There are some red flags for me in their process, but there is a lot of good stuff. Since I donāt like to bash things unless I know for certain thereās an issue,

EDIT: I have just discovered the testimony of someone who claimed to have birthed their yang shen from this school⦠and they have no knowledge of how to gather the inner alchemical agent that it is supposed to be made out of⦠I am leaning away from giving the benefit of a doubt in this case. It sounds like they may have a strongly qi-fortified yin shen but not an actual yang shen.
Anyways, the actual method isnāt really a secret these days:
When I was getting started with research, things were a lot less accessible. But, these days, there are actually a decent number of good resources.
Jerry Alan Johnson has good and systematic information ā he covers a whole range of things in Chinese mystical culture, including things not compatible with Neidan. But the Neidan chapters are good.
In recent years, it looks like Vitaly Filbert of Zhen Dao Pai has been on a publishing spree with various Taoist classics and commentaries. There are a lot of good things there, through the whole series.
Wang Liping is the Real Deal and more explanatory works have emerged from his students. He wrote the Ling Bao Tong Zhi Neng Nei Gong ShuāI would trust Liaoās edition above the Bartosh rendering, but either would benefit greatly from consulting the Quanzhen Classics. --Most of the focus in the book is on the preparatory work, so the dialog of Zhong and Lu and the Secret of the Golden Flower would help more with understanding the internal developments of Neidanā Filbertās Ling Bao Bifa would be good too since Wang Lipings instructions were a distillation from it).
Taoist Yoga - Alchemy and Immortality has been a monolith with technically all the information that a male person needs (some additional resources would be helpful for femalesāthe best that Iāve seen has been Filbertās volume 19 and Clearyās Immortal Sisters).
There are indeed mistaken groups out there that teach misleading or wrong information. But, if a person has a basic moral compass, it should be easy to see through the worst of those.
I think the biggest issues these days are either ābeginner mistakesā-- construing relatively limited energy phenomena with high level attainments ā or people not wanting to actually commit to the relatively monotonous rigor of training.
There were a few groups that I found that were from good lineages. Quanzhen Longmen, and some others. But they tended to write neidan off as too much work and they just focused on the taiji chuan and the social side of martial arts and ritual.
Other qigong groups tend to focus on healing, which is great but the focus is usually on forms and levels of energy body manipulation and people tend to get stuck on that and misunderstand the higher levels.
The information is out there-- but a group that is really serious about the higher levels is rare.
Note: a revision has been made to my initial written opinion at the top of this post.
