I hung for about 4 months with Bib-starter.
Gains mostly in flaccid length (about 0.3 – 0.4 inches), Erected length only between 1/16 and 1/8 inch.
I hung 4-6 sets a day, 20 min. each - 6 days a week.
SD – max. weight 20 lb.
SO – max weight 22.5 lb.
Most of the time I hung SO because of my low LOT using between 17.5 and 20 lb.
I started with 6 lb and increased the weight with about 1-2 lb. every week.
I am uncut and had a lot of issues with foreskin irritation and bulge on the rim of the foreskin that took 3 weeks to disappear. Since then every time I start hanging after the 1st set it comes again. Therefore I had to stop hanging and return to manual stretches.
I’m disappointed with hanging, but I suspect that my foreskin kept me from having good gains. If I were circumcised I could have hung for 3-4 hours a day and gained in this 4 months period at least 1/4 EL (not so fast as some of the people here report, but this depends on the LOT, mine is extremely low - between 6 and 6:30 o’clock).
