Started ordering from them in Oct 2024 (Jun 2026 as I write this). I've found them to be very professional. Orders have shipped immediately and arrived within two days. They've responded to emails I've sent. The only issue I've had was actually with my first order. The GLP-3 was cloudy. I emailed them and was sent a replacement product immediately. I've also double checked on their testing certifications -- sites show the product being tested and they were the seller.
