What Hard Steel 100K is
Hard Steel 100K is a men's herbal dietary supplement supplied as one blue capsule sealed on a single blister card. The back of the card carries a complete Supplement Facts panel: one capsule per serving, built on a 450 mg proprietary herbal blend of six botanicals. The card is distributed by Male Fuel Products, LLC of Atlanta, Georgia, and is marked as manufactured in the U.S.A.
The front of the card is black and silver, with the Hard Steel name in brushed-metal lettering and the figure 100K beneath it. The capsule sits behind a clear blister at the centre of the card and is a solid, opaque blue. Every number, ingredient name and instruction below has been transcribed from the printed card itself rather than carried over from a supplier sheet.
What is inside the 450 mg blend
The panel discloses a single 450 mg proprietary blend containing six plant ingredients, listed in this order: Epimedium brevicornum derivative, catuaba bark, muira puama root, maca root, ginkgo biloba leaf and Panax ginseng root. Because it is a proprietary blend, the manufacturer does not break out how many milligrams of each plant the 450 mg contains — only the combined total is disclosed, and we will not estimate the split. General background on how botanical supplements are formulated and labelled is available from the NIH Office of Dietary Supplements background on botanical supplements.
- Epimedium brevicornum derivative — a low, leafy perennial from East Asia, better known in supplement aisles by its common name, horny goat weed. Its leaves have a long history in traditional Chinese herbal practice and it is one of the most frequently used botanicals in men's formulas.
- Catuaba bark — bark from a small tree native to the Brazilian rainforest, traditionally prepared as an infusion in northern Brazil. The panel prints this entry as "Catuaba Bark (root)".
- Muira puama — a flowering shrub also native to the Amazon basin, where the woody root and bark are the parts traditionally used. It commonly appears alongside catuaba in Brazilian herbal preparations.
- Maca root — a hardy root crop in the mustard family, farmed above 4,000 metres in the Peruvian Andes. It is an everyday food in that region, usually dried and milled to powder before it reaches a capsule.
- Ginkgo biloba leaf — from one of the oldest surviving tree species on earth, and among the most widely sold botanical extracts anywhere. The NCCIH overview of ginkgo gives neutral background on the plant and how it has been studied. The supplement panel spells this ingredient "Ginko Biloba".
- Panax ginseng root — Asian ginseng, a slow-growing root usually cultivated for four to six years in Korea and northeastern China before harvest. Background is available in the NCCIH fact sheet on Asian ginseng.
None of the sources linked on this page has evaluated or endorsed this product; they are general reference material about the plants themselves. For a wider index of individual herbs, the NCCIH "Herbs at a Glance" index is a reasonable starting point.

How to use it
The card's directions read: take one capsule on an empty stomach 30 minutes prior to sexual activity. That is the whole of the printed instruction, and it is the only dosing guidance reproduced here.
The warning block sets a firm ceiling of one capsule in any 24 hours. That is a safety limit rather than a target. The card also states that the product must be kept out of reach of children and stored in a cool, dry place, and that a purchaser must be at least 18 years old.
Who it is for
This is a single-serving purchase aimed at adult men aged 18 and over. One capsule on one card is the format to choose if you have not used this brand before and would rather try it once than commit to a multi-pack — there is no bottle, no supply, and nothing to store beyond the one sealed blister. Browse the wider supplements for men range or the rest of our male enhancement pills if you would prefer a larger count.
It is labelled for men and is not intended for women, for anyone under 18, or for anyone who is pregnant or breastfeeding.
Good to know
The card carries an explicit interaction warning that is worth reading before you buy. It states that male enhancement products, both prescription and non-prescription, can interact with nitrates and cause very low blood pressure, and that this product must not be taken with nitroglycerin or nitrates. It also directs anyone experiencing a reaction that continues for more than four hours to go to an emergency room.
Speak to a licensed healthcare professional before use if you take prescription medication or have a heart condition, high blood pressure, or any other ongoing medical concern. General consumer guidance on choosing and using supplements safely is published by the NCCIH guide to dietary and herbal supplements.
Two practical notes from the ingredient list: the capsule shell is gelatin, so the product is not suitable for vegetarians or vegans, and it is coloured with FD&C black and white and titanium dioxide. No California Proposition 65 warning is printed on this card.
Shipping, packaging and returns
Orders leave in plain outer packaging that does not describe the contents or name the store on the outside. Product photographs are illustrative. Packaging, lot codes and printed dates vary between shipments. If the item is not right for you, our returns policy sets out the conditions and the window that applies.
Frequently asked questions
How many capsules are on the card?
One. Hard Steel 100K is supplied as a single blue capsule sealed on one blister card, and one capsule is also the full serving size printed on the Supplement Facts panel.
How often does the label allow it to be taken?
The warning on the back of the card sets a limit of one capsule in any 24 hours. No instruction for taking more than that appears anywhere on the packaging.
Does the panel say how much of each herb is included?
No. The panel discloses a 450 mg proprietary blend total and names its six plant ingredients, but it does not print an individual milligram figure for any one of them.
Is it suitable for vegetarians?
No. The Other Ingredients line lists gelatin, which is an animal-derived protein used for the capsule shell.
Who distributes it?
The back of the card reads "Distributed by: Male Fuel Products, LLC, Atlanta, GA" with the telephone number 404-552-0662, and the card is marked as manufactured in the U.S.A.
