I'm using bimix, 0.2cc, but I don't think you can make direct comparisons. Different bodies need different doses and there are differing formulas in use too. So it is a matter of experimenting to find the right technique and dosage for you.

I find an essential part of the procedure is to apply some constriction to the base of the penis as you do the injection and for about three minutes after. I use a few office rubber bands doubled over. And of course plenty of massage to spread the injection around.

If that does not improve matters, try increasing the dose, a little at a time.
Age 63 at diagnosis, now 64.
No symptoms; PSA 5.7; Gleason 4+5=9; cancer in 4 of 12 cores.
Non-nerve sparing RRP on 7 March 2008.
Two nights in hospital; catheter out after 7 days.
Continent; no pads needed from the get-go.
Pathology showed organ confined and negative margins. Gleason downgraded to 4+4=8.
6-week : <0.05
7-month: <0.05
13-month: 0.07 (start of a trend?)
After a learning curve, Bimix injections (0.2ml) are working well. VED also works but we find it inferior to Bimix.

I also use .2 trimix injection at it seems to work. For me, it takes about 15-20 minutes before I get the erection. I also do a lot of rubbing and stimulation. I haven't tried the rubber band but I'll give a try.

Here's some of my saved items dealing with the subject, in no particular order. In particular, look for the posts detailing the plumping techniques that some of have developed to help insure proper adsorption of the drugs into the penile tissues. If you are getting an erection with trimix, then losing it quickly, it may take the plumping and restriction for a few minutes to ensure that the drug is adsorbed before using. That's what Piano, myself and several others are talking about and using. We hold the drug in the penis, using a penis ring or band, to allow for good adsorption, ensuring a better chance of success, and the use of less drug to acheive the same effect. Ask further questions, someone will have the answer, I hope....

I stand after I inject because that seems to make the drugs work faster. And if I lay down, I do lose part of the erection but if I stand back up and walk around, it comes back. It all seems to be related to blood flow. When you are standing, the blood gets to your responsive areas easier. quicker, etc.

Just recently, I found that the closer you are to the expiration date of the Trimix, the less effect you will obtain. It definitely doesn't seem to last over 90 days.
