Question 1

How much does Retatrutide cost?

Accepted Answer

A 20mg Retatrutide vial is $205, which works out to $10.25 per mg. The email-signup rate is $174 (15% off). The price includes bacteriostatic water and container, a batch Certificate of Analysis, and tracked shipping.

Question 2

What is the price per mg of Retatrutide?

Accepted Answer

At the standard $205 vial price, Retatrutide is $10.25 per mg ($205 / 20mg). At the email-signup price of $174 it is $8.70 per mg, and with email signup plus pre-order pricing combined at 25% off, $154 is $7.70 per mg.

Question 3

What is included in the price?

Accepted Answer

Every vial price includes a research reference document for education, a batch Certificate of Analysis, and educational support. Your kit includes the vials and bacteriostatic water. Insulin syringes ship with your order to select delivery regions; where they can't ship, we send a same-day sourcing link. A printed reference guide ships with every order. We confirm exactly what is included with your order. There are no separate kit or handling fees.

Question 4

Is Retatrutide cheaper than branded GLP-1s like Wegovy?

Accepted Answer

Yes. Branded semaglutide such as Wegovy runs about $1,349 per month at US retail. A 20mg Retatrutide research vial is $205, so you are comparing the raw compound cost against a branded prescription package. Peptara sells research-grade material with a published Certificate of Analysis, not a branded drug.

Question 5

Do you provide a Certificate of Analysis?

Accepted Answer

Yes. Every batch ships with a third-party COA confirming 98%+ purity by HPLC, plus identity (LC-MS), sterility, endotoxin, and heavy-metal screening. You can view the published certificates on our COA page.

Question 6

Are there discounts on the vial price?

Accepted Answer

Email signup gets you 15% off, which brings a 20mg vial to $174. Email signup plus pre-order pricing combines to 25% off, which brings it to $154. Wholesale pricing applies to orders of 10 or more vials of the same compound.

Question 7

What does retatrutide cost per month?

Accepted Answer

It depends on the weekly amount a protocol uses, which is a clinician decision, not ours, so the honest answer is arithmetic. The published phase 2 trial studied weekly maintenance amounts of 1, 4, 8 and 12 mg (Jastreboff et al., 2023). To get a dollar figure, multiply the $10.25 per-mg price by the weekly milligrams a protocol uses: that is $41.00 a week at the 4mg amount and $123.00 a week at the 12mg amount. How long a vial lasts is a separate question, and this site does not work out how many vials a reader needs, because that would require picking a dose. This is price math, not a dose recommendation.

Question 8

Where can I buy retatrutide?

Accepted Answer

Retatrutide is investigational and is not sold in pharmacies, so it is available only as research-grade material from suppliers. Peptara Labs ships every 20mg vial with a third-party batch Certificate of Analysis confirming 98%+ purity, and our where-to-buy retatrutide guide explains how to verify any source before ordering.

Question 9

How is the retatrutide vial reconstituted, and is bacteriostatic water included?

Accepted Answer

Yes, bacteriostatic water and a container are included in the $205 price. Reconstitution itself is arithmetic: the volume of bacteriostatic water you add against the 20mg in the vial sets the concentration, and our reconstitution guide and calculator report the result in units rather than mL. For anything about how a compound is administered, speak with a licensed clinician.

Question 10

Is retatrutide better value than tirzepatide?

Accepted Answer

On raw price per mg, tirzepatide is lower: a 20mg tirzepatide vial works out to $4.60 per mg against $10.25 per mg for retatrutide. On trial-reported effect, retatrutide's published phase 2 reached up to about 24.2 percent mean body-weight reduction (Jastreboff et al., 2023) while tirzepatide's SURMOUNT-1 reached up to about 22.5 percent (Jastreboff et al., 2022). Those are separate trials, not a head-to-head, so which is better value depends on what you are comparing. Our retatrutide vs tirzepatide comparison breaks down both.
