Thanks for the advice! Do i need a cock ring that goes around my penis only or penis and scrotum. Also? What device would. You recommend? I use this at base of penis: https://www.amazon.com/Erecxel-Adjustable-Penile-Bands-Essentials/dp/B00070D37A http://img.takeherbal.com/more1/13/13307.jpg

I average every 10 days and I have had 5 hrs duration from the beginning (7 months so far). I sensed that you were stressing over duration (over 4 hrs)...and I think this issue has been way overblown. I did a lot of *research* and to be honest...the *LINE IN THE SAND* as far as possible damage is cl...

Agree..I use an adjustable ring and apply it just AFTER injecting. I leave it on for as long as 30-60 min...no more.
Make sure it's adjustable so you can easily remove it when you're still *full*.

Not sure what your concern is. If you can get a satisfactory erection sufficient for sex, then what happens after should be of much less *concern*. My erections last 5hrs...and I can't get the duration time down, or it results in less than an initial optimal erection. I have no concerns on the 5 hr ...

This might be a silly qustion but ... If a Trimix erection lasts four hours but the rigidity lasts less than an hour due to the rapid "decomposition" of the PGE1, can a second injection of a few units of PGE1 alone be taken to improve the rigidity but not longetivity? Secondly, if trimix ...

OK, so 5 units gave a so so response. Go right to 15 units (what I use). If that doesn't provide FIRM erection, then keep going UP until it's FIRM. Also depends on strength of trimix used. My erections last 5 hrs..but not painful. I no longer worry about the Erection *TIME* as many others do here......

You can't possibly inject more than 1 ML at a time (100 UNITS)...so you can't inject 1.5/2.0/2.5ML with one syringe !! Sounds like utter confusion here. They were probably referring to UNITS...15/20/25..etc. Again there are 100 UNITS per 1ML Syringe. So the .5 mark on the syringe is 50 units.....ONE...

thanks rahod1. were you ever off target or have a needle break? I use 29 gauge 1/2 inch needles for manual injection. Never *off target*..since you can be fairly precise in placing it. However, ONCE, I failed to get a reaction for some reason..guess it didn't penetrate properly. I immediately re-in...

Need to clarify units vs Ml. There are 100 units in 1 ML. Most doses are in the 20-30 UNIT range! That's .2 to .3 ML
Syringes come in 1 ML that's 100 UNITS! (also come in 30 and 50 units as well. That's .3 and .5 ML syringe)
