01

Acquisition & paid media

Metrics and concepts that govern peptide paid advertising on Google, Meta, and TikTok.

ROAS

Return on ad spend
Revenue generated for every dollar spent on advertising. A 3× ROAS means $3 in revenue per $1 of ad spend. Most managed peptide brands run a 3–3.5× ROAS on cold paid acquisition; lower than typical ecommerce because peptide audiences research longer before converting. Peptide paid media →

MER

Marketing efficiency ratio
Total revenue ÷ total marketing spend (across all channels). MER is a blended, holistic version of ROAS that captures channel interplay — email lift on paid, organic ROAS halo, etc. Most healthy peptide brands target a 3.5–5× MER.

CAC

Customer acquisition cost
What it costs to acquire one paying peptide customer. CAC is calculated as total marketing spend ÷ new customers acquired in the same window. Healthy peptide brands keep CAC under 35% of first-order revenue.

CPM

Cost per mille
Cost per 1,000 ad impressions. Peptide CPMs run high — typically $25–$60 on Meta — because ad platform compliance limits audience targeting and creative inventory.

CPC

Cost per click
What you pay for each click on an ad. Peptide CPC varies widely — $1.50–$8 on Meta, $2–$15 on Google depending on keyword. High-intent peptide search terms like brand names sit at the high end.

CTR

Click-through rate
The percentage of ad impressions that resulted in a click. Above 1.5% is considered healthy on Meta for peptide brands; on Google search, branded CTR routinely exceeds 8%.

CVR

Conversion rate
The percentage of website visitors who complete a purchase. Peptide ecommerce conversion rates typically run 1.5–3.5% on cold paid traffic, higher than supplement averages because peptide buyers arrive with higher intent after extended research.

AOV

Average order value
Average dollar value of a single order. Peptide brands often have unusually high AOV — $150–$400 — because customers buy stacks and reorder cycles favor bulk purchase.

LTV

Lifetime value
Total revenue generated by a customer across their lifetime. Peptide LTV is often $800–$3,000+ because repeat-purchase cycles are short and stack expansion is common. LTV:CAC ratios above 3:1 indicate a healthy peptide business.

Attribution window

The look-back period in which a conversion is credited to an ad. Apple's iOS privacy changes shortened standard windows from 28 to 7 days, which understates true peptide marketing performance because peptide research cycles often exceed 7 days.

Lookalike audience

An advertising audience built from people who resemble your existing customers. For peptide brands, lookalikes built from high-LTV customer cohorts (rather than all purchasers) consistently outperform broad lookalikes.

Retargeting

Showing ads to people who already visited your site. Critical for peptide brands because peptide buyers research extensively — first-visit conversion is rare. Most peptide brands recover 20–35% of revenue through retargeting alone.

Cold traffic

Visitors who have never heard of your peptide brand before. Cold traffic is the most expensive but also the only sustainable engine of new-customer acquisition. Cold-traffic ROAS is the truest measure of marketing health.

Creative testing

The systematic process of testing new ad creative against a winning control. For peptide brands, creative is the single highest-leverage variable — small differences in messaging can move ROAS by 0.5–1.0× because ad compliance constraints prevent many traditional ecommerce hooks.
02

Email & retention

The flows, metrics, and concepts that govern peptide email marketing.

Deliverability

The percentage of sent emails that actually reach the inbox (rather than spam). Peptide brands face elevated deliverability risk because email service providers monitor for compliance signals. A sender score above 95 and inbox placement above 90% are healthy benchmarks. Peptide email marketing →

Open rate

Percentage of recipients who open an email. Healthy peptide brand open rates run 28–45% on campaigns and 50%+ on top-of-funnel automated flows. Apple Mail Privacy Protection inflates this number; the trend matters more than the absolute.

Click rate

Percentage of recipients who clicked any link in an email. The most reliable email engagement metric since Apple Mail Privacy Protection distorted open rates. Healthy peptide brand click rates run 2–6% on campaigns.

Reorder cycle

The typical interval between a peptide customer's purchases. Most peptide products have a 28–60 day reorder cycle. Calibrating email and SMS flows to this cycle is one of the highest-leverage retention moves available.

Welcome flow

Automated email sequence sent to new subscribers. For peptide brands, the welcome flow has to do double duty: convert the subscriber and educate them on product use. Strong welcome flows recover 25–40% of email-attributed first-purchase revenue.

Abandoned cart flow

Automated email sequence triggered when a visitor adds product to cart but doesn't check out. Among the highest-ROI emails any peptide brand sends. Best practice: 3 emails over 24 hours, with the second email addressing the specific compliance and shipping concerns peptide customers actually have.

