possible vial contamination?

I have a vial of test cypionatethat i've had for around a year it seems to have some small white clear looking particals floating in it could this be the test coming out of the solution and crystalizing from sitting for so long?

Yes. If the vial is still sealed and you are 100% sure nothing could have entered the vial then the substance is most likely cyp powder.

I recommend heating the vial and shaking it and it should be reabsorbed. To heat it, get some hot water from the sink (or heat it up on the stove) and place the vial in the water. Do not submerge the entire vial, leave the top portion of it above the water. Let it sit for about 10 minutes and you should be fine.

An alternative is to heat it in the stove. Heat the stove to around 200 degrees, prior to placing the vial in the stove, place a needle in the top of the vial to let air get out, then heat for 10-15 minutes.

I prefer heating my vials in water. The reason being is that the oven will heat the rubber stopper and it can become brittle which can lead to rubber breaking off into the vial when you use it for injecting.

Every time I do a homebrew batch I always get a little rubber in the vial and it is one of my pet peeves so I always try to do things to avoid that from happening.

I have a Whatman filter. How many milliliters can I run through it before it no longer works properly?
