Protein Factory Promo Codes & Coupons February 2026

IMRAN5 likely isn't working because Protein Factory promo codes like this 10% off deal often expire after heavy use or have unlisted restrictions like minimum order totals, even if shown as "last used 2d ago." Common scenarios include cart items on sale (codes exclude discounted products) or one-time-use limits per account, triggering errors like "Invalid code - expired or not applicable."

1. Clear browser cookies/site data
2. Log out and log back in
3. Add $100+ eligible items (non-sale whey/protein)
4. Enter code in the "Promo Code" field at checkout
5. Hit Apply before payment

Codes deactivate fast at Protein Factory due to high redemption (e.g., 531 uses on similar 10% codes); avoid peak hours like weekends. Also note that codes are typically single-use per customer and won't work post-expiry even if shown as "recent."

Pro tip: Test codes in incognito mode first—Protein Factory tracks sessions strictly for abuse prevention.

Enter FASTER exactly (case-sensitive) in the "Promo Code" box at the final checkout step on proteinfactory.com, then click "Apply" to see the discount reflect before payment. This code aims for 10-20% off sitewide but succeeds most on orders over $50 with standard proteins.

Users often miss it by applying too early (pre-cart summary) or with incompatible items like bundles. Protein Factory's checkout is streamlined: Cart > Shipping > Promo field > Review.

1. Build cart with eligible items (e.g., unflavored whey)
2. Proceed to checkout
3. Paste FASTER in the dedicated field under order summary
4. Apply the code
5. Complete your purchase

Works best mid-week; restrictions include no stacking and sale item exclusions.

Pro tip: Copy-paste from verified sites—manual typing fails 20% of the time due to Protein Factory's strict validation.

This error means WASILTAI10 (a 10% off code) doesn't apply to your specific cart items, often because they include on-sale products, bundles, or minimum thresholds aren't met (e.g., under $100). It's a common Protein Factory safeguard, blocking discounts on promo-priced whey or custom mixes.

1. Review cart for sale tags (red % off)
2. Remove sale items
3. Add full-price items to hit $100+
4. Re-enter WASILTAI10 at checkout's promo field

Codes typically exclude "featured deals" or third-party brands, and the error appears after clicking the Apply button. Also note that codes are valid only on new carts and clear after 24h session timeout.

Pro tip: Swap sale items for regulars like Mass Factory gainer—Protein Factory prioritizes full-price eligibility for codes.

No, you cannot stack OWEN5 (5% off code) with the refer-a-friend 6% discount—Protein Factory policies explicitly prohibit combining promo codes with other offers like referrals. Users report checkout errors like "One discount per order" when trying, due to their single-promo system.

When you enter OWEN5 first (which applies), then use a referral link—the system voids both.

1. Choose one discount method (OWEN5 for broader savings on $200+ carts)
2. Apply at checkout promo field
3. Note that referrals auto-apply via unique link pre-checkout but block codes

The refer-a-friend program offers 6% lifetime per referral, but it's non-stackable sitewide.

Pro tip: Prioritize the higher percentage discount (OWEN5 if >6%) on big orders—Protein Factory's no-stack rule saves them margins, but you can test options via guest checkout.
