Is Stud (Clubhouse Stud Formula) worth it?
Worth a look (5.9/10). Stud (marketed as the Clubhouse Stud Formula) is sold by Clubhouse Supplements, the same company behind other men's health capsules on ClickBank, through a graphic-heavy video sales page reached at studperformance.com. Unusually for this category, the brand publishes a real, signed third-party Certificate of Analysis from an accredited lab (Analytical Resource Laboratories, Lehi, Utah) confirming the product is free of major pathogens and within heavy-metal safety limits, and the company's direct storefront discloses an actual Supplement Facts panel. That panel shows folate, vitamin B12 and magnesium glycinate individually and clearly dosed, but groups the three ingredients most central to the marketing story, Rhodiola rosea extract, L-theanine and taurine, into a single 600 mg proprietary blend with no individual amounts. The sales copy separately claims each of those three is dosed at 200 mg, which, if accurate, would exactly match the Rhodiola dose used in a real published clinical trial on premature ejaculation, a rare and specific match for a ClickBank product. But that split is a marketing claim, not something the legal label itself guarantees. The 180-day guarantee is long on paper but requires mailing back unopened bottles, which undercuts the "try it risk-free" pitch.
What we liked
- Real, named company (Clubhouse Supplements) with a traceable address, matching an existing reviewed product from the same brand
- Publishes an actual signed third-party Certificate of Analysis confirming safety testing and a matching magnesium dose
- The Rhodiola dose claimed in marketing (200 mg, standardized) exactly matches a real published clinical study dose
- Folate, B12 and magnesium are individually and clearly labeled
- 180-day window is long by ClickBank standards
What we didn't
- The Supplement Facts label hides the amount of Rhodiola, taurine and L-theanine in one 600 mg blend, despite marketing text claiming a specific 200 mg split
- Refund requires mailing back unopened bottles, undercutting the "risk-free" pitch
- One cited clinical study ("Verze et al., 2014") could not be verified
- Single-bottle price plus shipping is the least cost-effective way to try the product
- Sales page relies on exaggerated sexual performance promises ("BANG like an Adult Movie Star")
What is Stud (Clubhouse Stud Formula)?
Stud is a capsule supplement from Clubhouse Supplements, presented as a stamina and "last longer" formula for men. The sales page (studperformance.com) is a long video-style sales letter built around a narrative that sexual stamina depends on balancing the neurotransmitters glutamate and GABA, and that common dietary MSG intake pushes that balance the wrong way.
The company's own direct storefront (clubhousesupplements.com), run by the same business, lists six "Stamina Nutrients": Rhodiola rosea extract, methylfolate, taurine, magnesium glycinate, L-theanine and methylcobalamin (vitamin B12), and separately states a 200 mg or 200-250 mcg amount for each. The product's actual Supplement Facts label, however, only individually discloses folate, B12 and magnesium; Rhodiola, L-theanine and taurine are combined into one 600 mg proprietary blend with no per-ingredient breakdown.
The company backs the product with a signed Certificate of Analysis from Analytical Resource Laboratories (a Tentamus company), confirming the tested batch was free of E. coli, Salmonella, Staph aureus, yeast and mold, within heavy-metal limits, and that its magnesium content matched the label specification. That level of published, verifiable lab testing is more than most ClickBank supplements provide.
Format: Capsule, 60 per bottle, 2 capsules daily. Sold by: Clubhouse Supplements (sold through ClickBank).
What is on the Stud (Clubhouse Stud Formula) label?
Each row compares what the label or sales page states with what published research used. When an amount is missing, there is nothing to compare, and we say so.
Half the formula (folate, B12, magnesium) is transparently and individually dosed, and the magnesium amount is independently confirmed by the product's own lab Certificate of Analysis. The other half, including the one ingredient (Rhodiola) with a genuine dose-matched clinical study behind it, sits in an undisclosed-split proprietary blend, so buyers must take the company's separate marketing claim on faith rather than read it off the actual label.
Do the Stud (Clubhouse Stud Formula) claims hold up?
"200mg of Rhodiola Rosea Extract (3% rosavins, 1% salidrosides)"
This exact dose and standardization matches the Rhodiola rosea component of a real published trial (Cai et al., 2016) on lifelong premature ejaculation, a genuine and specific match. That trial tested a 4-ingredient combination (Rhodiola, zinc, folic acid, biotin) together, not Rhodiola alone, and Stud's own Supplement Facts label does not independently confirm the 200 mg figure since Rhodiola sits inside an undisclosed-split proprietary blend.
A 2014 study by "Paolo Verze et al." helped 90 men improve ejaculatory control using vitamin B9 (folate)
We could not independently locate a 2014 Verze study matching this description in a PubMed search. The folate-and-ejaculation research we could verify is a 2011 paper (Yin et al., Medical Hypotheses) and the 2016 Cai et al. combination trial; the specific citation on the sales page is unverified.
