Well for my own penis 2500 hours since Nov 2018. First 500 gained 1/3 nd and inch. Next 2000 nothing really , according to the ruler. Went from 3 to 31 lbs in three years very slowly . Hung from 7-14 hours , weekly average best about 9, hrs weekly, in these six years. Been consistent, haven’t stopped once.
If it is collagen toughness say an 8 on a 0-10 scale, I’d need 35-40 lbs to increase length. According to this most easy gainer, would have 5 or lower . Bib who I’ve worked a lot with has about a 1.5, which he says was terrible for everyday life, he’d get injured super easily but for his penis an obvious advantage.
Other than that, a couple articles stating primobolin, deca, anavar and equipoise increase collagen synthesis. Testosterone at 200 or lower increases and above 200 decreased .
