### ★★★☆☆ support went quiet after the sale

*Regina C. — Jun 22, 2026*

First order with Rasa was smooth, but when I emailed a follow-up question about a second order I never got a reply. Three messages, nothing back. The product itself showed up fine so it's not a disaster, but the silence after they have your money is frustrating and it's the main reason I'm only at three stars here.

### ★★★★☆ good prices on retatrutide

*Victor E. — Jun 11, 2026*

Their reta pricing beat the two other domestic places I checked. Shipped quick, packed okay. Would order again.

### ★★★☆☆ decent but i wish there was a real coa

*Daniel G. — Jun 3, 2026*

Product arrived sealed and the website was easy enough to order from. My main gripe is the testing situation, it's all in-house and there's no batch-specific third party sheet in the box. For domestic GLP-1 pricing it's competitive, just wish they were more transparent on that front.

### ★★☆☆☆ vials looked underfilled to me

*Connor G. — May 27, 2026*

The semaglutide vials came in fine but a couple of them were noticeably below the fill line compared to the others in the same box. Reached out and got a fairly generic answer about minimum concentration. Not what I expected for the price.

### ★★★★☆ fast shipping

*Vivian Q. — May 18, 2026*

Ordered the tirz on a Tuesday and it was at my door Friday. No complaints on speed.

### ★★★☆☆ would order again maybe

*Keith L. — May 7, 2026*

Tirzepatide came sealed and on time, no problems. Just wish their COAs were more detailed and stock was steadier.

### ★★★☆☆ plain packaging but fine

*Felicia Q. — Apr 12, 2026*

Nothing fancy, just a padded envelope, but the vials arrived intact and sealed. Shipping was reasonable. Average source.

### ★★★★☆ happy customer

*Brett U. — Mar 9, 2026*

Quick shipping, vials labeled and sealed, fair pricing. Has worked out well for me a few times now.

### ★★☆☆☆ price went up

*Kevin R. — Feb 21, 2026*

Reordered semaglutide and the price had jumped noticeably from last time. Product itself was sealed and fine, but not the deal it used to be.

### ★★★☆☆ out of stock a lot

*Lance U. — Feb 2, 2026*

Half the things I wanted were unavailable when I checked. What I did order arrived fine and well packed.

### ★★★★☆ good price on tirz

*Cole G. — Jan 19, 2026*

Best tirzepatide price I found at the time and the order showed up quick. Vials sealed properly. Happy with it.

### ★★★☆☆ ok experience

*Holly Z. — Jan 4, 2026*

Retatrutide arrived in good shape, packaging was fine. Took about six days which is a bit slow for domestic.

### ★☆☆☆☆ COA mismatch

*Brian F. — Dec 18, 2025*

The certificate I got didn't match the lot on my vial at all. Support brushed it off when I asked. Won't reorder.

### ★★★★☆ no issues

*Marcus G. — Dec 6, 2025*

Third order with Rasa. Shipping is consistent and the vials always show up sealed and intact. Reliable enough.

### ★★★☆☆ decent value

*Mary X. — Nov 28, 2025*

Pricing is the main draw. Semaglutide came sealed and on time. Just wish they posted batch specific testing.

### ★★☆☆☆ slow to respond

*Karen I. — Nov 15, 2025*

Had a question before ordering and it took four days to hear back. Eventually placed the order and it was fine, but the support side needs work.

### ★★★★☆ quick turnaround

*Brandon H. — Nov 3, 2025*

Shipped within a day of payment and showed up fast. Tirzepatide vials labeled clearly. Would order again.

### ★★★★☆ Great selection for melanocortin research

*Leo Hartman — Oct 28, 2025*

Rasa Research has become my preferred vendor for both Melanotan II and CJC-1295. We're running comparative studies on melanocortin receptor agonists and need reliable sourcing for multiple peptides. Their catalog is extensive and well-organized, which makes ordering straightforward. Both peptides arrived within a week with comprehensive third-party COAs showing >98% purity. What impressed me most was the technical data sheets they include—detailed information on storage conditions, reconstitution protocols, and stability data that many vendors don't bother providing. Their customer service team is responsive and knowledgeable. I had a question about the difference between CJC-1295 with and without DAC, and their rep gave me a thorough explanation with citations. Packaging is excellent with vacuum-sealed vials and cold packs. Prices are reasonable, not the cheapest but fair for the quality. My only minor complaint is that their website checkout process is a bit clunky. Overall, solid vendor for serious research applications.

### ★★★☆☆ mixed feelings

*nicole\_coach — Oct 19, 2025*

First retatrutide order was great, second one the powder reconstituted a little cloudy. Hard to say if it was a one off.

### ★★★☆☆ Semaglutide quality issues

*Ruby Anderson — Oct 9, 2025*

Ordered Semaglutide for metabolic studies and the vial arrived with visible particles floating in the solution. Reached out to Rasa and they eventually sent a replacement, but it took almost two weeks. Replacement tested fine, but the initial quality control issue is concerning for a premium-priced vendor.
