Xtremis Cartel operates in the premium end of the sports nutrition market, putting together supplements that lean heavily on loaded formulas, including high-end, reliable ingredients. The brand plays in many key sports nutrition categories, especially the main ones like pre-workout, aminos, and weight loss. It also has muscle-building products, like the testosterone booster Macho, which now has a partner it can be stacked with for even greater results in Fuerte.
In typical Xtremis Cartel fashion, its Fuerte muscle builder packs plenty of power, and leading it all off is a full 2.4g of proven PeptiStrong, a fava bean protein hydrolysate shown to activate muscle protein synthesis and support anabolic signaling. Complementing that is 2g of DL-185, a dileucine compound from NNB Nutrition that works through a similar pathway, stimulating muscle protein synthesis much more effectively than standard leucine.

Rounding out the muscle-building load out of Xtremis Cartel’s Fuerte is 300mg of Epicatelean epicatechin, supporting lean mass and strength, and 150mg of another branded component in GG-Gold trans-geranylgeraniol, an ingredient that plays a role in supporting testosterone levels. BioPerine closes out the combination at double or even quadruple what we usually see it at, with 20mg, to improve absorption and overall efficacy.
Xtremis Cartel has priced its all-new muscle-builder, Fuerte, the same as Macho at $69.99 for a full-size bottle of 300 capsules, which works out to the usual month’s supply of 30 servings. Again, it can be stacked perfectly with Macho for even greater strength, growth, and recovery results, and the brand offers discounts if you do. The parent retailer NutriCartel is offering 10% off if you grab the two together, bringing the two down to $62.99 each.
