If it's a female, I wouldn't classify it as an adult -
Since at 600 grams, females aren't sexually mature yet.
If it's a she, I'd say it's a "Sub-adult" since she would have a lot of growing to do.

we will see what gender is. at the moments the first think i must do is true temps to start feeding.
it's very nice bp but i think is tooo streess coz any time is ball and i can handling it correctly. i ried to give him mice but nothing. i will try in dusk!

I would let him settle into his new home for a week, or even better a few weeks, before trying to feed or hold him. They can be difficult eaters if they're overstressed and not fully comfortable in their surroundings.

I don;t think your little guy is an adult yet! Here's a pic of my adult male; he weights around 5 pounds.

ok i know this is off topic but oh OMG!!!! do most males get like almost that big because i read they only reach like 3-4 ft and well yours is just huge!!!

Ozone: yeah my bp reeses is pretty much the same size as yours right now and he just truned a year old on the 6th(supposedly according to the guy i got him from) and i still don't have a weight for him. so yeah i don't think your is an adult but a really nice bp none the less. good luck with him/her :)
