Nobody can stand in your shoes and determine whether the tradeoffs between efficacy and tolerability make sense for you to take it.
Here is what you need to actually know to do this balancing of interests for yourself:
Aspirin doses of 80 - 100 mg daily ("daily low dose Aspirin") broadly reduce cardiovascular disease risk rather than lowering HCT. It prevents clotting by inhibiting cyclooxygenase (COX) enzyme in thrombocyte (platelets), thereby ↓thrombotic but ↑bleeding risk. Daily, low dose Aspirin is not recommended by European Guidelines, that are known for risk averseness versus North American medical recommendations. There is a risk of rebound upon cessation/withdrawal if you are to stop the daily low dose Aprisin, in the form of an increased risk of a thrombotic event for weeks after Aspirin discontinuation.
The absolute risks of thromboembolic events are low for otherwise healthy men with mild erythrocytosis/polycythymia characteristic of TRT or AAS use. For normal men, the
while the relative risk seems tremendous in that for every 5% ↑ in haematocrit, there was a 33% ↑ in the probability for a venous thromboembolic event in men, adjusted for age, BMI, and smoking, the picture is quite different in terms of absolute risk.
In terms of absolute risk of a thromboembolic event in normal/healthy men with average haematocrit (43 - 46%), there is a 0.16% probability for such an event within 10 years (1.6 per 1,000 person-years). If haematocrit ↑ by 5%, that chance ↑ by 33% to 0.21% within the next 10 years (2.1 per 1,000 person-years).
All of this information comes from
@PeterBond's
Book on Steroids. It should be required reading for every AAS user in my view. I believe that it qualifies as light reading for an average university-educated person, and can be used a reference for all sorts of questions that arise on a daily basis on this forum.
While Aspirin on an empty stomach can hurt the stomach lining, besides that, daily low dose Aspirin is regarded as quite safe for the kidneys and liver. It actually enhances/increases bloodflow to the extremities, one important mechanism in its reduction of CVD risk.
