Monarch Research

I went in with low expectations because Monarch is pretty obscure and I'd never heard anyone mention them. Ordered BPC-157 and TB-500, both came double bagged with a real cold pack and printed COAs in the box. Shipping was four days domestic with tracking that actually updated. Customer service answered a stock question within a couple hours. For a small operation this was a really clean experience and I'd recommend giving them a shot.

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

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