decent vendor
Maxwell D.

Second order from Monarch and both times the vials were well filled and labeled clearly. Prices crept up a little since my first order but still reasonable. Packaging is plain but functional.

good price on retatrutide

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.

solid little source

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.

good support

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

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.

fair pricing

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

solid small vendor

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