If you searched growth guys promo code first order, HEALTHYLIFE10 at growthguys.com is the answer: it applies on a first order exactly as it does on any other, with no new-customer restriction and no minimum.
Many stores' first-order codes work once, which is why people search "first order code" expecting a one-time deal. At Growth Guys the tested codes aren't gated to new customers at all. Here's what most first-time buyers get wrong — they hunt for a special new-buyer code when the public code already gives them the full 10% on order one.
Checkout accepts one discount code per order. Enter HEALTHYLIFE10 at the cart on the first order and on every order after it; it needs no signup and no account.
The codes shared in Canadian peptide subreddits for a first Growth Guys order are the same public ones on this page — there's no secret Reddit-only new-buyer code. Anyone posting a higher-rate "first order exclusive" is describing a code that won't survive checkout. More on that pattern: the Reddit code guide. Recent independent cart tests on a first order landed the same result — HEALTHYLIFE10 applying a flat 10% off both times:
