One regulatory note worth holding alongside his framing: the FDA placed several of the peptides he discusses (including BPC-157, CJC-1295, and Ipamorelin) onto a Category 2 list in 2023, citing a lack of safety data rather than reported harms
RKT Bundle with Peptides Synthesized copper peptides work just as well as the naturally occurring ones, meaning hair care products are a great way to promote a healthy set of hair

NAD powers cellular energy while NAC protects against damage - NAD drives ATP production and DNA repair, while NAC boosts glutathione for antioxidant defense Both compounds decline significantly with age - NAD+ levels drop to less than half by age 60, making supplementation increasingly important for vitality Timing matters for optimal absorption - Take NAD precursors (NMN/NR) with food, but NAC works best on an empty stomach They work synergistically when combined - NAD and NAC can be safely stacked together to address both energy metabolism and cellular protection Different forms offer varying benefits - NMN and NR serve as effective NAD precursors, while standard NAC dosing ranges from 600-1,800mg daily Rather than choosing between NAD vs NAC, the most effective approach combines both supplements to create a comprehensive cellular health strategy that addresses energy production, DNA repair, and antioxidant protection simultaneously
