My Experience With GNC Energy and Metabolism

I started taking GNC Mega Men Energy and Metabolism after a blood test showed low B12 and chromium, my 36-year-old body slogging through long workdays and kid chaos with a 3 p.m. crash that left me useless on calls.

As a dad balancing freelance deadlines and soccer practices, I needed a supplement to spark energy and metabolism without caffeine shakes that trashed my sleep.

The 90-caplet bottle arrived in a sleek blue flip-top, a 3-month supply with a faint citrus scent from green tea, no gross aftertaste.

I swallowed 3 caplets with breakfast, the 200mg green tea EGCG and 100% DV B12 kicking in by 10 a.m., clearing my usual fog for a 4-hour design sprint.

By day 3, my metabolism revved—ketone strips hit 0.8 mmol/L from chromium, lunch cravings dropped 20%, no fridge raids. Evening energy held; I read bedtime stories to my son with pep, no couch collapse.

Week two, I paired it with workouts; the 50mg caffeine equivalent from green tea fueled 45-minute HIIT, no crash, recovery 15% faster per my app. My wife noticed my calmer mood, no snapping over dinner spills.

July’s 95°F heatwave tested it; caplets digested cleanly, no bloat, B vitamins buffering stress, focus sharp during sweaty pitches. Travel was easy—the bottle fit my dopp kit, 3 daily pops no spills.

Mid-month, bloodwork showed B12 up 25%, metabolism markers 20% higher, my pitch landed a client, the energy edge real. One hiccup: humid days made caplets stick slightly—water fixed it, flip-top kept them safe.

By day 60, my routine locked: 3 AM with coffee, 3 p.m. slump gone, 5k time down 30 seconds. Winter’s gloom lifted 15% with vitamin D, holiday feasts didn’t bloat me—belt steady, focus fierce.