Sexual stamina comes down to a simple balance between glutamate and GABA, correctable mainly by avoiding MSG and taking these six nutrients
Glutamate and GABA are real neurotransmitters involved in arousal and central nervous system inhibition, but the sales page's simplified cause-and-effect story is a marketing simplification, not a mechanism validated in human trials for this specific product.
How much does Stud (Clubhouse Stud Formula) really cost?
| Option | Total | Per month | Shipping |
|---|---|---|---|
| 1 bottle | $59 | $59 | Plus a $19.95 shipping fee; not free on single-bottle orders |
| 3 bottles | $147 | $49 | Free US shipping; includes 2 free bonus guides |
| 6 bottles | $234 | $39 | Free US shipping; includes 2 free bonus guides |
A single bottle (30-day supply) costs $59 plus a $19.95 shipping fee, for about $79 total. Buying 3 bottles brings the price to $49 each ($147 total, a 90-day supply) with free shipping, and 6 bottles bring it to $39 each ($234 total, a 180-day supply), also with free shipping.
The 6-bottle price of $39 a month is competitive for this category, but it requires a $234 upfront commitment; the single-bottle option is the most expensive way to try it once shipping is included.
A single-bottle order adds a flat $19.95 shipping charge. Ordering 3 or 6 bottles ships free within the US; international shipping cost is not stated on the pages we reached.
Can you get a refund on Stud (Clubhouse Stud Formula)?
180-day window. The sales page advertises a "No Questions Asked, 180-Day Money-Back Guarantee." The company's own return instructions, however, say bottles, including any free bonus bottles, must be sent back unopened to its Tallmadge, Ohio address within 180 days of the order date, which is stricter than a simple no-questions refund and limits how much of the product you can actually try before qualifying.
Step by step: find the ClickBank receipt email, look up the order at clkbank.com and ask for a refund in writing. Our ClickBank refund guide covers returns, extra offers and auto-ship.
Which red flags did we find?
- Marketing doses don't match the legal labelThe company's own site claims 200 mg each of Rhodiola, taurine and L-theanine, but the Supplement Facts panel discloses only one combined 600 mg blend for all three, with no individual amounts.
- 180-day guarantee requires unopened bottlesRefund instructions ask for bottles, including bonus bottles, to be returned unopened, which conflicts with actually trying the product before deciding.
- Unverifiable clinical citationThe "Paolo Verze et al., 2014, 90 men" study referenced on the sales page could not be located in a PubMed search.
- High-value bonus framingTwo sexual-technique guides are advertised as a "$158 value" free bonus included with every order, a common tactic to inflate perceived deal size.
Who should buy Stud (Clubhouse Stud Formula), and who should skip it?
It may suit you if
- Men interested in a supplement that combines some individually disclosed, adequately dosed nutrients (folate, B12, magnesium) with a blend containing an ingredient (Rhodiola) that has real, dose-matched research behind it.
- Buyers who value seeing an actual third-party lab Certificate of Analysis, something most competing ClickBank supplements do not publish.
- Someone comfortable committing to a multi-bottle order and returning bottles unopened if they decide not to continue, rather than needing to test an opened bottle first.
Skip it if
- You want every ingredient amount confirmed on the legal label rather than taken from separate marketing copy.
- You expect to test the product before deciding on a refund; the guarantee requires unopened bottles.
- You are looking for citations you can verify yourself; one key study reference could not be independently confirmed.

Stud (Clubhouse Stud Formula) FAQ
Is Stud (Clubhouse Stud Formula) legit?
It is sold by a real, named company (Clubhouse Supplements) that publishes an actual third-party lab Certificate of Analysis, which is more verification than most competing products offer. Some of its marketing dose claims, however, are not fully confirmed by its own Supplement Facts label.
How much does Stud cost?
A single bottle is $59 plus $19.95 shipping. Buying 3 bottles brings it to $49 each with free shipping, and 6 bottles to $39 each, also with free shipping.
Does Stud actually help you last longer?
One of its ingredients, Rhodiola rosea, was used in a real clinical trial on premature ejaculation at a dose the marketing claims Stud also uses. That trial tested a 4-ingredient combination, not Rhodiola alone, and Stud's official label does not itself confirm the individual Rhodiola amount since it sits in an undisclosed blend.
What are the side effects of Stud?
The label advises starting slowly if sensitive to new supplements and to consult a doctor if pregnant, nursing, on medication or managing a medical condition. No product-specific side effect data is published.
How do I get a Stud refund?
The company offers a 180-day window, but its own instructions require returning bottles, including any free bonus bottles, unopened to its Ohio address within that time.
