How to Choose a Peptide Marketing Agency

most agencies that pitch peptide brands are generalist ecom agencies wearing a lab coat. they can run meta ads. they cannot get you a merchant account that survives month three, they have never written a product page that a compliance reviewer would sign off on, and they have no relationship with a compounder or a private-label supplier. that gap is the entire reason peptide launches stall. so the right way to choose a peptide marketing agency is to test for the unglamorous parts first — payments, compliance, sourcing, fulfillment — and treat creative and media buying as table stakes.

this is written operator-to-operator. we run margin, so we obviously have a horse in this race. we've tried to make it useful anyway — the checklist below will help you disqualify us just as fast as it helps you disqualify anyone else. that's the point. a bad fit costs you six months, and six months is the whole game in this category.

what a peptide agency actually has to do

a normal dtc agency owns two things: ads and email. a peptide agency owns the whole chain, because in this category the chain breaks in places a normal brand never has to think about. before you evaluate anyone, get clear on the full scope of work so you know what you're buying and what you're keeping in-house.

• —compliance and claims: what your site can say, what it can't, how the product is described, medical oversight structure, telehealth relationship if you're going that route, disclaimers and terms.
• —payment processing: high-risk merchant accounts, backup processors, descriptor setup, chargeback thresholds, and what happens when a processor gets nervous.
• —sourcing and private label: supplier vetting, third-party testing and COAs, MOQs, packaging, labeling, lead times.
• —storefront and funnel: product pages, quiz or intake flow, subscription mechanics, upsells, checkout.
• —3PL and fulfillment: cold chain if required, kitting, shipping SLAs, returns.
• —paid acquisition: meta primarily, creative production, account structure, testing cadence, and the landing pages that carry the traffic.
• —retention: email and sms flows, refill cadence, reorder prompts, winback.

an agency that only owns line six is selling you a service. an agency that owns lines one through seven is selling you a launch. both are legitimate — but you should know which one you're paying for, and you should never pay launch prices for line six.

the eleven questions that separate real from resume

ask these on the first call. write down the answers. the specificity of the answer matters more than the answer itself — vagueness here is the tell.

1. 1.how many peptide or med spa brands have you personally taken from zero to live? not 'worked with' — launched. get a number.
2. 2.which payment processors have you placed clients on, and what happened to those accounts twelve months later? anyone who has done this more than twice has a story about an account going sideways. no story means no reps.
3. 3.walk me through how you'd structure my product pages for compliance. if the answer is 'we'll have your lawyer look at it,' they have no framework of their own.
4. 4.who are your sourcing relationships, and can you show me a COA from a batch you've handled?
5. 5.show me an ad account. not a case study deck — screen share the actual ads manager, with spend, purchases, and ROAS columns visible.
6. 6.what's your creative production volume per month, and who makes it? in-house editors, ugc creators, or are they reposting my content?
7. 7.what happens when an ad account gets restricted? what's the recovery process and who executes it?
8. 8.what does week one look like, day by day?
9. 9.who is actually on my account day to day, and what else are they running?
10. 10.what's the smallest client you have and the biggest? if you're the smallest by 5x, you'll get the junior. if you're the biggest by 5x, you're the experiment.
11. 11.what would make you turn down this engagement?

that last one is the sharpest question in the list. an agency with real standards has a list of deals they say no to — wrong margin structure, unrealistic timeline, founder who won't appear on camera, product they don't believe in. an agency that says 'we can work with anyone' is telling you they need the cash more than they need the result.

red flags, ranked by how much they'll cost you

• —guaranteed ROAS or guaranteed revenue. nobody can guarantee this. anyone who does is either lying or is going to spend your money recklessly to hit a number, then churn you.
• —no named processor path. 'we'll figure out payments' means a stripe account that dies in six weeks and a hold on your cash.
• —case studies with no spend numbers. a 12x ROAS on $900 of spend is noise. always ask for spend alongside return.
• —they want to start ads before the store, offer, and flows are built. this is the most common failure mode. traffic into a broken funnel just buys you expensive data.
• —twelve-month lock-in with a big upfront. three to six months is reasonable for a build. twelve months before you've seen anything is a financing arrangement, not a partnership.
• —the person who sold you is not the person who runs the account, and they won't tell you who does until after signing.
• —no opinion about your offer or your price. a good agency will push back on your pricing and packaging in the first call, because the offer determines whether any of the rest works.
• —they talk about impressions, reach, or engagement in a revenue conversation.

that number is a useful lens for evaluating creative capacity. winning in this category is a volume game — you need enough concurrent creative in market to find the two or three angles that carry the account. ask any agency what their live-ad count looks like on a scaling client. if it's twelve, they're not testing, they're maintaining.

pricing models, honestly explained

there are four common structures, and each one distorts incentives in a specific direction. know the distortion before you sign.

