ice pack was warm
marcus742

Box showed up with the cold pack completely thawed and lukewarm. The summer heat probably didn't help but the packaging felt a bit thin for shipping anything temperature sensitive. Emailed them about it.

good price on retatrutide
alicia_r763

Their retatrutide was noticeably cheaper than the two other vendors I checked. Vials arrived intact and the fill looked consistent across all of them. Will probably reorder.

COA wasn't batch specific
christian597

Product itself seemed fine and shipping was about a week. My only gripe is the COA they sent looked like a generic one for the peptide, not tied to my actual lot number. Asked support and got a vague answer.

solid little source
Diane T.

Stumbled on Monarch through a forum post and figured I'd try them. Order was packed well and the vials looked clean with proper labels. Not a big name but no complaints here.

noticed a price bump
Carla Q.

Reordered tirzepatide and it had gone up since my last order a couple months back. Still shipped on time and arrived sealed, just a heads up on pricing.

plain packaging
Diane L.

It's fine. Box was about as basic as it gets and no frills, but the ipamorelin arrived sealed and the COA was in there.

good support
Rebecca R.

Had a question about my BPC-157 order and the rep got back to me same day, no hassle. Shipping took about a week.

decent but ice pack melted
Scott I.

Ice pack was fully thawed by the time my order arrived. Vials still sealed and looked fine, just wasn't sure what to make of it.

happy with it
Edward E.

GHK-Cu showed up well packed, COA matched the batch this time. Good little vendor, will use again.

ok experience

Order was correct and the vial fill looked right. Emailed a question and it took three days to get a reply though.

Solid combo stack, one hiccup
Willow Kemp

Ordered the CJC/Ipa blend and standalone Ipamorelin for my research protocol. Both came with COAs that checked out when I verified the batch numbers. Shipping took 6 days which was a bit longer than advertised but not terrible. The Ipamorelin vial had a small crack in the rubber stopper when it arrived - still usable but made me nervous. Customer service replaced it no questions asked within 48hrs. Quality seems legit based on reconstitution and clarity. Pricing is middle of the road. Would order again but hoping for better packaging next time.

out of stock a lot
Carl R.

Half the things I wanted were unavailable, including retatrutide. Ended up ordering just MK-677. It came fine but the stock situation is frustrating.

fair pricing
Ronald L.

Their CJC-1295 was a few dollars cheaper than the two other places I checked. Packaging was plain but everything was sealed properly.

shipping slower than expected
Samuel A.

Took about nine days for my TB-500 to land. Nothing wrong with the order when it arrived, just slower than I hoped from a domestic vendor.

Mixed feelings about this order
Griffin Stone

Got the CJC-1295/Ipamorelin combo after seeing good things online. The COA looked legitimate and purity numbers were decent at 98.3%. However the customer service experience was frustrating - took 3 days to get a response to a simple question about reconstitution volume. Shipping was actually pretty fast at 4 days. Product itself seems fine, dissolved clear with no particulates. My main gripe is the price point feels high for what you're getting compared to other vendors I've used. Not bad overall but not exceptional either. Probably won't be my go-to vendor moving forward.

quick and clean
Lisa R.

Tirzepatide shipped next day, lyophilized cake intact, no cracked stoppers. Reordering.

COA not batch specific
Lance N.

The semaglutide COA on the site was a generic one, not matched to my lot number. Product itself looked fine, powder reconstituted clear. Just wish the paperwork lined up.

solid small vendor
mark_notes

Ordered BPC-157 and ipamorelin, both turned up in five days with COAs tucked in the box. Vials sealed and labeled fine.
