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.

#enzyme

#peptides

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.

#bioavailability

#supplement

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.

#supplement

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.

#healing

#peptides

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.

#bioavailability

#peptides

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.

#NAD

#peptides

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.

#creatine

#TMG

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.