Browse abandonment flow

Automated email sent to logged-in visitors who viewed product but didn't add to cart. Lower per-email recovery than abandoned cart but higher volume. Critical for high-research peptide buyers.

Win-back flow

Automated email sequence targeting customers who haven't purchased in 60–120 days. For peptide brands, win-back works best when calibrated to specific product reorder cycles rather than a single time-based trigger.

List segmentation

Dividing the email list into groups by behavior, purchase history, or attributes for targeted messaging. The single biggest lever in peptide email marketing — segmented campaigns consistently outperform broadcast sends by 3–5× in revenue per email.
03

Compliance & vertical-specific

Terms specific to peptide ecommerce, research-use-only marketing, and the regulatory landscape.

RUO

Research use only
A regulatory classification for products sold strictly for laboratory and scientific research rather than human consumption. Most peptide ecommerce brands sell under the RUO designation. RUO marketing requires specific compliance language across ads, site copy, and email — generalist agencies routinely get this wrong.

Ad platform compliance

The set of rules an ad platform (Google, Meta, TikTok) enforces about what peptide ads can show, claim, and target. Compliance violations result in ad disapprovals, account restrictions, or full account bans. Peptide ad compliance is a discipline of its own — most peptide ad accounts that get banned are running creatives that would have been fine in a generalist vertical.

Payment processor risk

Most consumer-grade payment processors (Stripe, PayPal, Square) classify peptide merchants as high-risk and will terminate accounts that exceed informal chargeback thresholds. Peptide brands typically work with a curated short list of high-risk processors that approve the vertical.

Chargeback rate

Percentage of transactions disputed and reversed by the customer's bank. Peptide brands face elevated chargeback risk because customers occasionally dispute on receipt or refund disputes. Industry benchmark for processor-safe brands is below 1%.

Restricted product policy

Ad platform policy categorizing peptides and research chemicals as restricted (allowed but with constraints) or prohibited (not allowed). Policies vary by region and change frequently — an active peptide marketing agency tracks this in real time.
04

Web & conversion

Terms covering peptide ecommerce site design, conversion optimization, and analytics.

CRO

Conversion rate optimization
The discipline of systematically improving the percentage of website visitors who buy. For peptide brands, the biggest CRO levers are PDP trust signals (third-party testing, certificates of analysis), reorder-cycle messaging, and frictionless checkout for high-AOV bulk purchases.

PDP

Product detail page
The page where a customer views and buys a specific peptide product. PDP conversion rate is the single most important on-site metric. For peptide brands, the PDP must answer compliance questions, technical specs, and dosing context within the buyer's research process.

Landing page

A standalone page built for a specific ad campaign or audience. For peptide brands, dedicated landing pages typically outperform PDPs on cold paid traffic by 30–60% because they can pre-qualify, educate, and address objections in a more controlled flow. Peptide web development →

A/B test

Showing two versions of a page or ad to similar traffic and measuring which performs better. Critical discipline; peptide marketing intuitions are often wrong because the vertical's audience behavior is unusual.

Core Web Vitals

Google's set of page-experience metrics: Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS). Now a ranking signal. Peptide ecommerce sites running heavy theme apps often fail CWV — an easy SEO win for most brands.
05

Strategy & analytics

Higher-level concepts for analyzing peptide marketing performance.

Blended ROAS

Total revenue ÷ total ad spend across all channels — without per-channel attribution. Less precise than per-channel ROAS but immune to attribution distortions from iOS privacy changes. Many peptide brands manage primarily by blended ROAS now.

Cohort analysis

Tracking groups of customers acquired in the same period over time. Critical for peptide brands because aggregate metrics can mask cohort-level deterioration. A healthy peptide brand sees each cohort's revenue per customer rise over time.

Retention rate

Percentage of customers who buy again within a defined window. For peptide brands, 90-day retention is usually the most meaningful window because it covers the typical reorder cycle plus a stack-expansion window.

Churn rate

Percentage of customers who stop buying within a defined window. For peptide brands, churn is harder to measure than in subscription businesses because purchase intervals are irregular; cohort decay curves are more meaningful than a single churn number.

North star metric

The single metric that, when improved, advances the entire business. For most peptide brands, the right north star is net new monthly customers acquired at or below target CAC — not raw revenue.

Funnel

The sequence of steps a peptide customer moves through from first ad impression to repeat purchase. Peptide funnels are unusually long — research-led — and instrumentation matters because the gap between view and purchase often spans multiple weeks.
