If you don’t already know what RU58841 is, it is a non-steroidal experimental anti-androgen, which is intended for use as a topical treatment for acne and androgenic alopecia (male pattern baldness).

There are a lot of myths surrounding the proper storage of this research chemical, and I’m going to quickly clarify every thing for you in this quick article.
How To Store RU58841 Pre-Mixed Solutions
Essentially, to prevent degradation of the compound, you simply must make sure it's stored out of any direct light and it's in a cold enough temperature.
The only two viable places that your everyday household would have for proper storage conditions of RU58841 are the freezer, or the fridge.
Although RU58841 can remain potent in room temperature for a while, I put my mixed solutions into sealable 50ml bottles, and then put the bottles into a container, shut the container so no light can get in, and then put that in the fridge.
My raw RU powder is always sealed in zip-locks though in the freezer.
I've actually noted as of recent that storing mixed solutions (not RU raw powder) in the fridge is probably more ideal than the freezer for convenience reasons.
Allow me to explain this, as I used to recommend storing all RU58841 (mixed and unmixed) in the freezer.
Although the freezer will ultimately result in the greatest longevity without degradation of the product, it can cause slight crystallization of the RU58841 powder reconstituted in the Ethanol/PG, making it so you may have to let it sit in room temperature and then lightly shake it a bit to make sure it's fully dissolved again prior to each administration.
No crystallization occurs in the fridge though.
It's also still cold enough to offset degradation to a large degree, but not cold enough to cause crystallization of the powder in the solution basically.
This makes the fridge ideal for the storage of mixed solutions.
How To Store RU58841 Raw Powder
As opposed to pre-mixed RU58841 solutions, all RU58841 raw powder (unmixed) should always be kept in the freezer.
I keep those sealed in several ziplock bags, in another closed container to ensure no water somehow seeps in and hits the powder.
If you follow the storage recommendation outlined above in your research, you will maximize the potency and longevity of your RU58841.
