I am midway through current cycle and need Hcg to work on the boys. I have box's that contain 4 pairs of 2500iu ampules. I have a problem due to my current location. I have no fridge to store after opening the amps. Can I get by by using 500iu/day and leaving mix'd hcg unfridgerated for 3-4 days? Can I inject 2500/every 4 days? Also, I injected a large dose sub-q, and the inject site is very tender. The box's say IM. Thoughts?
