KLOW Stack: the complete research guide

KLOW Stack 80MG is the only strength of KLOW Stack we make: a 80mg vial of lyophilised powder at $190, or $2.38 per mg. GHK-Cu, BPC-157, TB-500 & KPV quad blend, synthesised and tested in our own Australian lab.
What is in a 80MG vial
A KLOW Stack 80MG vial contains 80mg — 80,000 micrograms — of lyophilised powder.
Reconstituted with 1ML of bacteriostatic water it gives 80mg/ML, so a 0.1ML draw holds 8mg. With 2ML that becomes 40mg/ML and 4mg per 0.1ML; with 3ML, 26.7mg/ML and 2.67mg. The powder is the same either way — the volume only changes the concentration.
Bacteriostatic water is sold separately. Pre-mixed vials and pen cartridges arrive reconstituted, so this arithmetic only applies to the plain vial.
How many draws a 80MG vial holds
A 80MG vial is 80,000 micrograms, so at 250mcg per draw it holds 320 draws, at 500mcg it holds 160, and at 1mg it holds 80. That count does not change with how much bacteriostatic water is added — the water sets the concentration, not the quantity.
At $190 the vial, that works out to $0.59 per 250mcg draw, $1.19 per 500mcg draw, or $2.38 per 1mg. Cost per draw is usually a more useful comparison than cost per vial, because it is the figure that survives a change of strength.
80MG on a 100-unit syringe
A standard U-100 insulin syringe holds 1ML in 100 marked units, so one unit is 0.01ML. Reconstitute this 80MG vial with 1ML and 250mcg sits at 0.31 units; with 2ML it is 0.63 units; with 3ML, 0.94 units.
For a 500mcg draw the same three volumes give 0.63, 1.25 and 1.88 units. Choosing the volume that puts a typical draw on a whole number rather than an awkward fraction removes a whole category of measuring error, which is the practical reason to do this arithmetic before mixing rather than after.
Plain, pre-mixed or pen cartridge
KLOW Stack 80MG is $190 as a plain lyophilised vial, and the same as a mixed vial or pen cartridge: we reconstitute it here at no extra cost, and it arrives as a solution.
The plain vial keeps longest, because a lyophilised peptide stored cold and dry outlasts the same peptide in solution by a wide margin. Pre-mixed suits anyone who would rather not handle the reconstitution step, and the cartridge suits a pen. Bacteriostatic water is sold separately and is only needed for the plain vial.
Buying KLOW Stack 80MG in Australia
KLOW Stack 80MG is $190. Sydney delivery is free on orders over $100, so a single 80MG vial clears that threshold on its own. Everywhere else in Australia is $15 express post, free on orders of $200 or more. Orders placed before the daily cut-off dispatch the same day from Sydney.
The peptide itself is synthesised and tested in our own lab in Blacktown, NSW — not imported in bulk and relabelled here, which is how most research peptides reach the Australian market. That matters for a practical reason rather than a patriotic one: an imported peptide has a longer chain between synthesis and vial, the testing that matters happened somewhere else if it happened at all, and the certificate is one the buyer cannot trace.
Every batch is confirmed by mass spectrometry, measured at ≥99% purity by HPLC and screened at 0 ppm heavy metals, and the batch number printed on the vial resolves to that batch's own certificate. Supplied for in-vitro and laboratory research only, to buyers aged 18 and over.
Storing a 80MG vial
Lyophilised and kept cold and dry, KLOW Stack is stable for long periods — far longer than the same peptide in solution, which is the reason it ships as a powder rather than a liquid. Mixing a vial early rather than when it is needed simply spends that shelf life for nothing.
Once reconstituted with bacteriostatic water and refrigerated away from light, the practical working window is measured in weeks. The benzyl alcohol in bacteriostatic water inhibits bacterial growth, which is what makes repeated draws over that period reasonable; sterile water offers no such protection and gives a vial that should be treated as single-use.
Freezing a reconstituted vial is not an improvement — freeze-thaw cycles denature peptides, and the preservative that protects a refrigerated vial does nothing for one that has been frozen and thawed. Wipe the stopper with alcohol before each entry and use a fresh needle every time.
What is KLOW Stack?
KLOW Stack is a research compound in our Skin & cosmetic range. GHK-Cu, BPC-157, TB-500 & KPV quad blend.
At OzPeptides, KLOW Stack is synthesised and tested in our own Australian lab and sold strictly for research and laboratory use.
Why Australian-made KLOW Stack matters
Much of the peptide stock sold in Australia is made overseas and relabelled. Every OzPeptides batch is made here and tested in-house: ≥99% HPLC purity, identity confirmed by mass spectrometry and 0 ppm heavy metals, with a batch-matched certificate of analysis.
Strengths and formats
KLOW Stack is available in 80MG. Each strength has its own page. Peptides are available as a vial, pre-mixed or in a pen cartridge; mixing is free, or $5 a vial while a sale is running.
How quality is verified
Every batch is tested in-house before release. Purity is measured by HPLC and must be at least 99%. Identity is confirmed by mass spectrometry so the compound matches the label. Every batch is screened for lead, mercury, arsenic and cadmium, with results of 0 ppm. The batch number on your vial links to its certificate of analysis.
Formats explained
The standard vial contains lyophilised (freeze-dried) powder and is the base price. Pre-mixed is prepared in our lab for convenience, and the cartridge is made for our reusable metal pen; both are free, or $5 a vial while a sale is running.
Delivery
Orders confirmed before 1PM AEST ship the same day. Sydney orders are hand-delivered by our team; everywhere else receives tracked express post for $15 (free on orders of $200 or more), in plain packaging.
Research use only
KLOW Stack is sold strictly for in-vitro research and laboratory use, to buyers aged 18 and over. It is not for human consumption and is not approved for therapeutic use in Australia.
