Nutra remains one of the most reliable and long-lasting verticals in affiliate marketing, consistently delivering strong profits when executed with the right strategy. In this case study, I’ll walk you through how a well-optimized campaign for a well-known male enhancement product in Malaysia generated $8,000 in net profit over six months using banners and native ads.Campaign Overview

Offer Details
The Hammer of Thor offer is a popular Nutra product with broad appeal in the male enhancement category. Under the COD model, users simply submit their contact details. A call center then confirms the order, and payment is collected upon delivery.
Initially, I received a $9.10 payout per confirmed sale, which was later increased to $10.50 after consistently delivering conversions. This is a good reminder that negotiating with your affiliate manager for a payout bump can significantly improve profitability.
While I tested multiple offers and GEOs, Malaysia stood out for this product due to its combination of demand, acceptance of COD, and relatively low competition compared to other Asian markets.
Creative Strategy
For each campaign, I deployed over 20 ad creatives. While many Nutra marketers rely heavily on explicit imagery, I took a mixed approach. My creatives included variations of attention-grabbing visuals sourced from spy tools, but I also tested non-adult, curiosity-driven images. Surprisingly, non-adult landing pages delivered around 15% of total sales.
The pre-landing and landing pages were primarily provided by the advertiser, which saved time and ensured compliance with the offer’s branding and funnel structure.
Initial Testing
I launched two separate ad campaigns:
- Banners – Size 300x250
- Native Ads – Multiple placements
To maximize the chance of converting leads into confirmed COD orders, I scheduled ads to run during the call center’s operating hours. I also excluded non-proxy traffic to prevent wasted impressions from outside my target GEO.
Optimization Process
After the first month, campaign data revealed that the majority of conversions came from Android devices using Chrome, spread across four major carriers. With this insight, I:
- Whitelisted the top-performing carriers
- Increased bids for high-converting ad placements
- Focused more on Android + Chrome targeting
- Prioritized premium sources such as xHamster with higher bids
This targeted approach helped stabilize conversion rates and maintain profitability over several months.
Results and Longevity
The campaigns ran for six months, gradually slowing down toward the end as the conversion rate dropped. During the most active period, the campaign was largely on autopilot, with only periodic creative refreshes and pre-lander swaps to maintain engagement.
By the end of the run, the campaign had generated $21,450 in revenue against $13,445 in ad spend, resulting in $8,005 profit at nearly 60% ROI.
Key Takeaways
- Leverage COD in the right GEO – Countries like Malaysia respond well to COD models, making them ideal for Nutra offers.
- Negotiate payouts – If you’re delivering steady conversions, ask for a bump. Even a small increase can have a big impact on ROI.
- Don’t rely solely on adult creatives – Testing curiosity-based or clean creatives can reach a wider audience and improve compliance.
- Optimize by device, browser, and carrier – Data-driven targeting ensures budget is focused on the highest-converting segments.
- Refresh creatives regularly – Even profitable campaigns experience creative fatigue; periodic updates help maintain performance.
This case study shows that with consistent optimization, strategic targeting, and a willingness to test beyond the obvious creative angles, Nutra offers can deliver strong profits for months on end.
