Gurunath is not a fake guru.
From what I heard from him, he has learnt under Swami Satyananda Giri and Swami Paramahansa Hariharananda Giri (both from Karar Ashram, disciples of Sri Yukteswar), also has learnt from Satya Charan Lahiri (grandson of Lahiri Mahasaya) and Shivabalayogi. Also as it is widely known, he says he has also learnt under the guidance of Shiv-Goraksha Babaji (Mahavatar Babaji from AOY), learnt directly under him, NOT as a channel-kind-of-thing as it is being written here.
His Kriya is a bit more on the agressive side than Classic Lahiri Family Kriya(more breath-retentions and bandhas, which means more prana/kundalini):
There are some slight changes on Kriya Pranayama, Navi Kriya and the Paravashta phase at the end (concentration). The rest is pretty much the same.
He also gives 2nd Kriya (Thokkar) as far as I heard, but very very rarely, basically only if you visit him for some time on his Ashram in India, and show that you are trully commited (practicing for hours and hours a day for years) plus having achieved Kechari Mudra and being stable on Vajra Nadi while doing Kriya Pranayama.
If you want to get initiated by him, that's great, he will definitely give a hugeeee boost on your practice and motivation, it will surely be an amazing experience.
But.. on the other hand, if you are considering being initiated by one of his "teachers", then better forget it and go pratice Ennio Nimis' Kriya online or AYP (add Maha Mudra before Pranayama, it will reduce 50% of the overloads, and if you still have them, perhaps focus Deep meditation mantra on the brow or solar center, it should reduce all the symptons of overload, which are mainly caused due to the non-focus-on-a-specific-part style of the mantra meditation I believe.)
The Cons are it's very expensive to go to his initiation, but I heard the money is exclusively for travel expenses/improve the ashram/feed the children that go there.
Gurunath is very serious about Kriya Yoga, but you can't consider yourself a serious student of him unless you are, at least, practicing 144 Kriya Pranayamas per day. He is very liberal in themes like food, sex, lifestyle, etc (as long as you practice every day).. but on the other side he is a bit heavy on the indian-cultural side of things related to India is the best, all the best Masters in history are from India, Jesus came to India to learn from a Nath Master, Buddha was a Yogi, Daoism came from India, etc.. all the rest of the world should thank us, go india india india! I think it's a bit over the top, but it's ok, indeed India has brought amazing things to the world.
According to the time it will take to get proper results from this Kriya (nirvikalpa samadhi), it will take some time. If you check some of his videos he says you should look into decades..
Gurunath says he has practiced around 12h per day for decades. This will put things in perspective...
