Mindsip insights from this episode:

Avoid digestive enzymes with oral peptides for effective absorption

Taking digestive enzymes alongside oral peptides is contraindicated because the enzymes will break down the peptides, preventing their absorption.

Utilize NACET for enhanced bioavailability and brain access

NACET is a form of N-acetylcysteine with an ethyl ester group, making it far more bioavailable (60% vs 2-4%) and able to cross the blood-brain barrier.

Utilize icarin as a natural alternative to Viagra

Icarin, the active compound in horny goat weed, is a natural PDE5 inhibitor that has effects similar to Viagra.

Utilize oral TB-500 for anti-inflammatory and healing benefits

By isolating the short-chain terminal ends of the Thymosin Beta 4 (TB4) peptide, you can get its anti-inflammatory and healing benefits orally without injection.

Ensure peptides are under 10 amino acids for oral bioavailability

As a general rule, peptides with an amino acid chain shorter than 10 are small enough to be orally bioavailable and absorbed systemically.

Boost athletic performance with 5-Amino-1MQ to enhance NAD levels

The peptide 5-Amino-1MQ improves athletic performance by inhibiting the NNMT enzyme, which boosts NAD levels by recycling it through the salvage pathway.

Optimize GAA absorption with methylation support to enhance creatine benefits

GAA (guanidinoacetic acid) is a creatine precursor that absorbs significantly better than creatine but requires methylation support (like TMG) to avoid raising homocysteine.

Pair TUDCA with chitosan to prevent toxin recirculation

TUDCA thins bile and can cause a massive toxin dump from the liver, so it's best paired with a binder like chitosan to prevent toxin recirculation.
