How it worksVersion 2.0 is made once. When this batch sells out it is gone; the next version is announced before it is made. If this formula is working for you, tell us to keep it — and buy a few extra bottles just in case.
Read the changelogL-DOPA precursors work best with breaks. Jason rotates this through the month rather than taking it daily.
Every NEX-GEN formula starts at Version 2.0 and later versions may be announced each quarter. Each run is a single batch — once it sells out, that exact version is retired. If you love a version, tell us to keep it, and buy a few extra bottles just in case.
Pre-order adds the item to your saved cart and emails a confirmation that your bottles are reserved. No payment is taken now; you will be prompted to complete checkout when the Version 2.0 batch releases in early 2027.
Version 2.0 ships early 2027 in the order pre-orders were placed. Pre-orders open January 1, 2027; until then you can save it to your list at no cost.
