I would say that variations in size height and mass as well as training history would account for a lot . But at 15 , a bench press of 200 lbs or even 150 would be a rare sight . I don ' t think that a normal human body at that age is developed enough to hit those numbers in general . Give it time . Patience is key . <| sep |> Any sedatives should mix fairly well I ' d advise against alcohol , though . Pretty much everyone and their mom uses xans nowadays , so try a milligram or so of alprazolam along with your edible . Alternatively you could use an opioidate , preferably a less potent one so you don ' t risk fucking dying , but they mix well with weed . If none of that sounds fun , I love mixing dph with weed , it gets a lot of hate here but at lower doses it ' s super interesting .
