@mary_woods Yaaassss badass women like this give me life.
I completely agree that women can become pretty muscular without steroids. However it is impossible to go from Julia Vins's 2011 build to her 2014 build without steroids.
Using the McDonald Model, you can see that in the first year of training, a female can gain 10-12 lbs of lean body mass. In the second year of training, a female can gain 5-6 lbs, and in the third year of training, 2-3 lbs. In total, that's about 20 lbs max.
Does she look like she's only put 20 lbs on, in between those two photos? Remember that muscle is a lot more dense than fat/bone is. I would personally guess 30-40 lbs.
I debated against posting this, since I don't want to get into a "steroid-shaming" argument here, I think she looks great. However, I also don't want others to have unrealistic expectations. Hard work and dedication can only go so far!
You seem really invested in believing that she did not need to take steroids to develop this kind of mass -- even after other women who do use steroids have piped up and given informed views.
It makes me wonder if you have some (probably subconscious) reason for wanting to believe that she didn't need to take steroids to look this way. No worries if that's not the case, I just thought I'd throw it out there in case it strikes a chord.
She's also not cut down to small levels of bodyfat. I'm willing to bet she has around 20+% on her body. That'd make her look bigger too. Plus we don't know how healthy her starting weight was. For all we know she could have been basically starving herself thing and actually rebounded from that.
