Hi "Relax"
I still have bottles of niacin in my drawer that are maybe 18 months old. And they still work, but there are many factors.
One of the things that has become very obvious with almost any of our remedies for POIS, is that we are in a very unstable "testing environment".
I think my use of niacin shone some light on this (becasue it is so finicky). I had fairly good instructions when I first tried it, but it was still not consistent, so I wondered why.
Long to short, experimentation zeroed in on a more stable procedure.
We don't know why it works, there's a thread right now that says it's becasue of it's vasodilation characteristics, which probably is close to the mark. AND it does seem that other vasodilation elements also help significantly. However, it doesn't help everyone, and I wonder if that has more to do with the procedure or it's actual function.
If we knew why it worked, really, it would help our research. We would know exactly HOW to take it and what the effects of expiry date are etc.
Anyways, back to expiry dates.
I have found that if the niacin is least exposed to the air, it lasts quite a long time. It may loose a little potency, but generally is stil quite useful for a good 2 yrs.
At this time I am using it with viagra (because I need viagra) and the viagra enhances niacins effect, but you do have to be carefull, because they are mutually enhancing. Viagra side effects are stronger with niacin, and the niacin flush is very much greater with viagra. With viagra I don't need to take more than 50mg niacin. Wouldn't want to. 100 mg niacin with viagra gives you a very strong flush that lasts more than an hour. Not at all pleasant.
So keep the niacin in closed airtight bottles, the smaller the better, at room temp without light, and it lasts for quite some time. It seems
better to have at least 20 or more capsule in one bottle.
I put two or three capsules wrapped tightly in aluninium foil, and it didn't seem to last more than about 3 months.
I've got quite a challenge for you!!!! It may seem that one thing conflicts with the other, but see what happens.
It involves meditating through the transition form normal, through masturbation and on to POIS onset.
Do it with niacin. So you'd be able to take the niacin, maybe before the flush starts, begin meditating, and follow what's going on inside you. Somehow, "pause to masturbate" (the difficult part) and then follow through as cleanly as possible in meditation. Try to feel what's happening inside, where the niacin comes into play...
The meditative state is quite observant!
