This product triggered my body to build muscle and increased my stammina. Great quality and I will repurchase as my product runs out. ### ⭐⭐⭐⭐⭐ Luceine *by C***G on 22 March 2025* Very good supplement. Gave me tons of energy. 3 pills/day, I’ve only taken two so far ### ⭐⭐⭐⭐ Easy way to get your dose *by R***N on 19 June 2014* I was looking for an easy way to consume this bitter powder. The powder never mixes well in a shaker cup and tastes horrible. The capsules are a quick, easy, and palatable way to get it down. I just wish it came in a higher dosage. Other than that, it was a perfect fit. ## Frequently Bought Together - Source Naturals L-Leucine, Energy Support*, A Free Form Essential Amino Acid Supplement for Energy Support - 240 Capsules - Nutricost HMB (Beta-Hydroxy Beta-Methylbutyrate) 1000mg (240 Capsules) - 500mg Per Capsule, 120 Servings - Gluten Free and Non-GMO - MAAC10 Ursolic Acid 50mg (100 Capsules 3X for 150mg 33-Day Serving) | Sourced from Rosemary Extract | Third-Party Lab Tested | AMPK & Sirtuin Activator --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.pa/products/472601256-source-naturals-l-leucine-500-mg-240-capsule](https://www.desertcart.com.pa/products/472601256-source-naturals-l-leucine-500-mg-240-capsule) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-09-29*
