Hey I have an update. I've been using Periactin for about 3 weeks now almost a month. My weight has been up my highest 120 and my lowest was 100 pounds. While using periactin I gained 10 pounds in 3weeks. Height: 5'7 Weight: 110 My goal is 135. I'm thigh heavy most of my weight go to my thighs and azz. I'm totally fine with that. I take it once at night everyday some people take it twice a day even 3times but once is fine with me. I'm just posting this for people who are interested in gaining weight.
