For now decided to forego the pre, getting whey and looking at intra-workout - something like the nutritech amino boost 2.0 OR npl bcaa 10:1:1 - I'm almost certain these things are placebo (to a certain extent), but since it's my first time I don't mind buying a tub and seeing if it actually helps with stamina during workouts, and since it contains glutamine, means I won't need to drink the Primal L-glutamine I was having before separately.
Someone recommended Evolve Nutrition Prolong to me, but not finding it on Takealot etc.
