Quick answer
- Horny Goat Weed contains icariin and comes from traditional Chinese medicine.
- Muira Puama, "potency wood", is a traditional Amazonian vitality herb.
- Human research is limited, so they work best as part of a wider formula.
Horny Goat Weed (Epimedium)
Horny Goat Weed has been used in traditional Chinese medicine for centuries for vitality and libido. Its best-known compound, icariin, has been studied in the lab for effects on blood flow pathways. Human research is still limited.
Muira Puama (Ptychopetalum)
Muira Puama is a shrub from the Amazon rainforest, nicknamed "potency wood". Traditional healers used it for energy and desire. A few small studies suggest it may support libido, but larger trials are needed.
Why combine them?
Traditional herbs are often used together. In Boost Steel X, they sit alongside Tongkat Ali and Maca for drive, and alongside amino acids for circulation. See Tongkat Ali benefits for men.
Safety
Both herbs are generally used short term without serious issues in healthy adults, but Horny Goat Weed may affect heart rhythm and blood pressure at high doses. Check with your doctor, especially if you take heart medicine. See our safety guide.
Bottom line
These herbs are best seen as supporting players. Read our full Boost Steel X review or the ingredient list.
