    I get my testosterone cypionate from a compounding pharmacy. It always has an expiration date that is just 2 or 3 months from when I bought it. I have read that testosterone from a pharmicutical company has a much longer shelf life. I never use the full amount of my perscription so end up with extra testosterone. I would like to save some up for a rainy day but whats the deal with the shelf life? Shouldnt it be the same chemical and therefore have the same shelf life as the "name brand" big pharma stuff?

    also, whats the best way to store long term, freeze it?
    thanks

    The reason for shorter dating is due to both the criteria we are told to use for use by dating for compounds and liability reasons. Sterility is the main issue, not drug stability. I would not want to compound an injectable product and take the chance of someone using a partial bottle and contaminating it then using it again a year later. Lawsuits are no fun.

    What about working on one vial to the end.
    Place any unused refills (unopened) in cold storage or a freezer?
    How long would they last, what is the best way to store them?
    Any law suits after the expitation date are easy for pharmacist to handle.
    Real, practical, question, is the testosterone useable?
    Just good wild semi-educated guess??

    Same question for my unopened androgel 5gram sashets.
    I am left with about yearly supply.
    Do not want to thow it out for same reasons.

    That is not a fair question to be asking a professional who is concerned about liability exposure.

    Obviously I won't say "go for it", but in a general sense most NON-sterile products (like androgel) are proven to be stable and effective for quite some time after their expiration. The federal government has done tests on their stockpile for years to prove this. Sterile products are a different story. But, most compounding pharmacists use the same or similar preservatives that the manufacturers do, so I guess use your own judgement at your own risk. As I have said before though, I would definetly not use a large vial (20 or 30 ml) for a long period of time. More small vials would be much safer in terms of maintaining sterility.

    Yes, we discussed this before.
    That 30ml vial, that is available from compounding pharmacy, would last too long.
    With so many needle penetrations it would loose its seal,
    specially with guys insisting on using large needles.

    30ml * 200mg/ml=6000mg

    150mg/week E2D schedule

    6000/150*7/2=140 penetrations

    Any thoughts on how many penetrations of the vial top would be appropriate for the average large needle? (I use a 25 gauge)

    My main concern is how long you use a vial after the first puncture and then how many times you puncture the vial total. I just don't like the idea of still injecting out of a vial I first used 6 months ago. There is no perfect answer, but I wouldn't want to use even a preserved injection for more than 2, maybe 3 months out of the same vial if I were injecting 3 times a week as many now do. Several guys have talked about having 20 or 30ml vials, that just presents too many chances to contaminate the vial and too long to expect the stopper and preservative to maintain integrity.

    Some purposely don't use a preservative.

    Very true. In that case they should be packaged in single dose vials.
