In conjunction with B12, these amino acids work to pump up your natural metabolic rate, meaning your body becomes more proficient in turning food into energy that you can use all without storing more than you need, meaning its more difficult to gain weight
Legitimate Research Directions: Some peptides DO have potential and are being properly studied: Thymosin Alpha-1: Immune support (approved in 35+ countries, trials in US) BPC-157: IF proper human trials ever happen LL-37: Antimicrobial applications Others: Many peptides have theoretical promise But ONLY if studied properly: Randomized controlled trials Safety studies FDA approval process Medical supervision The Problem: Most "wellness peptides" will NEVER go through this process because: They can't be patented (no profit incentive) Companies would rather sell in gray market Proper trials cost $100M+ If trials show they DON'T work, the market disappears So we're stuck in limbo: promising animal data, zero human data, aggressive marketing
