250 iu a day for what? Different reasons will require different doses. I also don't see many ppl using hcg daily. 3-4x week usually. For pct purpose I use to run 1000iu EOD
On cycles I use to do 250eod but then one day I ran a full blown cycle without hcg and I realized that my nuts dont shrink on cycle, I'm going on 3 years of trt with approximately 2 cycles per year, no hcg, no shrinking beans and no problems.
Kinda irrelevant I guess, my point tho is the reason your using it may dictate the dose you need
