One reason for this difference is that there are different kinds of B12 injections, each working for a long time
This cAMP elevation activates protein kinase A (PKA), which phosphorylates transcription factors including CREB, ultimately increasing GH gene transcription and protein synthesis
Since ingredients like retinoids and high-dose salicylic acid are off limits [due to the potential to cause developmental defects], she recommends looking for gentler exfoliating acids like lactic, glycolic, and azelaic acids, as well as sulfur-based acne spot treatments as alternatives to help prevent and treat breakouts
An important caveat: the effect required a multi-month increase in muscle carnitine concentrations, not a single serving which underscores why a fully bioavailable form and a consistent protocol matter
