B12 in stacks underrated essential or unnecessary add-on?

I ran Heavy Duty for a few months and the recovery was amazing Less time in the gym but strength kept climbing

High volume always gives me a better pump but Heavy Duty seems to drive strength gains faster

The biggest challenge with Heavy Duty is pushing those all-out sets hard enough Most people stop before true failure

I’ve grown well on both Heavy Duty when life gets busy high volume when recovery and calories are high

???

Cialis pumps are insane and workouts feel much better

Metformin helped keep fat gain under control

Cialis turned average workouts into great workouts consistently
