I’ve tried the Pro Clinical version for about 8 weeks last year, keeping my routine steady (calories at maintenance, 10k steps daily, resistance training 4x/week). Waist dropped 1.5 inches (from 36 to 34.5), and my bioimpedance scale showed a 2% trunk fat reduction-felt like it targeted the stubborn lower belly more than overall bloat. No DEXA, but clothes fit looser around the midsection without major scale changes.
Side effects: Mild jitters first week (like an extra espresso), but no sleep issues if taken before noon. GI was fine, no anxiety spikes. Ingredients-wise, it’s got a decent dose of C. canephora robusta (green coffee bean extract) at 200mg, which some small studies link to visceral fat loss, but the proprietary blend hides exact EGCG amounts-haven’t seen third-party tests, but Labdoor rates it middling for purity.
Stacked it with morning coffee once; turned into afternoon crash city, so I skipped that. Paired with glucomannan (1g pre-meals) and noticed better appetite control, maybe an extra inch off waist over time. Tolerance built by week 4, so cycled off/on.
On your curveballs: Yes, poor sleep from work stress undid half the progress-cortisol is brutal for visceral fat. Tracked resting HR; it bumped 5-7 bpm on days I took it, back to baseline off. No hypertension here, but if you’re on SSRIs, watch for serotonin interactions with any caffeine load.
Love the n-of-1 trial idea-count me in if you set it up. Simpler caffeine + EGCG (200mg each) gave me similar results cheaper, but Hydroxycut’s robusta edge felt slightly better for targeted fat. Receipts: My before/after waist tapes are in my profile pics if you search my posts.
