Seems to have worked
Once I got it, I used it once or twice, but not in conjunction with my penis pump.
So what happened?
Well I have a friend with benefits that lives several hundred miles away and we hadn't had sex in over a year. (she's a petite lady with a hot body and very tight pussy in spite of having had children)
I applied Mr Thick Dick to my shaft without sharing that info with my friend.
Once she got me hard, which takes just a few seconds, she wanted to ride me. As she straddled me and started inserting my penis into her she said "ow, that hurts" being concerned for her I started to draw back, but she would let me because she liked the sensation. As she rode me she said that I really filled her up, and wondered why I felt so thick to her. After making her cum several times (that's what I love about her, she's multi-orgasmic with me) she played with my penis as it began to get soft, wondering why it was so thick.
So for me the bottom line is, it very much did seem to make my cock thicker, which was extremely pleasant for my friend.
I'm not saying you will have the same experience, I'm just sharing that my experience was very positive. :-)
