HEK293T cells were transfected with 1 g lentiCRISPRv2 containing the sgRNA insert, 0.67 g psPAX2 (Addgene, 12260) and 0.33 g pVSVg (Addgene, 8454) using 6 g polyethylenimine (Sigma-Aldrich, 919012) in Opti-MEM (Thermo Fisher, 31985062)
If the injection is needed (e.g., to replete B or B in a deficient mother), it can be used, but the infant should be observed for any unusual symptoms (though none would be expected from B vitamins, apart from perhaps looser stools if anything)
The biggest difference is how comfortable my skin feels
GHK-Cu needs more large-scale human RCTs before it reaches the evidence threshold of retinoids
Independent laboratory groups have studied the compound across multiple cell types and have observed consistent gene-regulatory patterns in regenerative pathways, while contemporary literature has investigated nanoparticle and hydrogel delivery vehicles and has characterised the compound's pharmacokinetic profile across topical and parenteral routes
