I would be worried about lgd's impact on cholesterol in studies a mere 1 mg a day caused reduction. Anecdotally i heard people report terrible bloodwork on sarms,
I would go with nandrolone (with test ofc) if you are mainly worried about shedding or primo if you want something milder to stack with test.
I agree with staying away from c17 aa's (although i am on fence on trying anavar next cycle). They annihilate cholesterol and they also stress liver, some more and some less.
500 test and my cholesterol is mid range, total and ldl, hdl is towards low end, but definitely not out of range. But at least test doesnt destroy your lipids. Just keep your diet "clean" and try to stay away from animal saturated fat (seemingly worked for me).
