Also known as
NAC
Searches for NAC at PoseidonRX resolve to two Magnus Gain Mass Course stacks. Neither is an N-acetyl cysteine supplement; both are cycle packages that include Anastrozole. The underlying compound is an anti-estrogen, and the listing exists so buyers can find it under this alternate name. PoseidonRX ships only within the European Union, and these two items differ by their numbered course format rather than by any other component.
What NAC refers to here
NAC is used as an alternate name for Anastrozole, the anti-estrogen included in both Magnus Gain Mass Course packs. It is not a separate active ingredient, nor does it have its own product page at this shop. The two numbered courses are distinct products, but they share the same Anastrozole component. Buyers should be aware that Anastrozole is a 17-alpha-alkylated compound and carries hepatotoxicity risk; baseline and periodic blood-work is advised.
Choosing between the two products
PoseidonRX sells Anastrozole only inside these two Magnus Gain Mass Course packs. There are no other forms of it in this catalogue, and the EU-only shipping applies to both. The difference between the numbered courses is their specific stack composition; neither includes any other anti-estrogen. Athletes comparing them should look at the full component list and the total daily dosing rather than assuming one is a simple variant of the other.
