What Does Horny Goat Weed Do in SodaPeak?
Horny goat weed is the first of eight lines in the SodaPeak blend, so by label order it is the heaviest, at most 1,200 mg of the 1,200 mg total per serving. It is a traditional Chinese herb. Good trials have not shown that it helps sexual function or muscle, and the bottle prints no amount for it.
Written by the SodaPeak label deskUpdated
What is horny goat weed in SodaPeak?
Horny goat weed in SodaPeak is the leaf extract of Epimedium sagittatum, printed as the first line of the Test Boost Proprietary Blend.
The label reads "Horny Goat Weed Extract (Epimedium Sagittatum) Leaf". Its best-known compound is icariin, though the label does not say how much of it the extract holds.
The herb is used in traditional Chinese medicine and marketed for libido and stamina. That is tradition, not a test result.

Label math01
How much horny goat weed does SodaPeak contain?
The label does not say. It prints one 1,200 mg total for the whole blend, and horny goat weed is only known to weigh at most 1,200 mg of it.
A proprietary blend lists its ingredients from most to least by weight (21 CFR 101.36 (Supplement Facts, proprietary blends)). Line 1 cannot be outweighed by any other line, so the true figure sits somewhere between a small share and the full 1,200 mg.
If the eight lines were split evenly, each would get 150 mg. Because horny goat weed is listed first, it is at least as heavy as the others, so it holds at least 150 mg by this math. That floor and the 1,200 mg ceiling are limits from arithmetic, not lab results.
The full arithmetic for all eight lines is on how SodaPeak works.
Evidence02
Does horny goat weed work for sexual function or muscle?
No good trial shows that it does. Memorial Sloan Kettering lists fatigue as a traditional use that has not been tested in clinical trials (MSK, Epimedium (Horny Goat Weed)).
Sexual dysfunction is also a traditional use, and the same review says it needs more study. The only modest human signal came from a small trial on bone loss in women long past menopause.
NCCIH adds that no herbal product has definitive evidence for erectile dysfunction, and that research on each herb is limited and often done in animals (NCCIH, Sexual-Enhancement Supplements).
| Claim | What the sources say |
|---|---|
| Libido and sexual function | Traditional use; needs more study |
| Stamina and fatigue | Traditional use; not tested in clinical trials |
| Muscle | No trial found in the sources we read |
Dose03
What dose of horny goat weed do studies use?
There is no standard human dose. The sources we read give none that fits this use.
So SodaPeak's hidden amount cannot be compared with a studied one, and nobody can tell whether the extract is standardized to icariin.

Is horny goat weed safe, and who should avoid it?
It is not well studied for safety, and the reported effects are worth knowing. Sloan Kettering lists sweating or feeling hot at high doses, a rapid irregular heartbeat, mood changes and a rash from inflamed blood vessels (MSK, Epimedium (Horny Goat Weed)).
The page also says not to use it with heart disease, and to be careful with hormone-sensitive cancers.
Hormone-sensitive conditions
Ask your doctor first. Icariin may blunt aromatase inhibitors, a type of cancer drug.
Medicines the liver clears
Icariin may affect drugs handled by the CYP3A4 enzyme. The clinical meaning is unknown, so ask your pharmacist.
Never stop or change a prescribed dose because you started a supplement. Chest pain or fainting means call 911.
In context05
Should horny goat weed be the reason you buy SodaPeak?
No. It is the heaviest line by label order, but nothing shows that its weight does anything for muscle or drive.
What is fair
- Named plainly on the Supplement Facts panel
- Listed first, so no other line outweighs it
- No stimulant is listed on the label
What is missing
- No printed amount
- No trial of the product itself
- Evidence for the herb is traditional use only

Where does horny goat weed sit among the eight lines?
It is line 1 of 8. The label facts and the research sit side by side in the table below.
If low drive or erection changes bother you, a doctor can look for causes, from sleep conditions to heart disease (Mayo Clinic, Erectile Dysfunction).
| Name on the label | Horny Goat Weed Extract (Epimedium Sagittatum) Leaf |
|---|---|
| What it is | Epimedium leaf; icariin is its best-known compound |
| Place on the label | Line 1 of 8 in the 1,200 mg proprietary blend |
| Amount per serving (2 capsules) | At most 1200 mg per 2 capsules (label order); 150 mg if the eight lines were split evenly |
| What research used | No standard human dose; the only modest human signal is a small bone-loss trial in women long past menopause |
| Strength of evidence | Traditional use only; not shown in good trials for sexual function or muscle |
| Marketed or traditional use | Traditional Chinese herb, marketed for libido and stamina |

FAQ07
SodaPeak questions people ask
Is horny goat weed the main ingredient in SodaPeak?
Yes, by label order. It is line 1 of 8, so no other ingredient outweighs it. The label prints no amount for it, only a 1,200 mg total for the whole blend (21 CFR 101.36 (Supplement Facts, proprietary blends)).
What part of the horny goat weed plant does SodaPeak use?
SodaPeak lists the leaf. The label reads Horny Goat Weed Extract (Epimedium Sagittatum) Leaf. It does not say whether the extract is standardized to icariin, its best-known compound.
Does horny goat weed really work for libido?
Not shown. Libido and sexual function are traditional uses that need more study, and many trials used multi-herb formulas, so the herb alone is hard to judge (MSK, Epimedium (Horny Goat Weed)).
Can horny goat weed make you sweat or feel hot?
It can at high doses. Sloan Kettering lists sweating or feeling hot among reported effects, along with a rapid irregular heartbeat and mood changes (MSK, Epimedium (Horny Goat Weed)). The dose in SodaPeak is unknown.
Is horny goat weed safe with heart disease?
Ask a doctor before using it. The Sloan Kettering page says not to use Epimedium with heart disease (MSK, Epimedium (Horny Goat Weed)). SodaPeak contains it, and the warning panel was not in the label images we have.
Does icariin interact with cancer drugs?
It may. Icariin may blunt aromatase inhibitors, and its clinical relevance is unknown (MSK, Epimedium (Horny Goat Weed)). If you take one, show your oncologist the Supplement Facts panel before you start SodaPeak.
How much horny goat weed is in two SodaPeak capsules?
The label does not say. By label order the line weighs at most 1,200 mg per serving and, with eight lines, at least 150 mg. Those are arithmetic limits, not lab results.
