Chihuahua puppy loves these!
Pattern Name: Strip, Size: 3 Ounce (Pack of 1)
My little 13-week-old, 2.4-lb Chihuahua pup loves these chews. They are the perfect size for her tiny mouth.
I hold them for her, and when enough gets chewed that it could break off and possibly cause a choking hazard, I cut that soft part off with the scissors.
-I would never give them to her unsupervised.
-Will purchase again.

I take 3 pills , sleep like a baby
Size: 240 Count (Pack of 1)
Melatonin works well for me as a sleep aid. I take 3 pills, and I usually fall asleep within about 30 minutes.
It helps me relax and fall asleep faster, especially on nights when my mind is active or I have trouble winding down. The effect feels gentle, not harsh.
It is helpful for occasional use, but I don’t rely on it every night.

Pretty good
Size: 240 Count (Pack of 1)
Pretty good, I like the taste but it can be a bit strong on the last bite. With the gummies I normally take one ten mg but with these I feel like I need two
