HorseMood Horny Goat Weed: The First Ingredient in the Blend
Horny goat weed is the first name on the HorseMood panel. This post covers which plant it is, what its first place in the blend tells you, the compound it is known for and the questions to raise before you start.
HorseMood lists horny goat weed extract (Epimedium sagittatum, leaf) first of the eight ingredients in its 1,200 mg Test Boost blend. First place means it weighs the most of the eight, so it could be up to the full 1,200 mg, but its exact amount is not printed. The plant is known for a compound called icariin.
What is horny goat weed in HorseMood?
Horny goat weed is a leafy herb from the Epimedium family. On the HorseMood Supplement Facts panel it appears as Horny Goat Weed Extract (Epimedium Sagittatum) Leaf. It is the first of eight ingredients in the Test Boost Proprietary Blend, which totals 1,200 mg per serving of two capsules.
The panel names the plant species and the plant part. That is a useful detail. The leaf is the part of Epimedium most often used in supplements, and naming it tells you exactly which material went into the extract.
Horny goat weed has a long place in traditional Chinese practice, and it is one of the most common herbs in men's formulas. In HorseMood it sits next to tongkat ali, saw palmetto, nettle root, wild yam, sarsaparilla, orchic substance and boron. See the ingredients page for all eight.

What its first place on the label tells you
A proprietary blend lists its ingredients in descending order by weight. That rule turns the printed order into a small piece of real information.
- Horny goat weed weighs the most of the eight ingredients in HorseMood.
- It could be any amount up to the full 1,200 mg, but no single amount is printed.
- Tongkat ali, in second place, can be at most 600 mg. Boron, in last place, can be at most 150 mg.
These figures are ceilings, not amounts. They are the only numbers the arithmetic allows, and they are why the site never states a single milligram figure for horny goat weed. The supplement facts page transcribes the full panel.
Icariin, the compound behind horny goat weed
Horny goat weed is best known for icariin, a compound found in Epimedium leaves. When people talk about what horny goat weed does, icariin is usually what they mean.
Research on icariin has looked closely at how the body takes it up. A 2019 randomised, double-blind, placebo-controlled human trial, described on our ingredients page, gave icariin from 100 mg up to 1,680 mg and measured blood levels. Levels stayed very low, with nearly all samples below 1 ng/mL. So the open question for this herb is absorption, more than dose.
The HorseMood label does not print an icariin percentage for its extract. That is common for blends, and it means the panel tells you the plant and the part, but not how much icariin a capsule holds.
How horny goat weed fits the rest of the HorseMood blend
HorseMood combines horny goat weed with seven other ingredients rather than selling it alone. Read as groups, the blend has a clear shape.
- Horny goat weed and tongkat ali lead the list. Both are classic men's herbs with a long traditional history.
- Saw palmetto and nettle root follow. Both are well known in men's health products.
- Wild yam, sarsaparilla, orchic substance and boron close the list.
The whole blend is taken as the label says: one or two capsules daily with an 8 oz glass of water. Two capsules is one full serving of 1,200 mg, and one capsule is half of that. The how to use page explains the choice.

Our view
Horny goat weed is the lead ingredient in HorseMood: first on the panel, the largest share of the 1,200 mg blend, and named down to the species and the leaf. It is a classic men's herb with a long traditional history, and icariin is the compound it is known for.
The label keeps its exact amount private, so the best way to judge it is the way the site suggests for every ingredient: read the panel, show it to a pharmacist if you take medicine, and follow the one or two capsule instruction.
