Retatrutide 10 mg starts at $84.00, 20 mg at $120.00 and 30 mg at $185.00. Tirzepatide 10 mg is $55.00. Two- and three-vial bundles lower the per-vial price, and the full table is on each product page.
Why the same compound varies so widely in price
Two costs sit underneath any figure you see quoted, and suppliers differ in how much of each they carry.
Synthesis
A 39-residue peptide is built stepwise, and every step is an opportunity for a truncated or modified sequence to survive into the final material. Pushing purity higher means more careful synthesis and more aggressive purification, and both cost money. Material made to a lower specification is genuinely cheaper to produce.
Analysis
Testing costs money per lot. A supplier that analyses one batch and then reuses that certificate for everything it ships afterwards has a real and permanent cost advantage over one that tests each batch. The saving is not imaginary — it is simply transferred to you, as uncertainty about which batch your figure actually describes.
What the price here includes
Each released lot is analysed and publishes its own Certificate of Analysis, stating the method, the purity result and the date of analysis for that lot. The lot number is printed on the vial label and on the carton, so the material stays identifiable after the packaging is gone, and it resolves to that certificate in the COA library.
That is the part of the price that is easy to cut and hard to notice missing. It is also the only part that tells you anything about the specific vial you were sent.
Reading a quoted price properly
Compare on per-vial cost after bundling, not headline price, and check whether the purity figure is attached to a lot number or floating free on a catalogue page. A number with no lot attached describes some batch, at some point, at that supplier. It may or may not be yours.
Common questions
- How much does retatrutide cost?
- In this catalogue, retatrutide 10 mg starts at $84.00, 20 mg at $120.00 and 30 mg at $185.00, with a lower per-vial price on two- and three-vial bundles. Tirzepatide 10 mg is $55.00. Prices are visible without an account.
- Why do prices differ so much between suppliers?
- Mostly because of what is and is not included. Synthesis at higher purity costs more, and independent per-lot analysis costs more again. A supplier that tests one batch and reuses that figure across every later batch has a real cost advantage — and you carry the difference as uncertainty about what is in your vial.
- Does a lower price mean lower purity?
- Not necessarily, and that is the problem: without a per-lot certificate you cannot tell. Price alone carries no information about the vial in front of you. A lot-specific Certificate of Analysis does.
- Is bulk cheaper?
- Per vial, yes. Two- and three-vial bundles lower the per-vial price, and the full table is shown on each product page so the per-vial figure is visible before you order rather than after.
