Guaranteed erection, but are side effects worth it?
As a 62-year-old man, my libido has been declining in recent years, and most common aphrodisiacs aren’t working like they used to. I stumbled on Zyrexin at a drug store 3 or 4 years ago and took 2 tablets before going to a strip club. Within 45 minutes I began getting hard, and when sexually stimulated either visually or with close female contact; the result was great! At those first few uses, I never noticed the chills and shaking effect; because I was fully dressed and moving around a little. 2 years ago, I began taking 1 or 2 pills as directed prior to my massages; so as not to embarrass myself when naked with a little flaccid penis. However, while undergoing the massage, which always felt great; I began to get chills and began experiencing muscle shaking and quivering to the point that the therapist would notice and have to apply thermal pressure to the affected areas and a heating pad to relax the muscles. I had isolated this down to the Yohimbine extract after years of experimenting with herbs and their effects. Yohimbe is fantastic for an NO boost to the genitals; but general ‘yukky’ feeling and a feeling of rapid heartbeat, anxiety, and chills are the biggest downsides. So if I take it at all, I take 1 capsule with only 8 mg of Yohimbine, and I still have a decent erection with moderated side effects. I would take 2 in the summer months or when I’m warmly dressed in the winter, but God, I wish I had my 25-year-old ‘Woody’ back without having to take any pills!
Zyrexin side effects
I have too many side effects from this. I sweat, heart rate increases, anxiety, and cannot sleep after taking the Zyrexin pill.
Did Nothing for me
These pills have done nothing for me. I’ve tried with changing qunatities of the pils as well as I have chnaged tried taking these pills at different times but they had no effect.
