wants to titrate one component up or down independently of the others, individual peptides are preferable. If the fixed-ratio blend proportions match the protocol you want, the blend format is simpler than reconstituting and injecting multiple separate vials.
