"Hi Serge, I appreciate that you took the time to respond to my e-mail. Thus far I took 2 days off and tried the Tonkat ali again. The libido boost was dramatic once again. I had intercourse and about a half an hour later I was hard and ready to go again. Later that evening I was fortunate enough to go a third time. I don't remember having that much libido even when I was 18. On day two now I will see what the libido boost effect is like. I can see I will have to fine tune my dosage and schedule for maximum effect. I also noticed the the effect seems to be at its best some 4-6 hours after ingestion and remains in effect for another 8 hours afterwards. This all adds up to less spontaneous sex and more planned encounters. I also noted that because it takes so long for the effect to maximize; I tend to lay awake until 1:00 a.m. with insomnia. Once I fall asleep however I sleep very soundly with few sleep interuptions. I was initally put off by the purchase price of the product. The initail cost of $135 US ($165 Canadian) seemed a little high for an untested product (untested by me). By comparision however I would have to say it will prove to be one of the most cost effect purchases I have made. A 1 gram daily dose along with cycling the dosages can easily translate into 3 months or more of product. The most important factor being that this stuff actually works. A bottle of placebo from the local health food store typically costs $50 and if it works at all the effect is minimal. Your web site was the key to my finding this quality herbal medicine. Thank you for your honest and helpful data. Thanks again for your reply to my questions."
