GHK-Cu has been shown in research settings to modulate gene expression related to collagen synthesis, inflammation regulation, and tissue remodeling, making it a focal point in studies involving dermal and connective tissue models
More recently, red-emissive CQDs synthesised from Echinophora tenuifolia were shown to selectively stain non-viable cells with high fluorescent intensity and photostability, a property attributed to their negatively charged surface favouring interactions with compromised cellular membranes, sparing viable cells [98]
Some benefit from weekly injections, while others maintain results with monthly treatments
Vitamin B12 has a good safety profile, but some important considerations include rare hypersensitivity reactions (including anaphylaxis) with injections, potential hypokalaemia during early treatment of severe deficiency, and possible cutaneous reactions
The KYC requirements which can include identity verification beyond what other vendors require create friction that many researchers prefer to avoid
