Hello everyone. I am super new to the peptide/steroid world. I has gastric bypass August 2022 and lost 90 pounds. I am currently on ozempic and looking to switch to sema peptides as insurance is shitty. Does anyone have any recommendations on refill injector pens. I saw a forum but would love someone to explain to me like I am 2 on what to buy and how to use it. Thank you so much in advance and I am excited to learn more.
