Is another IMG progression log allowed? 
I’m just so impressed at how fast she’s changing! And hopefully it helps someone out there looking at getting an IMG boa morph combo.
This is Sesame bun, an IMG RLT 66% het Anery. I understand Anery is recessive, but could 1 copy of the gene cause them to get darker faster even if they’re not visual anery? I didn’t expect her to be this black already not being a motley.

That’s fast! Beautiful boa.
If it was up to me half the forum would be full of boa pictures so of course it’s allowed!! Very pretty snake!!
Right! Can’t believe we’ve had her for 4 months already 
Hahaha yay! My phone is full of snake pics, happy to share as she grows
absolutely beautiful progression!
I can’t believe that’s just 4 months of growth, she’s going to be a stunner as an adult.
Boas change with size, and she’s grown a tooon for only 4 months so she’ll change a lot faster than a slower growing boa. I usually see that kind of growth in over a year. But she’s also surprisingly thin. She reminds me a lot of my RC hypo jungle boy, he also grows extremely rapidly and just refuses to have any sort of muscle tone. I started feeding him 4x as much as my other boas and he seems to slowly be gaining muscle. I just can’t believe he needs so much food, it took me forever to get around to feeding him more because literally none of my other 40 boas need that much or grow as fast as him. 
He’s been eating 20%+ of his weight weekly for months and there is finally a noticeable weight gain, but he’s still not built like what I’m used to. Here are old pics (since I’m on my laptop) for reference.
That’s very interesting to hear that someone else experienced this. Not sure if your boy started out like this too but my girl came to me very tiny and skinny looking, the breeder said she was a year old but she looked only a few months old at most and fit in the palm of my hand. I thought she had a medical issue because she just wasn’t growing. However like you said, I tried feeding her a little more frequently and adjusting based off her response/body condition rather than a standard fixed regimen. Even now, she’s still quite slender with prominent spine and not nearly as muscular as my other snakes but she does seem to be catching up. They must be like people, some people just need a lot more food and burn it all off, there’s not one diet that works for everybody. Is your guy grown up now? Did he end up a normal size?
No, he came to me a month old, and a good size for his age. He looked fairly normal at the time, it wasn’t until as he grew and wasn’t gaining muscle that I started wondering what was going on. But looking back he still had that look to him. Lemme post some more pics in a reply. I wasn’t offering him as much as I am now, because it just didn’t seem plausible he needed it. I have a few others with elevated feeding needs but nothing like him. He’s still not got great muscle mass even now, but I hope he’s getting there.
No, he’s not fully grown now, he’s maybe 4’-4.5’ atm, still growing rapidly. He’s a 2022. I was worried for a bit it was parasites or something, but he wouldn’t be growing and gaining weight if that was the case.
This was the day I got him, must have been his second shed ever since he was less than 30 days old.
These were the most recent pics I took, back in March, so I need to snap more once he’s out of shed. 6 months between these and the ones I posted above, about time for me to bump him to 150-200 gram rats I think, see how he handles that before I try up to 250 grams. I know the % to girth proportion closes as they get bigger. So while I was comfortable feeding 100-150 grams in the previous photos, I am not quite so sure 250 is good now.
He handles like a wet noodle. Floppy and empty. But when I took these pics, he was able to hold himself a lot stronger.
Wow he is huge compared to mine at all timepoints! Like 2-3x the size of my girl at least. Similar lean build. I can totally relate about the floppy noodle haha. For a while she had to use her chin to pull herself around because she didn’t seem to be able to crawl. She would also fall off stuff from not grabbing on strong enough. My little special needs girl hahah. But she’s definitely able to give a good squeeze now! Personally I’m feeding her smaller meals but more frequently and that seems to be good for her. We are still at rat pups right now, moving onto weaned rats soon.
It’s possible my tiny hands could be throwing things off too. 
My iPhone 13 completely covers my hand from all directions, if I keep my fingers together you cannot see even a sliver of any part of my hand. Like half the size of an average person’s hand. Unfortunately I don’t have any weights from before he was almost a year old, but he was basically a normal baby boa size iirc. So 60-80 grams. And now he’s a lot older than your girl tbf. Lol He’s just under 4 years old in those more recent pics.
And oof. No he’s never been that bad! Just has a hard time lifting his body, and he sploots his sides since the muscles aren’t there to hold his boxy shape. Which has been getting better and he’s getting more muscular now.
Hey whichever way works! If you’re seeing improvement that’s the important part.
