So you want to tone up and gain muscle in your lower body. So I would say this should be a slight bulk. I know you should never ask (lol) but what's your rough age? I suspect your goal calories are perfect, as it'd have you around a 200-300 calorie surplus.
Do you want to compete in bodybuilding? Or are youbjust looking to have a sexy physique? Or are you a model trying to optimize things for photo shoots? What's your goal?
Your supplements are fine to continue on anavar. Just a word of advice though: drop the BCAAs as they are pretty much worthless. You should get EAAs if you want an amino acid supplement, or use whey/whey isolate instead especially if you're using as a post workout protein bolus. If you're using as pre-workout then I'd say definitely forget the BCAAs and get EAAs instead. BCAAs alonrbhave been shown to prevent some muscle breakdown but really they are nearly worthless compared to a full spectrum amino acid mix.
Carbs are awesome. Most bodybuilders and lifters love carbs. I love carbs and I am very lean, so does my girlfriend. She doesnt use PEDs, but shes got a 6 pack and a big ol' booty and quads and she makes sourdough bread regularly and we eat the shit out of it lol. She lifts 4-5x per week on an upper lower schedule I made for her. Especially if you're lifting, carbs provide the energy you need to lift and put out power, and they fill your muscles with glycogen giving your muscles a more full look.
Overall I think your supplements are fine, idk if the carnitine will help a lot given that you eat enough meat. If you sre interest in supplement research examine.com is good and consumerlab.com is great. I have a consumerlab membership and the content they put out is incredible. They also do supplement and various product testing for purity and contaminants and stuff. It's really helpful when selecting a brand/product that you plan to put into your body.
You should consider adding Vitamin K2 (MK-7) to your supplements, without K2 you can't really make use of vitamin D3 very much.. K2 allows you to use the D3 to incorporate calcium into your bones. The Healthy Origins brand tested best from consumerlab and I have been using it for years.
Overall, I'd say just make sure you read other women's anecdotes of experiences with anavar so you know what to expect. And make sure you also know what not to expect, often times anavar is faked and is actually Winston (winny) or even sometimes dbol. It would be good to read about those compounds to know what to expect in case this happens.
Milk thistle isn't necessary but also won't hurt. Again, based off consumerlab testing I would recommend "NOW Supplements, Silymarin Milk Thistle Extract, Extra Strength 450 mg". However Anavar is primarily metabolized through the kidneys, and with you only taking that at a low dose it really is unnecessary to take a liver support supplement.
The most important thing will be for you to stick to your diet and make sure you sre getting enough calories!! You can't build that booty bigger on a deficit
again I think a 200-300 calorie surplus along with intense lifting would be perfect to minimize fat gain.
