How are peptide brands advertising on Meta? I got the pitch.

If you sell research peptides, you have been told that paid social is closed to you. And then you open Instagram and see a competitor running a carousel for BPC-157 with a discount code on it.

That contradiction bothered me for a long time, so when an agency pitched me on running exactly those campaigns, I took the call and asked for the deck. This is what was actually in it, and why I said no. I am not naming the agency, because the point here is the model rather than the firm, and there are several running it.

The offer

The structure was straightforward:

• $5,000 per month management retainer
• 5% of total ad spend on top
• Suggested media budget of $100 per day, described as running “until positive ROAS is defined, then scale to the moon”
• Optional add-ons for SEO and Google Ads

The deck was good. Professional design, a clear sense of the category, real understanding of how peptide buyers think. The case study showed just over $10,500 in spend producing about $36,000 in sales: a 3.43 return on ad spend and a $61.11 customer acquisition cost. The lifetime value column was blank, and the slide noted that verified client metrics were available on request, which is another way of saying the numbers were not verifiable at the time I was being asked to decide.

Then I read the deliverables line in the onboarding email: creatives, management, agency ad accounts, link cloaking.

That last item is the whole answer

Link cloaking means showing the platform's ad reviewer one page while showing real users a different one. The reviewer sees something clean and compliant. The customer clicks the same ad and lands on the actual sales page.

Meta prohibits this, and it is not a minor infraction. Cloaking is treated as deliberate deception of the review system, and the documented consequence is permanent loss of accounts rather than a warning or a rejected ad.

So the answer to “how are these brands advertising on Meta?” is not that they found a clever targeting angle or a compliant way to phrase a claim. There is no technique a competent in-house buyer is missing. The edge is a willingness to break the platform's rules on your behalf, and to treat account bans as a normal operating cost.

Once you see it that way, the rest of the offer explains itself.

Why campaigns run on their accounts, not yours

“Agency ad accounts” sounds like a convenience, maybe even a perk. It is the tell.

Campaigns run on a stable of aged business accounts the agency controls, because those accounts get banned on a regular basis and need replacing. You are renting disposable infrastructure. If the model produced durable, approvable campaigns, running them on your own account would be the obvious default, and it would be better for you, because you would keep the pixel history and the learning.

Ask yourself why a service would be architected around the assumption that its accounts will be destroyed.

Where the risk actually lands

This is the part that decided it for me. The agency's exposure and your exposure are not the same thing.

When cloaking is detected, enforcement does not stop at a single ad account. It can reach the connected business assets: pages, pixels, domains, and in some cases the personal profiles administering them. The agency loses an account from a pool it expected to lose. You can lose the brand's presence on the platform, along with the audience data you have accumulated.

Separately, and regardless of what any platform does, the regulatory exposure of selling research-use-only compounds sits with the seller. The FDA and FTC do not send letters to your media buyer. If aggressive ad copy crosses into human-use or health-claim territory, it is your company on the envelope, and that same copy is discoverable evidence about how you market.

Strip away the deck and the proposition is this: pay a monthly fee to attach your brand and your legal exposure to cloaked ads running on somebody else's rented accounts. The upside is shared. The downside is not.

Then I ran the numbers

Set the platform risk aside entirely for a moment, because the economics did not work either, and that is a more useful lesson for most operators reading this.

At the suggested minimum, the all-in monthly cost looks like this:

• $5,000 retainer
• plus roughly $3,040 of media at $100 per day
• plus 5% of spend, about $150
• = roughly $8,200 per month

Of that, about $5,150 is fees managing about $3,040 of actual media. That fee-to-media ratio is not inherently outrageous, but it only makes sense for a brand spending $30,000 a month or more, where the retainer is a small percentage of the budget it manages. We are not there.

Now take the case study at face value, which is generous given it was unverified. At a $61 acquisition cost, $3,040 of media buys about 50 customers. But I am not spending $3,040. I am spending $8,200.

My true all-in acquisition cost is about $164 per customer. Our existing channels acquire in the $45 to $60 range.

At roughly $210 of contribution per order, I would need close to 40 incremental new customers every month just to reach break-even. That is more than our entire current monthly new-customer rate. The program has to roughly double the business before I keep a single dollar, and if the acquisition cost lands north of $100 on our catalog rather than $61, the loss is meaningful for a company our size.

That is the thesis, and it has nothing to do with the agency being good or bad at their job: a fixed retainer puts all of the performance risk on the advertiser at exactly the stage when the retainer is about the size of the entire monthly contribution. The agency gets paid the same whether the campaigns work or not.

What to ask before you pay anyone

If you are evaluating an offer like this, the answers to these either surface the risk or get deflected, and the deflection is itself the answer:

• Whose ad account and business manager do the campaigns run on? If yours, why not mine?
• Who owns the pixel, the dataset, and the domain used for tracking?
• If an account is banned, what happens to my pixel history and my page? Does any of it transfer?
• Is my personal profile or business page ever named as an admin or owner on anything you set up?
• Walk me through exactly what the ad reviewer sees compared with what the customer sees.
• What is your ban rate per account, and how often do you replace them?
• When an account goes down mid-campaign, who absorbs the in-flight spend?
• On a regulatory issue, do you carry any liability, or is all of it mine?
• Will you indemnify me in writing?
• The case-study screenshot: which client, what window, and can I speak to them?
• Can I reference-check three current clients in this category, including one who was banned?
• What is the minimum term, and what is the refund position if no campaign is ever approved?

When paid media does make sense here

I am not arguing that paid acquisition can never work in this category. I am arguing it did not work for a business my size under that structure. Two things change the answer:

• Scale. Once media spend is large enough that a retainer is a modest percentage of it, the fee stops swamping contribution and the arrangement can be rational.
• Structure. Performance-linked arrangements, or running buying in-house on your own accounts, move the risk to where the decisions are being made.

What has not changed is the platform position. If a campaign can only run by showing the reviewer a different page than the customer, that is not a growth channel. It is a loan against your brand's existence on that platform, and the repayment date is set by someone else.

In the meantime, the channels that actually compound in this category are the unglamorous ones: creators and affiliates who disclose properly, email and SMS to a list you own, content that answers the questions buyers are already searching, and a storefront that converts the traffic you have. None of them get banned on a Tuesday.
