TriMix expiration date?

Postby radioradio » Thu Apr 20, 2017 6:59 pm

My first TriMix Rx was filled on 4/7/17 and the label says it expires on 6/6/17. I can't get in to my uro to get my "learn how to stick your dick" lesson until 5/18/17.
So, I'm looking for some input about how long this vial is really okay to use. My uro's PA told me one vial would be good for about 60 injections. I asked her if she expected me to have 60 erections in 3 weeks. She said that would be impressive and we had a good laugh.

Seems like a waste of meds, money and erections to dispose of it after 3 weeks.

Any input would be appreciated.

65 y.o. Married 38 years. Robotic RP 3/1/17. ED 50+% of the time prior to surgery, with meds. Started pumping 4/1/17. Starting trimix injections 5/15/17. Was considering implant even before PCa diagnosis, and now even more.

If you keep it frozen, It'll last as long as you will.
Just defrost it to fill a couple syringes and keep them either frozen or refrigerated.

In the freezer it will probably last you a a year.
What is your formula?
Seriously consider buying a Autoject El. Makes injections much more predictable and painless. I went through a lot of frustration, but this $40 gadget changed everything .
With the Doctor go with small dose. Mine gave me 25 units and now even 3 is too much.
Practice by yourself without the pressure of performing sex. This way after about half a dozen time you should get it.
Go gradual, ask questions here.
All the best!

I keep mine frozen and it lasts a year...easy. I freeze vial and thaw for each injection. Takes 10 minuets to thaw.

I had that same question regarding expiration dates. I took this question to my urologist.

Q: Will it still work after the exp. date?
A: Probably yes
Q: Regardless if it works or not, is there any danger injecting expired trimix?
A: NO, but you may need to adjust units injected

My Trimix expired more that 8 months ago, and it still works fine with regular dose.

I do keep mine in the refrigerator
