About PROLON

ProLon offers a 5-day plant-based fasting-mimicking diet designed to promote cellular rejuvenation and metabolic health. It provides nourishment while signaling the body to enter a fasting state, targeting health-conscious individuals seeking longevity and weight management benefits.

Why isn't my PROLON code working?

  • Check the dates. Codes can end early, so check the expiry date shown on the offer.
  • Check the minimum spend. Many PROLON codes only work above a basket value.
  • Check what's in your basket. Sale items, gift cards and some brands are often excluded.
  • One code per order. Most shops, including PROLON, only accept one discount code at a time.
  • Type it exactly. Codes can be case-sensitive; use the copy button to avoid typos.
  • New customer only? Welcome codes usually work only on your first order and account.

Still not working? Let us know with the "Did it work?" buttons and we'll re-check it.

PROLON FAQs

Promo codes usually fail because of specific restrictions: they may have reached their expiration date, they might apply only to full-priced items (excluding clearance), or your cart hasn't hit the required minimum total. We recommend checking the fine print on the https://prolonfast.com checkout page or trying a different code from our list to find one that fits your current order.

No, PROLON usually limits you to one promo code per order. However, you can often apply a promo code to items already featured in a sale or clearance offer. This allows you to combine a manual code with an existing site offer for maximum savings.

Add your items to the cart and head to the checkout page. Look for a field labeled "Promo Code" or "Discount Code," paste your code there, and click "Apply" to see your updated total before paying.

Yes, every discount code has a specific expiration date. We recommend checking the expiration date listed on our website as well as the brand's official site to ensure you use the code before it ends.

At Fine Gap, we prioritize accuracy over quantity. Unlike automated sites, we manually verify our brand offers to ensure they actually work at checkout. We also check the official brand website as well to provide the most up-to-date expiration dates and terms, saving you time and frustration.
