Ostarine is my bread and butter. Most tested, the highest number of clinical trials for safety, lowest suppression and sides frequency. S4 seems very mild on the sides other than Vision issues which can occur at or above 25 mg dosage which would warrant immediate discontinuation. S4 is more beneficial for cutting tho. LGD is slightly more tested than Rad 140 , more geared for size and mass while RAD hits strength more but sides are higher with both as suppression is increased. Again, not an issue if you have exogenous test through HRT. LGD has higher reported shedding while being used however because SARMS do NOT aromatize into estrogen or DHT, theoretically speaking it should have zero effect on increasing the rate of male pattern baldness, it would just be telogen effluvium. S23 is hardly tested and rough on the system, wouldn't suggest it. Honestly if you really want to try a SARM I say start with an ostarine cycle, assuming you're on HRT, measure its effects on your liver enzymes and cholesterol post cycle. If you wanna move up from there, try LGD at 3-5 mg or Rad at 10-15 mg, don't go higher. Don't run them concurrently either, that's a waste. Get your bloods done after each cycle, and learn how your system responds to each individual compound, we all react differently. Finally, make sure you have a genuine, reputable vendor, do your research, this is critical. Keep an AI or Serm on hand during cycle whether or not you're on HRT in case of high estrogen sides. If you're not on HRT, this should only be an issue until your HPTA responds to the exogenous administration and suppresses appropriately. If you are on HRT, you have to observe yourself throughout the cycle because when the SARM attaches to the AR site, basically your test is gonna float and potentially aromatize. Obviously it's a bit more complex than that but that should get you started.
