Growth Guys promo code, verified October 11, 2026: HEALTHYLIFE10 takes 10% off sitewide at Growth Guys (growthguys.com) on any payment method, and it is the code behind the largest total discount available there today — 30% off when the order is paid with Bitcoin, which the store discounts a further 20% automatically, so a $430.00 CAD cart paid $301.00 CAD. The measured cart, line by line.

Growth Guys BAC water — last verified at checkout at Growth Guys (growthguys.com): October 11, 2026 (today), 15:31 ET — HEALTHYLIFE10 applied and working, taking $4.00 CAD off a $40.00 CAD cart, exactly 10% off sitewide, with no minimum purchase and no product exclusions, including HGH kits; 2 live-cart checks so far today.
Autocomplete demand with no page of ours. Explains that the code is sitewide and applies to ancillaries too, which is the specific thing buyers assume is excluded — and our cart tests span $5 to $430 precisely to prove it holds at both ends.

One cart per line, all from October 7, 2026. The subtotals are not the same on purpose — if the code only applied below some threshold, a fixed-value test would never show it. Nothing was bought; the figures are read off the guest cart before checkout.
Enter HEALTHYLIFE10 where the cart asks for a discount code and make sure the figure changes before continuing. Guest carts are fine, no account is needed, and the code is not spent by using it once.
Not from the vendor's marketing. 244 test reports are published through Janoshik Analytical and each one opens on the lab's own site, which is what separates a testing claim from testing evidence. Across the 181 reports stating a purity figure the mean is 99.03%, the lowest kept on record is 93.844% and the highest 99.99%, spread over 133 products. Canadian stock, Canadian dollars, public vendor threads since 2021. The whole set.
Bacteriostatic water is sterile water carrying a small amount of preservative, used to reconstitute lyophilized compounds. The preservative is the entire point of the category: it is what allows a vial to be entered more than once rather than being a single-use diluent. At Growth Guys it is a 30 mL vial of Pfizer product at $25.00 CAD, sold separately from everything else.
Separately is not an upsell quirk. Every HGH and peptide in the catalogue ships lyophilized — a dried powder — and arrives unusable without a diluent. If you order compounds and no bacteriostatic water, you have ordered something you cannot put into solution. It is the one item people leave out of a first order and then wait another delivery cycle for.
The listing notes that supply shortages mean orders may be fulfilled with Hospira-branded bacteriostatic water instead. Hospira is owned by Pfizer, and the product is the same thing branded differently for the United States and Canada. Receiving a Hospira label is not a substitution with a different manufacturer's product.
This is worth stating plainly because a label that does not match the product page is exactly the kind of thing that reads as a red flag when it is disclosed nowhere and as ordinary supply management when it is disclosed in advance. Here it is disclosed in advance, on the product page, before purchase.
The volume you add determines concentration, and the concentration determines what a given measurement on a syringe represents. The vendor publishes its own worked example for growth hormone: a vial reconstituted with 1.1 mL of bacteriostatic water yields a solution at 10 iu per mL, because those kit vials each contain 11 iu.
Scale from that rather than from habit. A 30 mL vial of diluent covers a great many single reconstitutions at that volume, which is why one bottle usually accompanies a multi-item order rather than one per compound. Work out your own figure from the stated vial content and the volume you intend to add, and write it down — the number that matters later is the concentration, not the volume you happened to use.
Bacteriostatic water is stored at room temperature, away from direct light, and does not require refrigeration. That is the opposite of the compounds it reconstitutes, which are refrigerated after reconstitution — so the two halves of the same order have different storage answers, and assuming one covers both is a common error.
It is also the single exception to the testing policy. The stated rule is that a product that is not lab tested is not sold, with pharmaceutical bacteriostatic water produced by Pfizer named as the one item outside it. That is a coherent exception rather than a gap: the argument for third-party assay is strongest where the manufacturer is unverifiable, and weakest for a pharmaceutical product from a named manufacturer. The vendor separately warns against off-brand or informally sourced bacteriostatic water, which is the same reasoning pointed the other way.
Quantity is set by how many vials you will reconstitute and at what volume, not by how many products you bought. Using the published growth hormone example of 1.1 mL per vial, a single 30 mL bottle covers a great many reconstitutions, which is why one bottle typically accompanies a multi-item order rather than one per compound.
Two things pull the other way. The preservative is what permits repeated entry of the same vial, but every entry is still an opportunity for contamination, so the number of entries is worth minimising rather than maximising. And a 30 mL bottle is $25.00 against compounds costing several times that, so running short to save a line item is a poor trade — particularly when the shortfall arrives as another delivery cycle rather than as an inconvenience.
Yes, as of October 10, 2026. A $100.00 CAD guest cart at growthguys.com lost $10.00 CAD when the code was applied, which is the full 10%. The page carries that test's date, not its own publication date.
Yes, for all HGH and peptides — they ship lyophilized and must be reconstituted before use. It is sold separately as a 30 mL Pfizer vial at $25.00 CAD, so it needs to be added to the order deliberately.
Hospira is owned by Pfizer and the product is identical, branded differently in the United States and Canada. The product page discloses that supply shortages may mean orders are fulfilled with Hospira-branded stock.
At room temperature, away from direct light; refrigeration is not required. Note that this differs from the compounds it reconstitutes, which must be refrigerated after reconstitution.
