Leave it in for the whole vial. If you change it every time it would destroy…

Just as long as it doesn’t get condensation

my man im 3 years into medical school bac water after being opened should be stored in the fridge

Yeah

how's shipping to the US? I read reviews but they don't really specify were they are at.

Mine was going for 6 months 🤣

I'd say 2/3 weeks

I keep mine in the fridge and no issues

Everywhere really

Some people will die on this hill on either side lol

No — you should not refrigerate testosterone vials. Here’s why: Oil-based solution: Testosterone injections (like cypionate, enanthate, or decanoate) are suspended in oil, not water. Cold temperatures make the oil thicker and cloudy, which can make it hard to draw and inject. Proper storage: Keep testosterone at room temperature (68–77°F / 20–25°C) and away from direct sunlight or heat. Do not freeze: Freezing can cause the hormone to precipitate or separate from the oil, which ruins the product. ✅ Summary: Store at room temp. Keep sealed and out of light. Don’t refrigerate or freeze.

read what i replied to

Mine in my draw 🤣🤣

What you been pinning.

i always do and heat up the syringe gets rid of like 90 percent of pip

If you keep bac in fridge do it, if not then it's not an issue.

How do you all get pip for test? Subq is the only way it gives me pip but im I'm sound

3cc at a time

higher concentrate too crystalizes in the muscle tissue

Ah that's fair yea I only do small amounts like 0.3ml 🤣

thats why i love cutting a break from all the oil up my ass
