Buy Retatrutide and Tirzepatide, the Incretin Receptor Agonists
Buy the incretin compounds by receptor count, the clearest way to separate the two at the centre of this range. Tirzepatide activates two, the GIP and GLP-1 receptors. Retatrutide engages the same pair and brings in the glucagon receptor as a third target, so it is classed as a triple agonist and is the usual choice when a study tracks energy expenditure or liver fat as well as appetite signalling. Tirzepatide has the longer published record, so many labs run it as the reference arm and retatrutide as the newer comparator, and it is often named the best GLP-1 peptide for a benchmark arm.
Order retatrutide in 10 mg, 20 mg and 30 mg vials at $129, $209 and $289, so a lab can match the fill to the length of a project rather than mixing more than it will use within 28 days of reconstitution. Tirzepatide is a 2 mg vial at $59, a small fill suited to pilot work. Both also come ready in solution, as the retatrutide pen holding 10 mg in 3 mL and the tirzepatide pen, a 3 mL multi-dose pen, each at $149 with no reconstitution step at all. Buy a pen when the study needs a ready solution from day one, and a vial when it needs a custom concentration. For a first order, the Retatrutide Starter Kit puts a vial, 3 mL of bacteriostatic water and a sterile syringe in one carton, from $134.
Shop Amylin, Growth Hormone Fragment and Energy Pathway Compounds
Shop cagrilintide as 5 mg ($69) and 10 mg ($119) vials. It is an amylin analogue engineered for a long half-life, amylin being the satiety hormone released with insulin, and it is often studied next to a GLP-1 agonist because the two pathways do not overlap. AOD-9604 takes a different route. It is a modified piece of the human growth hormone sequence spanning residues 176 to 191, examined in fat metabolism models without the IGF-1 activity of the full hormone, and it comes in 5 mg ($59) and 10 mg ($99) fills.
Order the five remaining entries when the study looks at energy use inside the cell rather than gut hormone receptors. 5-Amino-1MQ is a small molecule that inhibits the enzyme NNMT in fat cell research, sold as a 50 mg vial for $79. SLU-PP-332, also a small molecule, activates the estrogen-related receptors tied to mitochondrial biogenesis and is offered as a 5 mg vial or 60 capsules. MOTS-C is a 16 residue peptide encoded in mitochondrial DNA and studied for AMPK signalling. NAD+ is the coenzyme behind cellular energy transfer, and SS-31 binds cardiolipin in the inner mitochondrial membrane. All five are also listed with our mitochondrial compounds. Shop them here when an energy pathway arm sits beside an incretin arm, so the whole design can be checked out in one cart and traced to one set of certificates.
Order the Best Peptides for Weight Loss Australia Labs Study, by Pathway
Order by the pathway your study measures. For dual GIP and GLP-1 receptor work with a well documented comparator, choose tirzepatide. For triple agonism that includes the glucagon receptor, choose retatrutide. For amylin signalling, or a second arm beside an incretin agonist, cagrilintide fits. For fat metabolism outside the incretin system, look at AOD-9604 or 5-Amino-1MQ, and for mitochondrial energy output, MOTS-C, SS-31, NAD+ or SLU-PP-332.
There is no single best fat burning peptide on this page, and the right vial is the one whose mechanism matches the readout in an animal or cell model. Buy bacteriostatic water and a U-100 syringe alongside the freeze-dried fills, since most need both before use, while the two pens arrive ready to go.
Buy Metabolic Peptides Online in Australia
Buy with proof of identity first, because incretin agonists are among the most imitated research compounds on the market. Each AminoBlend lot is sent to an independent laboratory for mass spectrometry, which confirms the molecule, and HPLC, which reports purity. The lot number printed on the vial or pen leads to its report in our COA library, so the certificate can be read before an order is placed. Anything ordered and paid for before 3pm on a business day leaves the same day with tracked delivery across Australia.
Everything in this category is sold for laboratory and in vitro research only. Retatrutide and cagrilintide remain investigational, research grade tirzepatide is not the registered pharmacy medicine, and nothing here is approved by the TGA. We offer no guidance on administration or protocols outside the laboratory.

Metabolic Peptides FAQ
What are the best peptides for weight loss research?
It depends on the pathway being studied. Retatrutide is the triple agonist of GIP, GLP-1 and glucagon receptors, tirzepatide is the dual GIP and GLP-1 comparator, and cagrilintide covers amylin signalling. Buy retatrutide from $129 for 10 mg and tirzepatide at $59 for 2 mg, strictly as laboratory reagents that are not TGA approved or sold for use in people.
How does retatrutide differ from tirzepatide?
Retatrutide acts on three receptors and tirzepatide on two. Both activate the GIP and GLP-1 receptors, but retatrutide also engages the glucagon receptor, which is why it is chosen for energy expenditure and liver fat models. Tirzepatide has the longer published record and often serves as the reference compound. Our retatrutide vs tirzepatide guide compares them in detail.
Should I buy a retatrutide vial or the retatrutide pen?
Order the vial if you want control over concentration and the longest shelf life as dry powder, and buy the pen for a ready-made solution with no mixing. Vials cost $129, $209 and $289 for 10, 20 and 30 mg, while the 10 mg pen in 3 mL is $149. The starter kit adds water and a syringe to a vial from $134.
Is 5-Amino-1MQ a peptide?
No, 5-Amino-1MQ is a small molecule, not a peptide. It inhibits the enzyme nicotinamide N-methyltransferase, NNMT, and is studied in fat cell and energy metabolism models, so it sits beside the metabolic peptides. AminoBlend supplies it as a 50 mg research vial for $79, independently tested and matched to a lot certificate, for laboratory use only.
Are AminoBlend metabolic peptides lab tested?
Yes, an independent laboratory checks every lot before release, using mass spectrometry for identity and HPLC for purity, and the lot number on each vial, pen or kit matches a certificate you can open in our COA library. Anything paid for by 3pm on a business day leaves our Australian stock that same day.
