The measured cart, line by line.
Searches for a Growth Guys 20%, 25% or 30% code are asking one thing: what is the largest reduction that actually applies at checkout. As of September 25, 2026 the answer is 30%, and it is not a code by itself.
Growth Guys applies 20% off automatically to orders paid with Bitcoin. HEALTHYLIFE10 applies in the coupon field on top of that. Both lines sit on the same cart, computed on the same subtotal, so they add: on September 25, 2026 a $430.00 CAD cart carried $86.00 CAD and $43.00 CAD — $301.00 CAD to pay. Pay by card and the ceiling is the 10% the code gives; there is no code that reaches 30% on its own.
Two codes on one order: the store accepts one coupon and silently ignores the second. A code on top of a catalogue sale: that compounds rather than adds, so 20% then 10% lands at 28%, not 30%. Codes advertised at 20, 25 or 35% on aggregator pages: those are generated listings, and across every guest cart in this site’s record the only rate a code has ever returned is 10%.
It is not a coupon. The store attaches it as its own discount line when the payment method is set, which is why it does not collide with the one-coupon rule and why the arithmetic is addition rather than compounding. That is also why it can disappear without warning: it is a payment-method promotion, not a code with a record behind it. This page is rebuilt from a live cart every day and says so the day it stops.
The full cart, line by line, with the raw store response: the Bitcoin record. Every HEALTHYLIFE10 test since the record began: the ledger.
Lab-report figures, sources and today’s coupon details are on the front page · every cart test, retained.
Not as a single code. 30% off is reached by paying with Bitcoin, which the store discounts 20% automatically, and applying HEALTHYLIFE10 for a further 10%. Measured September 25, 2026: a $430.00 CAD cart paid $301.00 CAD.
30% off, on September 25, 2026, by combining the automatic 20% Bitcoin payment discount with HEALTHYLIFE10. Paying by card the maximum is 10%.
No code returns 20% on its own; every code in this site's record returns exactly 10%. Paying with Bitcoin and applying HEALTHYLIFE10 exceeds it, at 30%.
