 Has anyone used L-arginne combined with Pycnogenol for erectile disfunction? If so I'd appreciate any comments and a daily protocol..Thanks...Pete

Pete........I know that L-Arginine helps dilate the blood vessels, but I have not tried it for ED. Ditto for regimen has been 100 mgs of Viagra almost nightly for about 18 months, with MD's blessing. I've been seeing progress, albeit slowly, and I still believe there's more room for improvement.

I have used 2000mg L-arginne with my generic viagra for 3 years now.  It is supposed to allow for better adsorption of the pills chemicals, thru nitric acid release (I think, I've forgotten the technical action of it).  Can't say it helps, doesn't seem to have hurt, my condition remains a condition rather than an improvement... blush

I have been taking OPC (containing Pycnogenol) for some time, and have just started with L-arginne.

I reduced my PSA by taking OPCxtra prior to being "Cut"

It is wishfull thinking that there is a 2.35% ED improvement..  , since starting on the L-A 

WE - will both be hoping that there is a benefit - but - I have a personal belief that the consmption of OPC will reduce the chance of cancer resurfacing.....  THAT - is far more important !!!

There IS a belief that L-A should have an appropriate ED effect..... :-)

I have talked to people in the supplement field. They all told me that any of the L-Arginine that we are taking OTC is not enough to substantially raise the nitric oxide levels enough to make an appreciable difference. They offered a few other solutions that included body building supplements which supposedly release much more nitric oxide - but beware, all these things also raise testosterone levels which may be a higher cancer risk.
Go to one of the trusted supplement stores and find some guy there who is knowledgable about this stuff. It may take some searching - I had to visit four stores before i found anyone who really seemed competent.
My two cents is that anytime we get into serious supplements we are taking some risks for guys in our position. For a normal, healthy functioning penis, a bit of L-Arginine may create some firmer erections, it won't really make a difference when we are dealing with nerve damage and/or compromised blood flow.

FYI, as little as 1/4 up of walnuts provides 2 grams of L-Arginine, plus some omega-3's as well

Paul is correct a single 1000mg pill of L-Arginine is not going to do a whole lot, you may get some benefits if you take it 1/2 hr Prior to taking a Viagra. Problem with eating walnuts before taking Viagra is the fat in the walnuts prevents Viagra from being absorbed properly

Also note there are four different versions of Arginine

1) L-Arginine in its basic form, not highly absorbed by the intestine
2) L-Arginine Alpha-Ketoglutarate which is substantially more absorbed by the intestine
3) L-Arginine Ethyl Ester DiHCl which has the maximum bioavailability
4) Di-Arginine Malate an ultra pure Pharmaceutical grade enhanced version

going into any supermarket you will easily find number 1 ( least effective and a waste of time IMHO) , a GNC or bodybuilding website will get you 2 and 3. For number 4 you would have to go to a pharmaceutical supply store or there are a few website where you can get it

If you were going to take just a 1000mg pill number 2 or 3 gives you the most amount of Arginine in your bloodstream working for you.

NOTE : If you have BP issue Arginine will lower BP temporarily so be careful

As I mentioned previously , I have only recently started on LArg-AK...  I purchased on-line, a 1Kg jar of powder..
Does anyone know what would be a good general morning 'supplement' level?
I think that I used a bit too much this AM in my protein shake and the old head went a bit fuzzy after a time. (drop in BP???)

I note a comment that LArg.. could increase Testosterone.  I was a little concerned at this observation, as I am over-normal, even now, and so EXTRA would not be a good thing. (not that it does any good -   HeHe ..)

I have taken significant doses of OPC (containing Pycnogenol or Pine-Bark Extract) prior to surgery, and it did actually drop my PSA, when it should have risen.  I now take two units a day, as does the bride..
I continually read that there is no known "Unsafe" daily amount..  I know a chap who IS reducing his Brain Cancer via  OPC consumption.

I take 1000 mg L-Arginine daily. I get full natural erections without meds. I do not know if it is the L-Arginine but
I am afraid to stop taking it. LOL.
I have not read of any problems taking it, side effects etc.

After Petelg mentioned using Pycnogenol (Pine Bark Extract) along with L-Arginine I figured I would try the two of them together along with my daily Cialis. I had run out of Vasoflow pills back in the spring and then they went off the market but I finally located some L-Arginine Ethyl Ester Malate.
Been using PureBulk website for this since they are pretty no frills but a lot of good helpful info. Got the Pine Bark Extract there too. (By the way they are manufactured in China .. might have to think about that if ordering -- but at least they are up front and tell you the origin).

Over the last couple of weeks taken 1 Bark @ 500mg and around 1200mg l-Arg @ around 11 pm with either ED pill at the same time or a 2-3 hrs later.

So far have had sporadic nocturnals ... can't say that they are any more reliable or frequent.

But I've got 300 capsiules of bark extract and 8 oz of L-arg powder to go thru (and of course unlimited numbers of pills) so will keep on for the time being with various combos and timing.

Better living through chemistry, eh?
