The honest answer is that the discount is identical — all six are a flat 10% sitewide with no minimum purchase and no product exclusions, and none of them stack. So 'best' cannot mean 'biggest'. It means the one most likely to still work when you reach checkout, which is the one with the longest unbroken record of daily tests: HEALTHYLIFE10.
Growth Guys' discount codes are configured as individual-use. When one code is already attached to a cart, the store silently refuses to attach a second — the request returns without an error message, and the discount line simply does not change. We found this while building the daily test: an earlier version of our checker did not clear the previous coupon between tests, and every code after the first one appeared to be dead. It was not. The cart was rejecting the second coupon because the first was still on it. So there is no combination of codes that beats 10%, and any page telling you to stack two Growth Guys codes for 20% is describing something the store will not do.
Lab-report figures, sources and today’s coupon details are on the front page · every cart test, retained.
None of them is bigger. All six are exactly 10% off sitewide, confirmed by same-day cart tests. Any listing advertising a 15%, 20% or 25% CODE at growthguys.com is either expired or belongs to a different company with a similar name.
Not one that we have been able to make work in a real cart. We test daily and retain every result, including failures, in the public log.
