Killer Labz created Mass Monster, a multi-ingredient muscle-building supplement featuring a dual ecdysteroid pairing of turkesterone and ecdysterone. The four-capsule formula centers on 1,000 mg of Ajuga turkestanica extract containing turkesterone and 300 mg of Rhaponticum carthamoides extract containing ecdysterone. The label does not specify the extracts’ standardization levels for either compound.
The stack adds 200 mg of Laxobulk, a branded Smilax sieboldi rhizome extract, plus 100 mg of epicatechin and 50 mg of Apisterone apigenin. It also includes 10 mg of BioPerine black pepper extract, which the brand positions as an absorption aid. Each bottle contains 30 servings and is scheduled to launch Sept. 24, 2026, with an introductory discount code planned. For consumers, Mass Monster consolidates several ingredients commonly marketed for muscle size and strength into one serving.
The formula reflects demand for all-in-one sports supplements, while allowing Killer Labz to broaden its muscle-building portfolio beyond more focused products such as Killer Turk and Laxobulk.
