The Fundamentals
What Are
Prohormones?
Prohormones are precursor compounds that convert into active hormones in the body through enzymatic processes. Unlike anabolic steroids, prohormones work with your body's natural pathways to support increased muscle protein synthesis, strength output, and body composition improvements.
They're the go-to for experienced lifters who want to push past natural plateaus without resorting to more aggressive compounds. At AO Nutrition, we only stock prohormones from manufacturers who provide third-party testing and use clinically studied ingredients at effective dosages.
No proprietary blends. No mystery formulas. Just transparent labels and real results.
Find Your Fit
How to Choose
the Right One
For Bulking
Compounds that support nitrogen retention and glycogen storage. Pair with a caloric surplus and progressive overload for maximum size and strength gains.
For Cutting
Preserve lean tissue during a deficit while supporting fat oxidation. Ideal for pre-competition prep or dialing in body composition.
For Recomp
Build muscle and reduce body fat simultaneously. Works best at maintenance calories with high protein and intense training.
For Beginners
Start mild, assess tolerance, then move to stronger formulations. Always run proper PCT afterward. We can help you build the right first cycle.

Don't Skip PCT
Every prohormone cycle must be followed by proper Post Cycle Therapy. PCT supplements restore natural hormone production, protect liver health, and lock in the gains you made during your cycle. We carry a full line of PCT products designed to pair with any prohormone stack.
