Retatrutide 10mg

At ThePeptide.ca, Retatrutide 10mg is $90 CAD — $9.00 per milligram. Two larger formats are also in stock: Retatrutide 20mg at $140 ($7.00/mg) and Retatrutide 30mg at $180 ($6.00/mg).

Shipping is free and tracked to every province and territory in Canada with no minimum order value, so there is no threshold to reach and no shipping charge added at checkout — the listed price is the delivered price before tax.

Per milligram, the 30 mg vial is the best value at $6.00/mg ($180), followed by the 20 mg at $7.00/mg ($140) and the 10 mg at $9.00/mg ($90). All three are in stock.

• Three 10 mg vials cost $270; one 30 mg vial costs $180 — a $90 saving.
• Two 10 mg vials cost $180; one 20 mg vial costs $140 — a $40 saving.

Our automatic volume discount does not change that ranking. It starts at three vials (10% at 3+, 15% at 5+, 20% at 10+), so a two-vial order gets no discount at all, and three 10 mg vials come to $243 after the 10% tier — still $63 more than a single 30 mg vial at $180. On the 30 mg format the discount stacks on top of an already lower per-milligram rate, so buying multiples of the 10 mg vial never catches up.

A single larger vial also keeps an entire study on one verified lot. Smaller vials suit researchers who prefer to hold sealed backups in cold storage, or who only need 10 mg. Each format carries a published, batch-specific certificate:

• 10 mg — lot RETA-0626-01, 99.68% by HPLC-UV, certificate from Testides in Toronto.
• 20 mg — lot CS-re20-0710, 99.643% (Janoshik ref #207689), and 30 mg — lot CS-re30-0718, 99.751% (Janoshik ref #210575). Both figures come from Janoshik Analytical on a blind test; our own Testides confirmation on those two lots is pending.

Retatrutide is commonly referenced in research involving incretin receptor signalling, receptor-binding mechanisms, and downstream metabolic pathway models. It is currently in Phase 3 clinical evaluation through Eli Lilly's TRIUMPH program (TRIUMPH-1 topline reported May 2026).

The triple-agonist mechanism activates three distinct metabolic receptor pathways — GIP, GLP-1 and glucagon — which researchers study for comparative receptor-signalling and downstream pathway activity in vitro. Semaglutide acts on one of those receptors and tirzepatide on two, which is why retatrutide is used as the reference compound in three-way comparative work.

Yes. This 10mg lot was independently tested by Testides (Toronto) using HPLC-UV for purity verification and mass spectrometry for molecular identity confirmation. Batch-specific Certificates of Analysis (COAs) are published on our Lab Results page, with the lot number printed on every vial so you can match the vial in your hand to its certificate.

• Purity: 99.68% (HPLC-UV 214nm)
• Identity: Mass spectrometry confirmed
• Lot: RETA-0626-01 · 11.88 mg · reported July 2, 2026
• Testing lab: Testides, Toronto, Canada

The 20mg and 30mg lots were tested by Janoshik Analytical, and both were run as a blind test — Janoshik was given three candidate compounds and not told which the sample was, and identified retatrutide from its own analysis, which is stronger evidence of identity than an assay run against a stated label. They are published under Janoshik ref #207689 and #210575, with our own Testides confirmation on both lots still pending.

Retatrutide is supplied as a lyophilized (freeze-dried) powder for maximum stability.

• Lyophilized (unopened): Store at -20°C long-term or 2-8°C short-term
• Light: Protect from direct light at all times

Shipping is free on every order, Canada-wide, with no minimum order value, and every parcel is tracked. All orders ship from British Columbia, Canada.

• Processing: Dispatched within 48 hours (Mon-Fri)
• Delivery: Typically 2-8 business days anywhere in Canada
• Tracking: A tracking number is emailed as soon as your order ships

All research compounds are packaged in temperature-stable, tamper-evident materials. Vials are individually wrapped in discreet, unbranded packaging.
