As for the sock, I just grabbed a long sports sock and put about a pound of rice in it. This left plenty of space inside to wrap the sock around several times. It’s a constant adjustment though since you seem to get hot spots where contact is greater than other places. Temperature control I found best was by varying the pressure on the skin (more = hotter). I have a 850W microwave and just nuke it for 2 mins, then let it cool enough to use it.
I thought the heat pad would avoid this (I assumed that it would be a thin matrix of wires when in fact they are quite thick and run down the pad in a zig zag, or swirly back and forth pattern, which also gives hot spots.
The model pad I went for was the Thermofore (about 4”x17” approx). It’s okay, but I’m still looking for a better solution.
Other gadets I have are a PowerJelq, and a Jes Extender. Both of these are “nearly right” products to me, but I keep looking for their evolution to occur. I can’t wear the Jes for more than about 30 minutes as to head starts to turns dark due to lack of fresh blood. This to me would never have made it to production with such an obvious functional limitation. What I have been using it for is the cool down after heated stretching (normal room temperature).
My routine (for this past couple of weeks) has been purposefully very limited, since I want the number of excercise variables to be at the minimum:
Warm 3-4 minutes, stretch out/up/down/left/right/circular, then warm again and repeat. I do this 5 or 6 times, Then Jes for 30 mins. And that’s it! The purpose of this is not a well rounded PE routine, but to see if heat really does help, or if it just produced a one off temporary stretch.
It is important for me to know this, as I have imminent arrival of some Test gel. I’m holding off starting until I know the above results. This will be decided after 2 more weeks. After that I’ll be returning to a more robust and well rounded routine, with the Gel.
To date, I am 5/16 longer than I was 2 weeks ago. I want to know if that was merely softening and temporarily pulling out a little more, or if it is permanent stretch that can be re-built and cemented. If I don’t need the gel then I won’t use it.
Temperature (if the article is to be believed) is around 110-112F. I have no idea how to regulate this, but personally just go with as much as the skin can stand without becoming uncomfortable. I suspect this would be similar to a very hot bath.
As for supplements, I have the usual vitamins + green tea/r-ala etc, and a table spoon of MSM crystals dissolved in a GH Kick (maximuscle) shake 5 mins before going to bed.
Hope this helps.
