Costco and cost is $128 Canadian.
250 M W F (used to take every other day) but like it this way....less pinning and do my Test the same way (100/wk with insulin needle quads and delts)
Smaller dose might make sense but I push the 1 month recommended expiry once mixed to 2 months already. Can it last longer without losing too much of its potency? I've read differing opinions on this.