flat monthly retainer

typical range for a real peptide or med spa growth engagement is roughly $5k–$15k/month depending on scope and spend level. clean and predictable. the distortion: the agency gets paid the same whether you grow or not, so quality depends entirely on their standards and their churn anxiety. good for build-heavy phases where output isn't tied to revenue yet.

setup fee plus retainer

a one-time build fee (commonly $5k–$25k depending on how much of the stack they're constructing) covering compliance setup, payments, store, sourcing intros, 3PL, and initial creative — then a monthly for ongoing media and creative. this matches the actual shape of the work: launching is front-loaded, scaling is recurring. the distortion is minor, but make sure the setup fee has a defined deliverable list and a date attached, not just 'onboarding.'

percentage of ad spend

usually 10–20% of managed spend, often with a floor. aligns the agency with spending more, which is only aligned with you if the spend is profitable. if you use this model, put a performance floor on it: the percentage only applies while blended ROAS stays above an agreed number.

revenue share or performance-based

typically a reduced retainer plus 3–10% of net new revenue, or a tiered bonus above a baseline. this is the most aligned structure and the hardest to get right. the traps: what counts as 'attributable' revenue, whether returning customers count, and what happens on month one when there's no baseline. get the definition of the revenue base in writing with an example calculation. pure performance-only deals are rare and usually mean the agency is taking creative control and a much larger cut.

our take: for a launch, setup fee plus retainer is the honest structure, and a performance kicker on top is fine once there's a baseline to measure against. avoid any deal where you can't articulate what you're buying this month.

how to read a case study without fooling yourself

every agency deck has a big number on it. here's how to pressure-test one. ask for spend alongside return — a 14x on a $6k test budget and a 4.45x on $4.3M are very different achievements, and the second one is harder. ask for the time window. ask whether the number is platform-reported ROAS or blended (total revenue divided by total ad spend), because platform ROAS routinely overstates by 20–60% depending on attribution settings. ask what the brand's starting point was: an agency that took a $400k/year brand to $900k did more work than one that 10x'd a brand from $20k.

for reference, here's how we'd want you to read ours. livv well, a med spa, scaled over 1,200% in six months with top creatives running 6.79–14.96 ROAS across 294 live ads. wayyless: $4.3M in ad spend produced $19.1M in revenue at a 4.45 blended ROAS — that's the one we'd point at, because blended at that scale is the honest metric. ac-nextgen ran top creatives between 7.5 and 16 ROAS, including one ad that returned $53,269 on $6,049 in spend. goodscience had a single creative return $33,225 on $8,664. those are real accounts and real numbers. they are also not a promise about your business: results vary with offer, price point, market, margin structure, and how fast you can produce creative. anyone who tells you otherwise is selling.

what a good first 90 days looks like

you should be able to hold an agency to a shape, even if you can't hold them to a number. this is a reasonable shape for a peptide launch.

1. 1.days 1–14: compliance framework agreed, entity and medical structure confirmed, high-risk merchant application submitted with a backup, supplier selected and samples ordered, 3PL contracted, store built, first creative batch in production. live in under two weeks is achievable when the operator moves fast on approvals.
2. 2.days 15–45: ads live at a testing budget. you are buying data, not profit. expect volatility. the goal is finding two or three creative angles and a landing page that converts above 2%.
3. 3.days 46–90: scale the winners, kill everything else, build the email flows against real purchase behavior, and get a first read on repeat rate. this is where you decide whether the offer is real.

the agency that wins your account on the first call is usually the one that told you something you didn't want to hear about your offer.

the contract terms that actually matter

• —asset ownership: you own the ad account, the pixel, the domain, the store, the merchant account, the creative files, and the email list. all of it, in writing. an agency that runs ads from their own business manager on your behalf is holding your business hostage.
• —notice period: 30 days is standard, 60 is acceptable, 90 is a leash.
• —offboarding: define what handoff includes — account access transfer, creative files in editable format, flow documentation, supplier contacts.
• —scope definition: name the deliverables per month. 'creative' is not a deliverable. '20 net-new statics and 12 video edits per month' is.
• —spend authority: who can change budgets, and above what threshold do they need your sign-off?

none of this is legal advice — have your own counsel review any agreement, and get an actual healthcare attorney on the compliance side rather than relying on any agency's framework, ours included. what an agency should give you is an operating structure and the reps to know where the landmines are. what a lawyer gives you is the sign-off. they're different jobs.

the fit question nobody asks

the highest-variance input in a peptide launch isn't the agency. it's whether the operator is willing to move. the brands that scale are the ones whose founder answers approvals within hours, shows up on camera for creative, has real capital allocated to testing, and doesn't panic at week three when CAC is ugly. if you can't do those four things, no agency will fix it, and you'll spend $50k proving that. be honest with yourself before you go shopping.
