I have been using the blue pills for 10 years.  Recently, I heard some news about the Chinese T-man ED pills but have never tried.   People say if keeps it rock much longer but have a headache side effect.   Anyone has tried this pill?

side-effects that involve headaches, it means it's affecting your brain.  Is that really what you want to do while you're naked?  

Common headaches are due to muscles, nerves and blood vessels around the head, face and neck.  Not really brain related.

Not sure where that remark came from, but  
1.  The brain has no* pain sensors, so headache pain is never* actually located within the brain  
2.  The brain covering outside that barrier, and the scalp, are highly* sensitive to pain
3.  As was mentioned, muscles and vasculature around the face and neck often contribute to headache pain
4.  Pain can "radiate" and be perceived at some distance from the location of the injury that causes the pain -- even, indeed, in body parts that are no longer present ("phantom  limb pain" etc.).  
5.  There is a pretty strong  "blood-brain barrier" that prevents most molecules from entering (including medicines we would like to get inside!)
6.  Because of (5) there can be bad chemistry happening all over the surface of the brain covering that never gets inside to affect the brain itself.  

So just because headaches are perceptually located in or near the brain, it does not seem to follow that the brain is necessarily affected or involved.  

Is there another line of reasoning for that connection?  I'd be interested in understanding it.  Thanks.

*NOTE*   Absolute statements here are to be taken as not-quite-absolute, of course.

You should speak to your primary doctor.

"keeps it rock much longer but have a headache side effect" is just what many say about sildenafil/Viagra.

Do you know anything about what is in the pills you are considering?  Is it possible to find out?  Could it be another name for the same stuff, or a combo relying mostly on the same stuff?

T-Man Overview
T-Man is a fast acting male supplement with a subtitle of “Ying Yang Balanced Energy.” It’s promoted as an herbal vitality formula that has as its goal the harmonious balance of sexual energy.

You take it about 90 minutes before sexual activity to ensure that you are in the perfect state for your best performance when the time is right.

Some of the T-Man reviews we’ve seen from customers are very positive, comparing it to Viagra and Cialis without the chemicals or side effects.

So we thought it was definitely worth checking into.

T-Man ReviewT-Man Ingredients and How They Work
You take just one T-Man capsule about 90 minutes before having sex.

The formula contains:

Ginseng Root for improved blood flow and energy.
Tribulus Terrestris to signal a release of luteinizing hormone from the pituitary gland which then signals the testes to produce and release more testosterone.
Epimedium which increases blood flow to the penis for better, harder, longer-lasting erections.
Schisandra Fruit which is an herbal aphrodisiac for boosting sex drive.
Astragalus Root which improves erections.
Ginkgo Biloba which increases blood flow throughout the body, including the brain to improves energy and clarity of thinking.
Licorice Root which may help raise testosterone levels.
There are also some additional ingredients we weren’t familiar with.

These include Fleece Flower Root, Polygala Root, and Cherokee Rose Hips.

You are instructed to take 1 T-Man capsule about 90 minutes before sexual activity.

If you want to increase the effectiveness, you should not take T-Man within 2 hours of taking any other supplements.

T-Man Pros and Cons
A comparison of the good and bad aspects of a supplement is a great way to make a decision about whether or not to use it.

Advantages of T-Man

You don’t have to take it every day.
The ingredients are all natural, vegetarian, and they are all disclosed.
It’s pretty inexpensive to use.
There are some positive T-Man reviews from customers who’ve used it.
Disadvantages of T-Man

One reviewer says it gave him headaches.
Some of the ingredients are unfamiliar to us.
There’s really no information available about the manufacturer.

A lot of these herbal supplements are SCAMS. If they are effective it is probably because they contain generic viagra or cialis without disclosing it on the labels. "Headache" is a side effect of viagra or cialis, not broccoli.
