The habit that solves this is writing the puncture date directly on the vial the first time you enter it
Injection frequency also varies by peptide: some protocols are daily, while others such as BPC-157 use a 5-days-on, 2-days-off structure
The millimolar GSH intracellular concentrations, the low plasma micromolar concentrations and the low GSH redox potential ( E 0 = 240 mV) make GSH an ideal and perfect cellular redox buffer (Figure 2) ( FIGURE 1 FIGURE 2 Glutathione is synthesized in the cytosol of all cells from their precursor amino acids: glutamic acid, cysteine and glycine by consecutive action of two enzymes: -glutamyl-cysteine (-GluCys) synthetase (also known as glutamate cysteine ligase, GCL) that in a first step uses glutamate and cysteine as a substrate to form the dipeptide -glutamyl-cysteine
For patients pursuing systemic regenerative or wound-healing protocols, injectables have a legitimate role under physician supervision, but if you are asking about wrinkles, skin firmness, or hair thinning, topical is the right delivery method
