The AB Labs coupon code SIGNUP15% gives you 15% off supplements, but there’s a catch: their main website is password-protected and you’ll actually be buying through their Etsy shop. I spent two weeks researching this UK-based brand founded in 2024, and here’s what you need to know before using that discount code.
Verified AB Labs Coupon Codes
Important note: AB Labs operates primarily through Etsy while their main site (ablabs.co.uk) remains in development. This means your shopping experience differs from typical supplement brands. You’re not ordering from a polished e-commerce site—you’re buying through a marketplace platform.
What Makes AB Labs Different (And What Raises Questions)
AB Labs launched in 2024 positioning themselves as a premium supplement brand focused on “precision and integrity.” They claim third-party testing for every product and partnerships with reputable laboratories. Their target audiences are health-conscious consumers and researchers needing precision-grade compounds.
Here’s what caught my attention: they emphasize USP-grade ingredients and detailed lab reports. USP (United States Pharmacopeia) grade means ingredients meet specific purity standards. This matters for supplements because the industry is largely unregulated—companies can claim whatever they want on labels.
However, I need to be transparent about what I couldn’t verify. While AB Labs states that “detailed lab reports are available for every product,” I couldn’t find these reports publicly posted on their Etsy shop. For a brand built on transparency, this is a notable gap. You may need to request lab reports directly from the seller.
Product Lineup and Pricing Breakdown
AB Labs specializes in nootropics, vitamin blends, and detox supplements. Here’s pricing with the SIGNUP15% coupon:
Methylene Blue 10mg Gummies (60 count): £24.99 → £21.24 (saves £3.75)
NMN 600mg Capsules: £19.99 → £16.99
Psionic Boost Nootropic: £34.99 → £29.74 (saves £5.25)
Liver Health Capsules: £29.99 → £25.49
Your biggest savings come from premium nootropics priced above £30. Methylene Blue dominates their product line—this compound has gained attention in biohacking communities for potential cognitive benefits. At £21.24 for 60 gummies, you’re paying £0.35 per 10mg dose. However, Methylene Blue research is still emerging and it’s not FDA-approved for daily supplement use.
What I Couldn’t Verify (And Why It Matters)
AB Labs makes strong claims about quality, but several things gave me pause during research.
Their website is password-protected and marked as “in development.” For a brand claiming to serve customers in over 20 countries and operating since 2024, this seems unusual. Most supplement companies prioritize having a functional website with product information, ingredient lists, and those promised lab reports.
The reliance on Etsy as their primary sales channel is also noteworthy. While Etsy is legitimate, it’s unconventional for a brand positioning itself as scientifically rigorous and serving professional researchers. Researchers typically source precision-grade compounds from suppliers with detailed documentation, batch numbers, and comprehensive certificates of analysis.
I searched for the “detailed lab reports” mentioned in their mission statement. On their Etsy listings, I found ingredient lists but not the third-party testing documentation that would verify purity and potency claims. This doesn’t mean the products are low quality, but it does mean you’re taking claims on trust rather than verified evidence.
Who Should Use the AB Labs Coupon Code
Consider AB Labs if you: Are comfortable buying supplements through Etsy, interested in trying methylene blue products, want UK-manufactured options, or willing to request lab reports directly from the seller.
Look elsewhere if you: Need immediately accessible third-party testing documentation, prefer established brands with track records, require precision compounds for actual research (not personal experimentation), or want comprehensive customer service infrastructure.
The 15% discount makes experimental purchases more affordable. If you’re curious about methylene blue or their nootropic blends, the coupon reduces your risk. But this is clearly a newer brand still building their infrastructure.
Comparing AB Labs to Established Brands
At £21.24 for Methylene Blue gummies with the coupon, AB Labs pricing falls within normal UK supplement range (£15-40 for specialty nootropics). However, established brands typically offer functional websites with full product information, publicly posted certificates of analysis, batch-specific testing results, clear return policies, and verified customer reviews over time.
AB Labs is building toward this, but they’re not there yet. You’re essentially early-adopting a brand still establishing credibility.
The Etsy Shopping Experience
Since you’ll purchase through Etsy, expect differences from typical supplement shopping. Etsy provides buyer protection and reviews, adding security. However, you won’t find detailed FAQs, ingredient sourcing information, or usage protocols that professional supplement brands typically provide. Questions require messaging the seller directly through Etsy.
How to Apply the AB Labs Coupon Code
Here’s the process for using your SIGNUP15% discount:
- Visit the AB Labs (note: this may redirect to their Etsy shop)
- Browse their product selection and add items to your cart
- At checkout, look for the “Add coupon code” or “Promo code” field
- Enter SIGNUP15% exactly as shown (including the percent symbol)
- Verify your total drops by 15% before completing payment
- Check confirmation email for shipping details
If the code doesn’t apply, try it without the percent symbol (just SIGNUP15) as different systems format coupon codes differently. Contact the seller through Etsy messaging if you encounter problems.
My Honest Assessment
AB Labs presents itself as a premium, scientifically-backed supplement brand, but the execution doesn’t fully match the positioning yet. The emphasis on USP-grade ingredients and third-party testing is exactly what the supplement industry needs. The problem is I couldn’t verify these claims through publicly available documentation.
For a brand founded in 2024, they’re still in early stages. The password-protected website and reliance on Etsy suggest they’re building infrastructure while selling products. This isn’t necessarily bad—many successful brands started small—but it does mean you’re buying based on claims rather than established reputation.
The SIGNUP15% coupon code makes experimentation more affordable. If you’re curious about their methylene blue products or nootropic formulas, the 15% discount reduces your financial risk. Just go in with realistic expectations. You’re supporting a newer brand, not buying from an established supplement company with years of verified testing and customer feedback.
Save 15% on Your First AB Labs Order
If you’ve decided to try AB Labs supplements, the SIGNUP15% coupon code provides legitimate savings. The discount works across their product line, making their premium nootropics slightly more accessible.
Shop AB Labs with the SIGNUP15% coupon code and explore their UK-manufactured supplement range. Just remember to request lab reports if third-party testing documentation is important to your purchasing decision.
Final advice: Start with one product rather than stocking up. Test their quality, customer service, and how well the supplements work for you before making larger purchases. The 15% coupon will likely still be available for future orders, and you’ll have better information to guide your decisions.
