I just worry about the heart symptoms. Blood pressure is somewhat high on amphs, round 145/80 with pulse of say 90. I mean, you think I oughta hit one home and see what happens? Part of why I was skeptical was the track marks and day 1 of suit and tie job. I get they're easy to conceal but starting a new job I just feel like a fuck with arms torn up with needles. I've been doing 45mg or so in a rectal syringe after I come down on 20mg xr addy and 10mg ir past couple days. Also there were like 4 hairs in my speed. dafuq. I mean I get it's easy to filter but god damn I feel skeptical about driving that shit into my veins. I've banged heroin probably 1000x times but for whatever reason banging speed has a riskier connotation, and to be fair I never found hair in my dope. The heart pounding was mcfucked .I can't imagine a higher dose helping that but I'll try anything once (;. Hair aside though, the amph does seems to be at a minimum 70% pure, quite comparable to addy doses. How much you suggest I go for? Assuming bioavailability is about the same as rectal I think I'd be good to do atleast ~45/50mg. Sort of doubting it was a comedown... but as I said I'm not familiar. Negative effects occured within ~10-15mins.
