What is AfterDark XYO Test.

XYO Test is a multi layer testosterone booster in 100 capsules built for advanced users. It groups its ingredients into complexes targeting free testosterone, SHBG, LH and FSH, and GnRH, alongside a vitamin complex and an absorption enhancer.

What is in the free testosterone complex.

Tongkat Ali extract 200:1 at 500 mg, Fadogia Agrestis at 500 mg, Shilajit extract at 500 mg and Dioscorea Nipponica at 100 mg.

What is the SHBG complex for.

SHBG binds testosterone and makes it unavailable. The complex uses stinging nettle root at 100 mg, DIM at 100 mg and boron citrate at 100 mg yielding 5 mg boron, all working to reduce SHBG binding and raise bioavailable testosterone.

Why is boron included.

Boron citrate yielding 5 mg of boron is one of the most researched minerals for increasing free testosterone and reducing SHBG, and the dose here is set for that hormonal impact.

What is the LH and FSH complex.

It contains Vitex Agnus-Castus at 50 mg, traditionally used to support pituitary health and LH and FSH regulation, along with acetyl-L-carnitine at 50 mg, DHEA at 50 mg and gamma-butyrobetaine at 50 mg.

What vitamins does XYO Test contain.

Vitamin D3 at 30 mcg, which is 1500 IU, plus vitamin C and a full B complex covering B1, B2, B3, B5, B6, B9 and B12 for energy metabolism, neurological balance and hormonal support.

Can XYO Test be used after a cycle.

Yes. It is designed with that in mind. Shilajit works well in post cycle hormone normalisation, DIM is particularly useful during or after enhanced cycles, and Vitex supports natural hormone rhythms during recovery phases.

What does the pomegranate extract do.

Pomegranate extract standardised to 40% ellagic acid at 50 mg is included as part of the GnRH complex for antioxidant activity and its potential effects on hormone release and nitric oxide levels.

How do I take XYO Test.

Take four capsules daily with food. Use it consistently for six to eight weeks, either standalone or stacked post cycle.

Can I combine XYO Test with other testosterone boosters.

It is not advised. Avoid combining it with other test boosters or hormonal agents unless you are being guided, since the formula is already multi layered and strongly dosed.
