Synful crafts a caffeine-free fat burner with HMB and leucine for muscle preservation

Synful Supplements Thermo Syn

Synful Supplements has built its catalog around bold, category-specific formulas that come with all of the ingredients and dosages necessary to get the job. In the weight management space, it already offers Jaded, Hybrid Heat, and Magma, each with its own purpose and angle. The brand is now preparing to introduce Thermo Syn, a separate and newly structured fat loss formula designed to stand alongside those existing options.

Thermo Syn is an interesting weight management innovation, as two of its biggest components are 3g of leucine and 3g of HMB to preserve muscle during a calorie deficit. You then have 1.5g of carnitine tartrate and a gram of acetyl-L-carnitine for fatty acid transport and energy production. There are some premium ingredients too, including the versatile MitoBurn at half a gram per serving, contributing metabolic support and overall fat loss.

Rounding out the other half of Synful Supplements’ Thermo Syn are the thermogenic and fluid balance components in juniper berry at 200mg, dandelion root extract, and uva ursi. Cayenne extract at 60mg, 25mg of intense ProGBB, and grains of paradise at 30mg are there to ramp up thermogenesis and get the weight loss going. There is also alpha yohimbine at 2.5mg for some stimulation, which is worth noting, as there is no caffeine in this one.

Synful Supplements interestingly combines muscle preservation, metabolic support, thermogenesis, and fluid management for Thermo Syn, a distinct balance that you don’t get in Jaded, Hybrid Heat, and Magma, which all feature caffeine. Thermo Syn is rolling out shortly, with a full 30 servings per tub in three flavors: the fruit cocktail Helix Juice, blackberry lemonade recipe Deadly Nightshade, and Mango Rush, mixing mango, passion, and lime.
