Under the hood of ALPHABULK by Olympus Labs

The list below reflects Olympus Labs' ingredient-level research claims. These are mechanistic and preclinical findings, not confirmed human outcomes, and should not be read as guarantees of muscle growth, hormone change, or fat loss for any individual.

• Multifaceted cyclic-AMP (cAMP) support
• Supports muscle protein synthesis pathways
• Supports mTOR signalling
• Supports anabolic cell signalling
• Supports lean muscle growth, in conjunction with resistance training and adequate protein intake
• Ingredients studied for a role in testicular (Leydig cell) function
• Supports recovery from training-induced muscle breakdown
• Supports strength output, in conjunction with a structured training programme
• Supports fat oxidation
• Supports lipolysis (fat breakdown)
• Supports exercise performance and recovery

ALPHABULK is built around a proposed pathway for boosting cAMP in skeletal muscle: Olfactory Receptors (ORs). ORs are best known for their role in the sense of smell, but emerging research has identified them in tissues well beyond the nose, including skeletal muscle, liver, heart, brain, and fat cells.

cAMP is a well-studied secondary messenger involved in cell signalling. In skeletal muscle, cAMP-elevating activity has been linked in research to increased protein synthesis and reduced catabolic (muscle-breakdown) signalling. Increased cAMP has also been studied for a role in fat lipolysis and oxidation, glycogen synthesis, and hormone synthesis pathways, including testosterone production via Leydig cell function.

Two of ALPHABULK's key actives, alpha-Cedrene and alpha-Ionone, are proposed to work through different OR subtypes (OR10J5 and OR51E2 respectively), both converging on the same downstream cAMP-PKA-CREB signalling pathway in skeletal muscle. Because they act through slightly different receptor subtypes, Olympus Labs' formulation rationale is that the two ingredients may work together for a greater combined effect than either alone, which is why both are included at researched dose levels.

The formula also includes Tectochrysin (via a PhytoFUSE delivery system) and Urolithin B, chosen to work alongside elevated cAMP signalling.

alpha-Cedrene: a sesquiterpene compound found in cedarwood oil, alongside other actives such as beta-cedrene, cedrol, and thujopsene. ALPHABULK uses a purified, isolated form of alpha-Cedrene, studied as an agonist of the OR10J5 receptor subtype, which has been associated in research with increases in cAMP in skeletal muscle and fat cells.

alpha-Ionone: part of the ionone family of aroma compounds found in trace amounts in various essential oils and fruits. ALPHABULK uses a purified, isolated form of alpha-Ionone, studied for a potential role in myogenesis (new muscle fibre formation) and in reducing markers of skeletal muscle atrophy, via the OR51E2 receptor subtype.

Both alpha-Cedrene and alpha-Ionone are described in the cited research as orally bioavailable and as accumulating in skeletal muscle, fat, and liver tissue. Studies referenced by Olympus Labs report changes in downstream signalling molecules linked to anabolic and catabolic balance (including PKA, CREB, FoxO3, and PGC-1alpha on the anabolic side, and MuRF1 and MAFbx on the catabolic side), along with effects on glucose uptake and insulin sensitivity in the models studied. This research is at the mechanistic and preclinical stage; it describes how the ingredients are proposed to act, not a guaranteed outcome for any individual.

Tectochrysin (PhytoFUSE): a methoxyflavone derived from Black Ginger root. Research cited by Olympus Labs identifies Tectochrysin as the most potent of the methoxyflavones studied for skeletal muscle hypertrophy in that research, with reported effects on protein synthesis, nitrogen retention, muscle endurance, recovery, and ATP production. The PhytoFUSE delivery system is Olympus Labs' proprietary technology intended to improve the bioavailability and duration of action of compounds like Tectochrysin.

Urolithin B: one of four metabolites of ellagic acid and ellagitannins. Research cited by Olympus Labs reports that ellagitannin supplementation reduced markers of exercise-induced muscle damage and protected muscle tissue under high-fat-diet stress in the models studied, and that Urolithin B supported myotube growth and differentiation, inhibited the ubiquitin-proteasome pathway (a mechanism of protein breakdown), and reduced markers of muscle atrophy in laboratory research. This research was conducted in cell and animal models rather than human trials, and specific potency comparisons to testosterone from that research have been left out of this summary as not appropriate for supplement marketing.
