THE cannibalistic ringleader of a "Eunuch maker" gang who chopped off victims' genitals to stream on a body modification site has been jailed.
Marius Gustavson, 46, ate cooked testicles for lunch in an "artfully arranged salad platter".
The Norwegian national also masterminded a "lucrative" website where 22,841 users paid to watch men having their privates removed so they could become "nullos".
Gustavson made almost £300,000 through the extreme site, with some punters forking out £100-a-year subscriptions.
In one shocking video, the Eunuch maker - who had his own penis cut off, the tip of his nipple removed and his leg frozen so that it had to be amputated - is seen "tasting" a man's severed genitals.
Body parts were also kept in a freezer at his North London home and his own manhood was discovered in a drawer four years after he sliced it off.

Gustavson has now been jailed for life with a minimum of 22 years after admitting conspiracy to commit grievous bodily harm and five counts of grievous bodily harm with intent.
He also pleaded guilty to one count of making an indecent photograph of a child, one count of distributing an indecent photograph of a child and possession of criminal property.
Gustavson was described as an "arch manipulator" who recruited like-minded individuals to assist him with his gruesome work.
This included ten men who have been charged over their involvement in the procedures.

David Carruthers, 61, Janus Atkin, 37, Peter Wates, 67 and Ion Ciucur, 30, previously pleaded guilty to conspiracy to commit grievous bodily harm between 2016 and 2022.
While Ashley Williams, 32, and Stefan Scharf, 61, also pleaded guilty to causing grievous bodily harm with intent.
The Old Bailey heard some of the severed body parts were sold, while others may have been eaten by Gustavson.
Prosecutor Caroline Carberry KC said there was evidence of "cannibalism" - with one video showing how he cooked testicles for lunch.
She added: "The images, from raw ingredients to an artfully arranged salad platter, were discovered by officers."
Gustavson carried out the procedures at his home in London, as well as in rented apartments or hotels.
As well as the money he made from the site, he also scrounged £18,500 in disability benefits after amputating his leg.
The group used a "wide variety of tools" for their procedures - including those used for "animal castration".
The 13 victims - including a 16-year-old boy - were promised money from the video revenue.
Although many of the men consented to the surgery, some were "tricked" or under the influence of drugs at the time.
During a facetime call with a man in Sweden, Gustavson told him to "maim himself" by cutting off his testicles with a knife.
Gustavson told him: "You know what to do come on, just push it."
Another victim was branded with the letters "EM", for eunuch maker, on the back of his calf.
One victim claimed Gustavson created a "cult-like atmosphere" around him, which was "captivating and mesmerising".
The man, whose testimony sparked a police probe in 2019, said he was left feeling like a "monster, a mug, a degenerate and a freak".
Rashvinderjeet Panesar, defending Gustavson, said the breakdown of his 11 year marriage in 2016, which had "kept him stable", was a "trigger" for his extreme activities.
He added: "He had a desire to be the architect of his own body.
"His modification led him to feelings of empowerment.
