That is funny how everyone 'smells'these comps differently.. test e gives me a headache if I smell it for too long.... tren as well... but the descriptions of the smells are not far off... I think tren has a 'garlic funk' to it that basically will smell up anything within a couple feet of the bag of it... It is probably one of the stongest smelling raws there is(and, I'm sure that's why your sweat smells funny when you are on it!).. I do like the smell of deca and npp, they both have a light, sweet smell to them...
OP, test e has a VERY low melting point! If it was warm at all, it almost looks like a big chunk of wax that is beginning to soften and melt along the outside of it(and it looks like wax melting in the oil(or solvents), whichever you dissolve it in...).. I've seen it come in some crazy shapes cause it melted in shipping.. it is conformed to whatever container it was in by the time you get it...
most of the shorter esters are either a powder or crystalline in structure(test prop is def a crystalline structure, and depending on the manufacturing process may look like salt crystals(or even bigger, like pieces of glass), or may be powdery consistency, but if you look at it close, it is little tiny crystals(I remember the old synovex-H... the way you had to slowly crystalize it out of solution(to remove the e2), it ended up a very fine powder, that was millions of tiny crystals... )... Most of the prop you will get as raws these days is larger crystals(it can look like a big bag of meth... I always feel strange making it when the raws are large crystals like that, cause it's like you are cooking down meth or something...lol)
