Our verdict
SizeGenetics suits adults who want a device with a stated regulatory status, third-party testing and a long money back window, and who can pay $199.95 to $299.95 once. Cost is its weak point, with a cost score of 0.4. Everything else in the terms is stated plainly.

Pros and cons
Pros
- Regulatory status is stated: registered with the FDA in the USA and CE marked in Europe, a pairing yoummee does not match, since its terms limit it to adults, name it a GDPR compliant data controller and give no health product authorisation.
- Third-party tested is stated as yes, a mark shared by 96.8% of the brands on the site.
- A money back window of 180 days, longer than the commitment OPPA asks for, and it does not sit on a recurring billing cycle.
- Discreet shipping is stated as yes, a feature 96.2% of the brands on the site provide.
- Support runs through email, chat and phone, so phone and chat sit alongside email and a help centre.
Cons
- Fees of $199.95 to $299.95 are a single large payment, far above the €14 a month median across the site.
- The product type is device, and 22.7% of the brands on the site, so nothing repeats or ships on a schedule the way a supplement does.
- Support covers email, chat and phone only, without a community channel, which 21.5% of the brands on the site offer.
Who it suits
- Adults who want a device with a stated regulatory status and third-party testing rather than a supplement or an app.
- Readers who prefer a single payment and a money back window of 180 days over a monthly subscription.
- Anyone who wants phone and chat support as well as email, since support runs through email, chat and phone.
Who should look elsewhere
- Readers who want a monthly price near the €14.01 median, since the cost here is $199.95 to $299.95.
- Buyers looking for a supplement rather than a device; OPPA presents itself as a supplement to human contact.
- Anyone who relies on community support, since support covers email, chat and phone without a community channel.
Regulatory status and testing
SizeGenetics states that its product is registered with the FDA in the USA and carries a CE mark in Europe. That registration is the clearest separation from the brands listed beside it. Yoummee limits its terms to adults, names itself a GDPR compliant data controller, and gives no health product authorisation. OPPA takes a different position again: its terms describe the product as not a treatment product and as a supplement to human contact rather than therapy, treatment or emergency help. Both marks come from the company's own pages rather than from a licence listed on this review. Third-party tested is stated as yes, and 96.8% of the brands on the site say the same, so it is a common mark rather than a rare one. Discreet shipping is also stated as yes, a feature 96.2% of the brands on the site provide. The money back window runs 180 days, longer than the commitment a subscription brand asks for, and it is not tied to a recurring charge. For a reader weighing safety, the two marks and the testing statement are the parts worth reading closely before ordering.
Who runs it
The brand is run by DanaMedic ApS, named in the terms of service, which is the entity a reader would deal with in a query. Its headquarters country is DK, and it has been trading since 1988, a longer record than most names in the wellness category, where 126 brands are listed. That history matters for privacy and billing because it points to an established operation rather than a short-lived storefront. Support runs through email, chat and phone, covering email, chat, phone and a help centre. The spread is wider than most: 35.5% of the brands on the site offer phone support and 16.2% offer chat, so having both narrows the options. Within the wellness category, phone and help centre reach 78.1% and 80%. Billing is straightforward in structure because the product type is device sold at $199.95 to $299.95, with no subscription or monthly cycle listed, so the checkout is a single payment. Card details a reader enters are handled under the terms of service of DanaMedic ApS, the entity named in those terms.

Frequently asked questions
How much does SizeGenetics cost?+
The price is $199.95 to $299.95 for the device. That is a single payment rather than a monthly subscription, so there is no ongoing charge listed after the purchase. The cost score is 0.4, the weakest part of its profile. For scale, the median starting price across the site is €14 a month.
What does the money back guarantee cover?+
The terms of service set a money back window of 180 days, longer than the commitment most subscription brands ask for. The product type is device at a single payment, so the window is not tied to a recurring charge in the stated terms.
Is SizeGenetics a regulated medical device?+
The company states that its product is registered with the FDA in the USA and carries a CE mark in Europe. Both are marks the company puts forward for its own product. Yoummee by contrast limits its terms to adults, names itself a GDPR compliant data controller, and gives no health product authorisation.
Has the product been tested by a third party?+
Third-party tested is stated as yes on the guarantee page. That is the common position in this category, since 96.8% of the brands on the site say the same. The FDA registration and CE mark it lists are registration marks rather than a clinical result.
Where is SizeGenetics based and who runs it?+
The legal entity is DanaMedic ApS, named in the terms of service, with a headquarters country of DK and a founding year of 1988. That is a longer trading record than most names in the wellness category, where 126 brands are listed. It is a single named company behind the storefront.
How do I get help if something goes wrong?+
Support runs through email, chat and phone, so email, chat, phone and a help centre are all listed. Phone is the useful one, since 35.5% of the brands on the site offer it, and chat is scarcer at 16.2%. The list holds no community channel, and the company to deal with is DanaMedic ApS.
How discreet is the delivery?+
Discreet shipping is stated as yes on the brand's FAQ page. That is close to the norm here, since 96.2% of the brands on the site ship discreetly. What appears on a card statement is a separate question, and the shipping terms are where to look before paying $199.95 to $299.95.
How does it compare with a supplement brand?+
OPPA describes itself as not a treatment product and as a supplement to human contact rather than therapy, treatment or emergency help. SizeGenetics is a device at $199.95 to $299.95, with a money back window of 180 days and discreet shipping stated as yes. The two sit in different categories, a device with a stated regulatory status against a supplement to human contact.
