Price per mg
Aggregates of single-vial research-use listings. A price counts only if it was still shown on the seller's product page when we re-fetched it on 2 Oct 2026 (first recorded 7 Aug 2026). Prices are converted to price per mg so vial sizes compare fairly. Sizes with fewer than three sellers are not shown. Bulk powder, lab reagents, multi-vial packs and approved brand pens are excluded.

Worked example: cost per week
Arithmetic illustration only, not a recommended dose: at 2 mg per week from a 10 mg vial, at the median price per mg of $12.50, the peptide itself costs about $25.00 per week (2 × $12.50). Doses used in studies are on the dosage page.
Why prices vary
- Research-use products are unregulated, so a low price can mean less active peptide than the label says.
- Bigger vials usually cost less per mg, but only if the whole vial is used before it expires.
- Prices change often, which is why every figure here carries the date it was checked.

Across 152 single-vial research-use listings re-checked on 2 Oct 2026, the median price per mg ranges from $6.00 to $18.20 depending on vial size; larger vials cost less per mg. These are not prices for an approved drug, and we never link to sellers.
Where can I buy Retatrutide?
We don't link to or recommend sellers. Retatrutide is not an approved drug, and research-use products are not checked by the FDA for identity, purity or dose.
