GLPs do not mix well with other compounds and can turn into a thick gel that is hard to push through a fine needle. There is a chart that shows which peptides can be combined in one container. Glutathione probably needs its own syringe as well. The best approach may be to check the best time of day for each compound and look for any overlapping benefits.
I ordered KPV, Selank, DSIP and Glutathione while already using tirzepatide. My schedule calls for five shots a day, which feels like too many. I plan to pull KPV, Selank and DSIP into one syringe, keep Glutathione separate because of the volume, and leave tirzepatide by itself since it should never be mixed with anything else. Any thoughts on that plan? Do the starting doses seem reasonable? Figuring out the right amounts has been difficult.
