The vials in question have been stored in a climate controlled environment with no exposure to light. These were left over from when I stopped. I am now ready to restart and would hate to waste these. Any thoughts on safety?
Thanks In Advance
Don't buy into the 27 date expiration date. The reality is no one tested these vials beyond 27 days and that's where the expiration date comes from.They last 27 days after they have been used. The ones I have were never open. Thanks anyway but I threw them away tonight…
