What it is
Stiff Rock is a herbal dietary supplement for adult men, supplied as one red capsule sealed on a single blister card. The Supplement Facts panel printed on the reverse of the card gives a serving size of one capsule and a single proprietary herbal blend totalling 1,200 mg, with eight named entries listed beneath it. The card is distributed by Steele Products of Hallandale, Florida.
The capsule is deep red and sits behind the clear blister window on the face of the card, which describes the contents as a single dose. The barcode printed beside the panel reads 608011503512, which is the UPC carried on this listing.
What's inside
Every entry on this panel sits inside one proprietary blend, so the label publishes a combined figure of 1,200 mg and no separate milligram amount for any individual ingredient. That is the manufacturer's chosen level of disclosure, and it is worth knowing before you compare this card against a panel that itemises line by line: the quantity of any one entry below is not printed anywhere on the packaging, and it is not stated here either. What follows describes each entry as the panel names it — what the ingredient is and where it comes from — and nothing about what the capsule will do for the person who takes it. The NIH Office of Dietary Supplements publishes a general primer on botanical dietary supplements that covers how blends of this kind are put together and labelled.
- Tribulus — a low, spreading annual of the caltrop family that colonises dry, disturbed ground across southern Europe, Africa and Asia, and has naturalised widely in the warmer parts of North America. The hard, spiny seed cases are the part usually dried and milled. The panel prints the genus on its own, without a species name beside it.
- Cordyceps Militaris — a bright orange, club-shaped fungus that in the wild fruits from buried moth and butterfly pupae in temperate woodland across Asia, Europe and North America. Almost all of the material used in supplements today is farmed on grain or rice substrate under controlled conditions rather than collected from the field.
- Ginger Root — Zingiber officinale, the knobbly underground rhizome of a tropical flowering plant in the same family as turmeric and cardamom. India, China and Nigeria grow most of the world's crop, and the same rhizome is a kitchen staple across South and East Asian cooking.
- Cnidimum and Monnier Extract — the panel prints these as two consecutive entries and gives no botanical species for either. Because the label offers no identification, none is offered here; the names appear above and in the table below exactly as they are printed on the card.
- Theobromine — the one entry on the list that is not a plant part. It is a bitter alkaloid that occurs naturally in cacao beans, and so in chocolate, as well as in tea leaves and kola nuts. Chemically it is a close relative of caffeine, which is worth noting if you are sensitive to that family of compounds.
- Rhodiola — Rhodiola rosea, a stubby, succulent-leaved perennial that grows on cold rock ledges and sea cliffs from Scandinavia and Siberia through to the Rocky Mountains. The thick root is the part dried and extracted, and it has a long documented history in Scandinavian and Russian folk practice.
- Avena Sativa Extract — common oats, the same species grown as a cereal crop. The extract used in supplement formulas is normally drawn from the green, immature plant rather than from the harvested grain, and is sometimes sold under the older name wild oat extract.
NCCIH maintains plain-language summaries of many of these plants in its Herbs at a Glance index, which is a reasonable place to read general background on a botanical before buying anything that contains it.

How to use it
The directions printed on the card are to take one capsule 45 minutes prior to sexual activity. The caution line sets a single hard limit beside them: do not exceed more than one capsule in four days. That interval is wider than many people expect from a supplement, so it is worth reading twice — there is no daily schedule on this label, no loading period and no second serving.
The card also states plainly that the product is not for use by individuals under the age of 18 years.
Leave the capsule sealed in its blister until you intend to use it, and keep the card somewhere cool, dry and out of direct sunlight. Nothing on the packaging asks for refrigeration.
Who it's for
This is a single-serving product for adults 18 and over. The one-capsule format suits two people in particular: someone trying this brand for the first time who would rather not commit to a multi-count pack, and someone who prefers to keep one sealed card in a drawer over storing an opened bottle. Because the listing is one sealed serving, there is nothing to portion out and nothing left over.
If you already know you want a supply rather than a single card, the multi-count formats sit in Supplements for Men, and the wider Male Enhancement Pills range covers the other brands stocked alongside this one.
Good to know
Read the warning printed on the card before you buy, because it is specific rather than generic. The manufacturer states: use only as directed; do not take this product if you have a serious medical condition or take nitrates, nitroglycerin, or prescription medications; do not use if you have heart problems or high blood pressure; and consult your physician if you have any of these medical conditions. The nitrate line in particular is not boilerplate — if you take nitroglycerin or any other nitrate medication, the card tells you this product is not for you.
Two details on the ingredient list are worth flagging for people who read labels closely. The capsule is coloured with FD&C Red #40 and titanium dioxide, so it is not a dye-free product, and theobromine belongs to the same chemical family as caffeine. Neither point is a problem in itself; both are the kind of detail you would want in front of you rather than behind you.
More generally, a supplement is not risk-free simply because its ingredients are botanical, and a proprietary blend gives you less to work with than an itemised panel does. The NCCIH overview of dietary and herbal supplements is a sensible starting point on quality and interactions, and the NIH Office of Dietary Supplements page on what you need to know about dietary supplements covers the questions worth asking of any product in this category.
Keep the card out of reach of children. Gear Isle is the retailer here, not the manufacturer; this product is distributed by Steele Products of Hallandale, Florida.
Shipping and packaging
Every order leaves in unmarked outer packaging. Nothing on the outside names the contents, and it will not show the Gear Isle name. Orders placed on a working day go out the next working day, and quicker carrier services can be chosen at checkout.
Frequently asked questions
How many capsules come with this listing?
One. This listing is a single red capsule sealed on one blister card, and the Supplement Facts panel gives a serving size of one capsule.
Does the label say how much Tribulus or Rhodiola the capsule contains?
No. All eight entries are grouped into one proprietary herbal blend of 1,200 mg, and no individual milligram amount is printed for any of them. If a per-ingredient breakdown matters to you, this panel will not give you one.
How far apart does the label say servings should be?
The caution line on the card reads: do not exceed more than one capsule in four days. That is the manufacturer's stated limit, and the directions add that the capsule is taken 45 minutes prior to sexual activity.
Does the capsule contain artificial colouring?
Yes. The other-ingredients line names FD&C Red #40 and titanium dioxide alongside cellulose, magnesium stearate and silica. That is what gives the capsule its deep red shell.
Can I take this alongside prescription medication?
Not without asking a doctor or pharmacist first. The card is explicit that the product should not be taken by anyone using nitrates, nitroglycerin or prescription medications, or by anyone with heart problems or high blood pressure. Bring the ingredient list to that conversation.
