list all the supplements to lose fat and gain muscle. increase testosterone and decrese cholesterol

There isn’t one supplement stack shown here that reliably achieves all four goals. The transcript mentions these options, with evidence and cautions varying by supplement:

• Creatine: Discussed for training support and a slight increase in total testosterone; it can also increase DHT. The excerpts don’t give a dose. 1
• L-carnitine / acetyl-L-carnitine: Discussed as potentially supporting fat oxidation; one segment gives 500 mg–2 g daily in divided doses and reports small reductions in overall cholesterol and a slight increase in HDL. Another gives oral L-carnitine doses of 1–5 g daily, while warning about possible TMAO concerns, particularly with a dysregulated gut microbiome. 2 3 4
• Tongkat ali (longjack): Discussed for increasing total and free testosterone; the suggested range is 300–1,200 mg daily. It may be especially relevant during a calorie deficit, but the transcript notes that standardization matters and that taking it late can interfere with sleep. 5 6
• Vitamin D and boron: Correcting vitamin D deficiency may help optimize testosterone. Boron may acutely lower SHBG when it is high; the cited dose is 5–12 mg daily, and the effect may not last. 7
• Ashwagandha: Described as lowering cortisol and potentially raising testosterone indirectly. The discussion cautions against high doses for more than two weeks at a time. 8
• Shilajit: The evidence described for testosterone effects is limited and small; a small LDL reduction is also mentioned, so it is not presented as a strong choice for either goal. 9

For fat loss and muscle gain, these supplements aren’t substitutes for nutrition, training, sleep, and an approach you can sustain; the cited material does not establish a single supplement that accomplishes all the goals. 10
