I was on Viagra and other medications for several years. At first they worked great than they didnt.
Last 7 months I inject Trimix. Boy, do I love the results. Never fails and I have a rock hard erection for 2 hours. Since I use a low dose its cheaper than the medications also. No side effects and Ive noticed my penis is more sensitive and I have stronger orgasms than before. SO you may want to switch. Also wife says it feel thicker. LOL who knows. At least she says it doesnt feel smaller. LOL
