Shelf life of oils?

[JK1]

Many variables but let's hear about the shelf life of oils. Not pharma oils.

Let's say they are kept upright. Room temperature and in in a dark place.

Thanks!

You really can just search for that and find a ton of info here already and plenty out on the interwebs.

As per title.
Pure oils, no AAS etc.

MCT / Castor / Mig / whatever

How do you guys store it?
Original plastic container?
Amber sterile vials?
Media bottles?

How long do you store it for?
5 years? 10? 3?
Until the color changes?
Until it smells weird?
Until it finishes?

I recently filtered some of my oils into amber glass bottles, but given how cheap they are, I could just dump it every 2 years and buy small bottles..

Please share.

Depends on the oil the storage time changes a lot. All high unsaturated fats degrade fast and polyunsaturated fats oils degrade even...

Using Q10 factor of 2** (reaction rate doubles for every 10 deg C), then going from 22 deg C (room temp) to 2 deg C (fridge temp) reduces degradation rate by factor of 4.

** only strictly accurate for activation energy = 50 kJ/mol. Rough math.

In reality tho, people have injected oils that are alot older and have survived.
You also don't know the state of the oil being used.
Food grade cheap china oil will not have same shelf life as Pharma grade MCT. The brewer might even be using oil thats 3-4 years old for the brew.

I have some Alpha Pharma ampules with exp. XX.21. Made in XX.17. They work just fine. No pip or problems and bloodwork look like it should.

I’m dare to say, that BA makes them safe for 10 maybe 20 years. API loss is in the one digits %.

But it’s just anecdotal and feelz

Do the ampules even have b.a?
Most amps are for single use (hence no b.a)

When I started my TRT journey (where T pretty quickly also stood for tren, among other very efficacious compounds) 4y ago, I injected what was probably 8-9y old pharma test from 1ml glass amps. Could not tell you what brand it was, because the print had rubbed off.
Still worked like a charm.

Fair point. I did search for it though and did look it up. Maybe should have been more specific. Thanks for your input.

Thanks this is interesting.

Wonder how many people are opting for household fridge storage of their oils vs dark cool room temp (say 18-20 deg celc).

What do you do?

And why stop there. Freezer if +8 years to use? Put i fridge a week. Reheat i crashed.

Everyone has a different tolerance level.

Would you cook and eat fried chicken with oil stored in the fridge sealed in a glass bottle for 10 years? Or freezer for 10 years?

Im personally just after keeping oils in the best condition for like up to 2 years as I use them up. If the fridge is better than a box based on people who know more than me then its an easy thing to do?

So long as there isn't any other downsides that we aren't thinking of. Crashing seems easily resolved.
