Each line is an independent cart from October 7, 2026. The values move between runs because a code that works at $90 and not at $400 should be visible as such. Everything is read at the guest-cart stage — no order placed, no payment information entered.
Apply it before checkout: HEALTHYLIFE10 in the cart's discount field, confirm the new total, continue. A guest cart is enough — no sign-in, no account, and it stays valid for repeat orders rather than expiring after the first.
244 published lab reports. 133 distinct products covered. 99.03% average purity across the 181 reports that state one, spanning 93.844% to 99.99%. Every one of them is hosted by Janoshik Analytical rather than by the seller, which is what makes the figures checkable instead of quotable. Shipping is domestic Canadian, pricing CAD, and the vendor has answered in public threads since November 2021. Itemised here.
The working Growth Guys promo code is HEALTHYLIFE10. It applies 10% off sitewide at growthguys.com, with no minimum purchase and no product exclusions — including the most expensive items in the catalogue, which is where discounts in this category are usually quietly withdrawn.
Three further properties decide whether it is useful rather than merely real. It is reusable rather than single-use, so it is not consumed by a first order. It works on a guest cart, so no account is required to test it. And it is entered at the cart rather than at the payment step, which means you can confirm it before any card details are involved. No expiry date is published, which is a statement about what has been advertised rather than a promise that none exists.
A percentage is a claim; a cart is a result. Tested at growthguys.com on October 6, 2026, at deliberately different order values: a $50.00 CAD cart paid $45.00, a $70.00 cart paid $63.00, a $75.00 cart paid $67.50, a $100.00 cart paid $90.00, and a $280.00 cart paid $252.00.
Every one landed on exactly 10%. The spread matters more than any single figure in it: a discount that quietly weakened above a threshold, or applied only to certain product classes, would have shown up across a range from $50 to $280. The cart value is changed on every run for that reason, rather than re-testing the same comfortable number.
Add anything to the cart, then enter HEALTHYLIFE10 in the discount field at the cart stage. The cart recalculates immediately and a discount line appears equal to exactly one tenth of the subtotal. If that line is not there, nothing has been applied, and continuing further into the checkout will not apply it later.
That visible line is the whole check, and it takes about thirty seconds. It is also the reason the cart stage matters as a procedural detail: you are testing the code while the only thing at stake is a page refresh, rather than discovering the outcome after your payment details are already in.
The code is also the one behind the largest total reduction available at the store, which is reached by paying with Bitcoin. Measured on a live cart on October 6, 2026: a $430.00 CAD subtotal came to $309.60. The code took $43.00 first, then the store's 20% Bitcoin reduction applied to the $387.00 remaining, taking a further $77.40.
That is $129.00 off, or 30%. Both reductions are computed on the full subtotal rather than in sequence, which is why the total is the sum and not a smaller compounded figure. It is worth stating precisely, because a cart preview can show the compounded number while the completed order charges the additive one — and a page that publishes the preview rather than the finished order is wrong in a way nobody checks. Order 175089 settles it: a $169.50 subtotal discounted $50.85, 30.00% on every line.
A working code is a fact about the checkout, not about the product. A reliable discount at a seller with no independent testing is simply a cheaper route to an unverified compound, and in that situation the percentage is the least important number on the page.
The second question has its own answer here, and it is not the one most pages give. What matters is not how many certificates a seller displays but whether any of them can be checked: these resolve on the testing laboratory's own portal under its own reference, so a specific batch can be confirmed without relying on the seller's copy of the file. Take the batch code from the vial, open the report on the lab's domain, and confirm it matches before the discount enters the decision at all.
"Sitewide" is a claim worth testing at the level of product types rather than cart values, because that is where exclusions normally hide. The catalogue splits into peptides, human growth hormone and ancillaries, and the discount applies across all three — including growth hormone kits, which are the highest-priced items on the site and the usual first candidate for a carve-out.
It also applies to multi-vial pack pricing, which is a product price rather than a coupon and therefore does not compete with the code. Ten single vials of Retatrutide 10mg would be $900.00; the 10-pack is $720.00; with the code that cart comes to $648.00. The one item worth naming as genuinely outside the discount conversation is bacteriostatic water, which is required to reconstitute anything lyophilized and is bought as a separate line rather than bundled.
Yes — the October 17, 2026 test applied it to a $80.00 CAD cart and took $8.00 CAD off, which is exactly 10%. The date on this page moves only when a test passes, so it records the last confirmation rather than the day the page was written.
HEALTHYLIFE10, which applies 10% off sitewide at growthguys.com with no minimum purchase and no product exclusions. It is reusable, works on a guest cart without an account, and is entered at the cart stage rather than at payment.
Exactly 10%, flat across order values. Tested October 17, 2026: a $50.00 cart paid $45.00, $70.00 paid $63.00, $75.00 paid $67.50, $100.00 paid $90.00, and $280.00 paid $252.00.
30% in total, reached by using the code and paying with Bitcoin. Both reductions are computed on the full subtotal: on a $430.00 order that is $43.00 from the code and $86.00 from the Bitcoin line, $129.00 off, paying $301.00.
