I will add rFSH to my TRT protocol in an effort to regain fertility. I usually travel for business and take my HCG using a FRIO bag that keeps it cool (but not cold) and it works just fine. It seems HCG doesn't lose its potency (based on how i feel and sperm analysis). My question is: is FSH stable at room temperature for 24 hours. Or use FRIO bag that only keeps it cool it cause the FSH to lose potency? Maybe someone from empower pharmacy can shed some light. I know i can use those insulin bags that uses ice packs but those are a hassle to go through security and also dont keep the medice cold for long
