Vitamin E, ascorbate, glutathione disulfide, and enzymes of glutathione metabolism in cultures of chick astrocytes and neurons: Evidence that astrocytes play an important role in antioxidant processes in the brain
Table 1 Transgenic plants developed using glutathione S-transferase
The cells were grown to a confluence of 8090% after which the cells were either sub-cultured after trypsinization with 0.05% Trypsin-EDTA (GIBCO, #25300-062) or plated into specific cell densities for treatments
For GHK-Cu, bacteriostatic water (sterile water with 0.9% benzyl alcohol) is generally preferred for reconstitution if storing for more than immediate use, as the benzyl alcohol helps inhibit bacterial growth

When to use IM injection Intramuscular is better when: Treating deep muscle injuries Want faster absorption Prefer muscle over fat injection Targeting specific muscle groups Most people use SubQ: SubQ is easier and works well IM not necessary for most BPC-157 uses IM more painful typically IM injection sites Best muscles: Glutes (butt, upper outer quadrant) Thighs (vastus lateralis - outer mid-thigh) Deltoids (shoulder muscle - advanced) Site selection: Choose muscle near injury if targeting specific area Rotate between muscles Requires longer needle than SubQ IM injection technique Different from SubQ: Longer needle (1-1.5 inch) 90-degree angle (straight in) Into muscle, not just under skin Inject slowly May feel more discomfort Not necessary for most BPC-157 users: SubQ works great
