That list works but the needle size is larger than necessary. Try 31g or 32g with 8 mm length instead. Most of the other steps are optional; nothing bad will happen if you skip them. Angling the needle only applies to longer ones. With half-inch or shorter you go straight in. I avoid thighs and like tricep or side delt instead. Hope you meant 1 mg and not 1 ml.
Before buying some Reta I wanted to check that I had all the needed items, along with tips others have mentioned here. Reta before mixing can sit at room temp but a freezer is suggested. After mixing it goes in the fridge and can last over 60 days based on what I've read. Insulin syringes in 30 gauge, 1 ml with half-inch needle are one recommended size. Alcohol wipes for cleaning the tops of the peptide vial and the BAC water. Some suggest a dedicated case for keeping the peptides in the fridge. Let everything reach room temp before injecting. Drip the BAC water down the inside of the vial onto the peptide. Don't push the needle hard. Don't shake once mixed; roll it between your hands and wait until it looks clear. Pinch the skin at the injection spot and go in at an angle.
