@Melissa - Hi Melissa! 🌸💕 I have been out of the loop for a while and am just getting back on the bandwagon again for some self-care. I am new to peptides and multiple other new products, so please bear with me while I ask questions. This is my second of the day, and here it goes. Is this product for sale a peptide for injection, or is it used for microneedling, etc.?
