When does testosteron raw material expire?

[schwarzeneggerarnold]

Does testosterone raw material expire after a certain time, or is it vacuum-packed and properly stored and can it last forever? It would be nice if one could store raw materials for one's TRT for life.

Have people here ever used/brewed Testosteron raw materials that were many years old?
It would be very interesting to know at what point it really loses a significant amount of active ingredient and is no longer usable

if you keep it away from light, moisture, air & excessive temperature changes/high temps, you should be good for 1-2 decades

I have test enanthate raws that are 15 years old. Stocked up on enough to last a lifetime. Vacuum sealed in a good freezer. Still good as the day received.
