Dianabol (Methandrostenolone) Shelf Life - Anyone?
I've searched, used every advanced searching method I know, and searched some more and I can't find the answer from a technical standpoint on the Forum.
Does anyone know how long Dbol will last if kept airtight, temperature and humidity controlled, light-free and with a desiccant? It's my understanding that most pharmaceuticals don't go "bad" but their efficacy reduces with age and that rate is dependent on storage conditions.
Would Dbol stored as described above be 90% effective after five years? 50% effective? Are there any studies on this that anyone is aware of? Heck, would it last indefinitely?

I can't back this up by studies on DBOL specifically,
but the reason Pharma drugs have a 5 year exp date isn't because they only last that long, but because of some legal issues.
And studies done on more "sensitive" drugs like insulin showed that there was no reduction in potency 2 years after exp date if kept according to guidelines. (In the fridge for insulin) The study I'm referring to was done by the US army as medicines past exp date is a huge cost.
My guess is that DBOL should last at least 10 years over exp date if kept in dry, room temp environment.
I don't think there will be ANY decrease in potency actually.
But this is my speculation only.
This would not apply to liquid preparations from UGL labs like liquid arimidex , etc, as water is involved in the degrading process. So is sunlight.
