Indigo-3G can help women greatly with body composition, as much so as men.
I don’t know what exactly you mean by very low bodyfat, but let’s say 12%. You could mean lower still, but I don’t know. If 12%, then your goal lean body mass would be 114 lb.
Your present LBM, if your bodyfat is about 26%, is 85 lb.
That would be almost a 30 lb gain, and even more crucially, a 34% gain in LBM.
I personally have never seen a woman achieve this without anabolic steroids.
I would set a first-stage goal that’s definitely achievable. A great first step for you would be to achieve a recomp where still at 115, your bodyfat has dropped to a lower percentage, say 16%. This would be a 12 lb fat loss combined with 12 lb muscle gain. I’m not saying that’s as far as you could ever go, but as a Stage 1 in your journey, it would be pretty sweet.
