### ★★★★☆ in stock when others werent

*Angela W. — Jul 25, 2026*

Half the domestic vendors I tried were sold out of tirzepatide 10mg. Rasa had it, shipped same day since I ordered before the cutoff. Solid.

### ★★☆☆☆ echeck hold was a pain

*Greta X. — Jul 13, 2026*

Paid by eCheck for my first order and there was a 5 to 7 day hold before anything shipped. Wasn't clearly flagged at checkout. Once it cleared it moved fine but that wait soured the experience.

### ★★★★★ they made it right

*Aaron Q. — Jul 1, 2026*

Had an order where one vial cracked in transit, packaging was honestly a little thin for glass. Emailed them photos and they put a replacement on priority shipping plus tossed in an extra. Did not expect that level of service from a research supplier and it turned me into a repeat customer.

### ★★★☆☆ 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.
