Another 30 mg
Reordered the 30 mg. Meals are still smaller and the box was on the porch the next evening.
Simple reorder
Checked out, it arrived, nothing crushed. I'll stay on the 10 mg.
Staying with it
Third order. Same vial, same result, shipping still quick.
Jeans fit easier
Belt is a notch looser. 20 mg arrived sealed and on time.
Less snack noise
I stopped opening the pantry between meals. Label matched the order. No leaks.
30 mg again
Went back to the 30 mg. Appetite is quiet and the shipment was here before the weekend.
Porch drop-off
Showed up when tracking said it would. I'm not thinking about food all afternoon.
Worth the reorder
Scale moved a little. Face looks less puffy. Packed well.
No tool needed on the cap
Cap came off cleanly. Under it, a normal stopper and an even crimp. 20 mg, COA matched, cake dry. Easy receive.
Plain shipper
No cold-pack theater, just a dry vial packed so it wasn't rattling. Seal unbroken. That's the right way to send lyophilized powder.
