A few words on my 6-apdb experience.
Long come up for me like 2 hours to peak, very MDMA-esque, cold fingers, music sounded amazing, pupils a bit dilated(not as much as with MDMA), I took a 80mg booster 3-4 hour's in, feeling really good, tripping a wee bit and I'd classify it as pill tripping/MDA(never had it in its pure form), walked past a mirror and I was wearing sunglasses(new one on me), audio hallucinations were more common and interesting.
Looking forward to trying it at a gig.
Thumbs up from me (can I say that)
