The SARMS triple stack works freaken great, and my wife has used it several times with amazing results. What we like about it is the absolute absence of side effects, and zero risks of virilization. So this is a win-win option for a lady looking to get into great shape for a show. Just make sure to be getting the legit SARMS from a reliable source, since there are many fakes sold that are either bunk, or laced with prohormones. Personally, I would go with sarms1.com - this is my go-to source for SARMS.
As for clenbuterol, it was never meant for fat loss purposes, and when taken at dosages needed for that it will cause a lot of side effects (such as headached, crams, increased blood pressure, stomach disorders, insomnia, and many more stim related side effects). Besides, it is completely catabolic, so it will not only burn fat, but also lean muslce mass. Therefore, it will mostly reduce your overall mass, not just fat. What's more, it will also increase cortisol levels, which may lead to further fat gains, and other undesired effects.
For this reason, I strongly recommend you to use some safer alternatives that were meant for fat loss and recomping all along. For instance, Cardarine GW will effectively burn fat, but at the same time it will maintain your lean mass. Additionally, it will greatly enhance your endurance and recovery, leading to improved cardio performance, which will ultimately help with fat loss even more. The best part of it is that it causes no side effects at all.
You can stack it with N2Slin, which is a potent nutrient partitioner, which will redistribute insulin into the muscles instead of fat. It does not have side effects either, so it is completely safe to use. I have personally used both, and my wife has also done so - the results were always beyong expectations, and there were no issues at all.
