Stanozolol can be used without severe cardiovascular strain but should not be used if you already have cholesterol issues. It is imperative that cholesterol issues are monitored during use and that a cholesterol friendly lifestyle is followed. A healthy diet that is rich in omega fatty acids and low in simple sugars and saturated fats is very important. Equally important is regular cardiovascular activity. If these are things you cannot do you should not use this steroid. It is also recommended that a cholesterol antioxidant supplementbe used.
Sterols are essential for all eukaryotes . In contrast to animal and fungal cells, which contain only one major sterol, plant cells synthesize an array of sterol mixtures in which sitosterol and stigmasterol predominate.  Sitosterol regulates membrane fluidity and permeability in a similar manner to cholesterol in mammalian cell membranes.  Plant sterols can also modulate the activity of membrane-bound enzymes.  Phytosterols are also linked to plant adaptation to temperature and plant immunity against pathogens.
