My experience with recent INSCYD:
Pros:
- much faster, easier, less invasive
- gave me nutrition/fueling data that I would not have gotten from traditional lab testing
- didn’t need to travel
- no needles, masks, etc
- can repeat protocol if you (for example) didn’t quite get the sprint right
- I’ve nearly forgotten how to spell FTP. I have what I consider more “realistic” training zones. And they are much simpler to use in training.
Cons:
- not sure what to do after a block of training. I’m not going to pay another fee to do the testing again (at least for awhile) to see if I improved. Not sure you are supposed to anyway. Also, I don’t really feel the need to obsess about FTP any more (good), but how do I measure regular progress?
- had to just guess my body composition
- most places will give you cursory training advice but you’ll have to handle getting really detailed training direction separately.
Also, there are some threads where ppl are trying to reverse-engineer the VLamax calculation, but that calculation didn’t work for my actual numbers.
