Due to moving and temporarily having no access to my own freezer, I kept the unmixed vials out of the freezer and fridge for two months.
I know the effects very well. When frozen and keeping the mixed vial in the fridge, my arm hair and pubic hair start darkening at 1 mg a day, head hair darkens at lower doses.
When I use those amounts now, my head hair is still darker, but other parts don't get as dark as having used them on the same amounts before.
I thought M2 in unmixed form could survive for a long time, but it seems to work just not as potent. Is this normal or has the seller kept it out of the freezer as well so I added the extra months to make it less potent.
