I haven’t finished the 8 weeks yet, currently on week 5 but I’m seeing a lot of difference in definition, size and strength. I’m doing the program while on a cut so the gains could be even better if I was on a maintenance level or surplus.
My working sets on barbell wrist curls went from 50kg to 70kg (12 reps) and my heavy barbell hold went from 100kg to 140kg (1 min)
As a Jiu Jitsu practitioner I see a lot of value in this program and recommend it, as it improved my grip strength and endurance by lots.

I began this program as a natural intermediate trainee with very little direct, regimented forearm training in my own program aside from daily dead-hangs. After completion of this program, the size and definition in my forearms is noticeable; not only that, the gains in raw grip strength have been phenomenal--strength that carries over into increasing my loads on deadlifts and pulling movements. After a deload period, I am returning for a second run-through of the program, and the gains are continuing. This program delivered far beyond expectation--forearms looking absolutely stacked in a tshirt and my actual strength has improved tremendously. My experience here has solidified my trust in Jeff Nippard's programs--I'll be back for more!

I think it's a very good program that I would definitely recommend. I believe it is a well-studied and organized program, suitable for both beginners and those who have more experience and knowledge in this sector. Congratulations for the work done and good evening.

Good program. Have been seeing some growth in forearm. Satisfied
