Why PT-141 10MG specifically

PT-141 10MG is the only strength of PT-141 we make: a 10mg vial of lyophilised powder at $60, or $6.00 per mg. Bremelanotide melanocortin research, synthesised and tested in our own Australian lab.

What is in a 10MG vial

A PT-141 10MG vial contains 10mg — 10,000 micrograms — of lyophilised powder.

Reconstituted with 1ML of bacteriostatic water it gives 10mg/ML, so a 0.1ML draw holds 1mg. With 2ML that becomes 5mg/ML and 500mcg per 0.1ML; with 3ML, 3.33mg/ML and 333.3mcg. 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 10MG vial holds

A 10MG vial is 10,000 micrograms, so at 250mcg per draw it holds 40 draws, at 500mcg it holds 20, and at 1mg it holds 10. That count does not change with how much bacteriostatic water is added — the water sets the concentration, not the quantity.

At $60 the vial, that works out to $1.50 per 250mcg draw, $3 per 500mcg draw, or $6 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.

10MG 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 10MG vial with 1ML and 250mcg sits at 2.50 units; with 2ML it is 5 units; with 3ML, 7.50 units.

For a 500mcg draw the same three volumes give 5, 10 and 15 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

PT-141 10MG is $60 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 PT-141 10MG in Australia

PT-141 10MG is $60. Sydney delivery is free on orders over $100, so a single 10MG vial does not clear it alone — Sydney delivery on a $60 order is $10. 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 10MG vial

Lyophilised and kept cold and dry, PT-141 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 PT-141?

PT-141 is a research compound in our Sexual health & vitality range. Bremelanotide melanocortin research.

At OzPeptides, PT-141 is synthesised and tested in our own Australian lab and sold strictly for research and laboratory use.

Why Australian-made PT-141 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

PT-141 is available in 10MG. 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

PT-141 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.
