I have delayed jumping in here with my .02 worth.
Obviously, there are many different opinions on what will work (if anything) and just how quickly at that.
And, there are many who will say NOTHING works.
I have posted numerous references to my success over three years of "PE" (penis enlargement) and my advice is forget all about the word "quick".
In reality, PE works for a number of men over a considerable period of time. Using a combination of different approaches (LONG-term use of pumps, extenders, "natural stretching exercises" and jelqing) most men will (finally) see some results.
Apparently, there is some potential "built-in reserve" improvement for virtually any man to recognize by performing certain stretching maneuvers during his first couple of months (whereby some of the internal shaft begins to protrude a bit further outward due to coaxing it and loosening the tight hold of the supporting ligaments. The shaft may not necessarily "grow" as much as it just extends abit further (maybe 1/2" to possibly up to 1 full inch...that's about it for most men in using their "built-in reserve". After that...the going gets (and stays) tough for increased sizes from PE. But, progress WILL occur! -don't get me wrong...But understand...it's going to take a very, very long time with a lot of hard work and dedication.
As to pills and potions which work overnight....FORGET EM! They are "hokus-pokus".
I will concede though---some of these "chemical mixes" sometimes contain certain supplements (which you can purchase seperately in health food stores and on the web) which MIGHT assist you in growing a bigger penis when combined with the above PE methods--particularly exercises. These supplements (the really beneficial ones) increase and encourage improved circulation to the genital area which, when given vigorous exercise, will obviously benefit with more blood to heal and grow tissue. That's common sense.
The main point that I stress is...THERE IS NO QUICK WAY TO ACHIEVE A BIGGER PENIS and it certainly won't come with merely taking a pill! --At least we're not there in science just yet.
But, --maybe tomorrow?
