With PhD Nutrition Whey HT+ I noticed gains within 2 weeks of taking it. I would take 2 servings per day, first with breakfast and the second after training. On my rest or cardio days I would just use it in the morning.
I also found that my recovery rate was improving so that with every training session, I was recovered in time for the following day's training session.
I would advice for it to be mixed with milk for an improved richer flavour and also to increase your protein intake!
