Statement from the Company

“Our objective with this six-supplement muscle growth line is to provide natural, non-prescription formulations with completely transparent labels,” said Stewart Lochrie, CEO at Wolfson Brands. “While published clinical literature investigates the physiological mechanisms of ingredients like D-Aspartic Acid, Ashwagandha, and standardized botanicals, consumers should recognize that studies on individual compounds do not constitute clinical trials of our multi-ingredient commercial products. We urge all consumers to combine our products with proper resistance programming and consult a medical professional prior to use.”

Ingredient Overview

Important qualification: all citations below describe research conducted under conditions unaffiliated with CrazyBulk. Several of the cited studies used specific strain designations, dosages, or delivery vehicles that differ from those used in this product. These citations establish that each ingredient has been studied. They do not constitute clinical evidence that CrazyBulk produces equivalent outcomes, and no such equivalence is claimed.

Ashwagandha Extract (D-Bal). Ashwagandha (Withania somnifera) is an adaptogenic root extract included for its evaluated effects on muscular strength adaptation and post-exercise recovery. A randomized, double-blind clinical trial published in the Journal of the International Society of Sports Nutrition (Wankhede, et al., 2015, “Examining the effect of Withania somnifera supplementation on muscle strength and recovery: a randomized controlled trial,” doi:10.1186/s12970-015-0104-9) examined muscle strength, muscle recovery markers, and body composition changes in 57 male subjects undergoing an eight-week resistance training intervention. The trial evaluated a 600 mg daily intake of standardized root extract, whereas D-Bal provides 200 mg per daily serving within a multi-component matrix.

D-Aspartic Acid (Testo-Max). D-Aspartic acid is an endogenous amino acid included for its role in neuroendocrine signaling and luteinizing hormone pathways. A clinical investigation published in Reproductive Biology and Endocrinology (Topo, et al., 2009, “The role and molecular mechanism of D-aspartic acid in the release and synthesis of LH and testosterone in humans and rats,” doi:10.1186/1477-7827-7-120) examined serum luteinizing hormone and testosterone concentrations in 23 healthy adult males over a 12-day supplementation period. The trial utilized a daily oral dose of 3,120 mg of sodium D-aspartate, compared to the 2,352 mg of free-form D-aspartic acid present in Testo-Max.

Beta-Sitosterol (Trenorol). Beta-sitosterol is a plant sterol included for its evaluated role in maintaining healthy steroid hormone ratios and lipid profile balance during physical training. A systematic review published in the British Journal of Sports Medicine (Bouic, 2001, “The role of phytosterols and phytosterolins in immune modulation: a review of the past 10 years,” doi:10.1136/bjsm.35.4.258) examined immune parameters and cortisol-to-testosterone markers in endurance athletes under severe physical stress. The clinical evaluations reviewed utilized varied phytosterol mixture concentrations, differing from the isolated 600 mg Beta-Sitosterol daily dose delivered by Trenorol.

Panax Ginseng (DecaDuro). Panax ginseng is an established herbal root extract included for its studied properties on nitric oxide synthesis, physical endurance, and muscle fatigue delay. A review published in the Journal of the International Society of Sports Nutrition (Sellami, et al., 2018, “Herbal medicine for sports: a review,” doi:10.1186/s12970-018-0218-y) examined exercise performance, antioxidant response, and recovery metrics across multiple human athletic trials. The reviewed studies utilized varying standardized ginsenoside extracts ranging from 200 mg to 1,000 mg daily, compared to the 375 mg root preparation in DecaDuro.

Tribulus Terrestris Extract (Anadrole). Tribulus terrestris is a botanical extract containing steroidal saponins, included for its traditional evaluation in physical endurance and athletic vigor support. A review published in the Journal of Dietary Supplements (Pokrywka, et al., 2014, “Insights into Tribulus terrestris which promotes human performance,” doi:10.3109/19390211.2014.887602) examined physical capacity, strength adaptations, and metabolic parameters in recreational athletes. The cited literature demonstrates that evidence is derived from heterogeneous extract concentrations, distinct from the 600 mg serving included in Anadrole.

Maca Root (HGH-X2). Maca (Lepidium meyenii) is a Peruvian root included for its historical evaluation in athletic performance, energy metabolism, and subjective well-being. A randomized pilot trial published in the Journal of Ethnopharmacology (Stone, et al., 2009, “A pilot investigation into the effect of maca supplementation on physical activity in sportsmen,” doi:10.1016/j.jep.2009.09.012) examined 40 km cycling time-trial performance in eight male athletes over a 14-day intervention. The trial administered 2,000 mg of whole maca powder daily, differing from the 200 mg concentrated extract format utilized in HGH-X2.

Format and Daily Use

Each product in the CrazyBulk muscle growth range features specific daily administration protocols designed around resistance training schedules:

  • D-Bal: Three capsules taken with water approximately 45 minutes after workout completion.

  • Testo-Max: Four capsules taken with water approximately 20 minutes before breakfast on both workout and non-workout days.

  • Trenorol: Three capsules taken with water roughly 45 minutes prior to workout sessions.

  • DecaDuro: Three capsules taken with water roughly 45 minutes prior to workout sessions; on non-workout days, one capsule is taken before the main evening meal.

  • Anadrole: Two capsules taken with water roughly 20 minutes before breakfast.

  • HGH-X2: Two capsules taken with water roughly 20 minutes before breakfast.

The manufacturer notes that dietary supplements are intended to complement structured resistance training and adequate dietary nutrition. Progressive mechanical load, adequate daily protein intake, structured recovery periods, and physician oversight remain the foundational components of muscular growth.

Market Context

The commercial expansion of CrazyBulk’s six-product muscle growth lineup coincides with steady expansion across the global performance nutrition sector:
