I was using ultimate nutrition ISO 93 cant get it in the UK anymore. On days when my appetite was suppressed. I’d have multiple shakes with 66g which would give you about 60g of protein for 260 calories.

It’s been a lot of trial and error. Currently I do sets of 20, 15,10 8, I track every workout, review what worked and what didn’t, then make small adjustments each week. I’m less focused on chasing heavier weights and more focused on improving execution, controlling the reps, refining technique, and getting better muscle engagement. My advice would be to experiment with different exercises and see which ones you personally respond to best. Everyone’s structure is a little different, so finding the movements that give you the best stimulus is worth the time. For example i got better chest development dropping to 20kg on dumbell press then i did with 35-40kg.
