Alright gents, listen up. Most of you think nicotine is an absolute death sentence for your gains and height, but that is just a massive normie cope. If you actually look at the data instead of blindly repeating what mainstream doctors say, there is a literal golden sweet spot for nicotine and cotinine that maximizes total testosterone and keeps your growth plates open for longer. I am breaking down the whole biochemistry behind this so you can understand the exact mechanisms.

Let us look at the actual NHANES study data, which shows a clear non-linear, inverted U-shaped correlation between serum cotinine (the main metabolite of nicotine) and total testosterone.

The data proves that up to ~400 ng/mL of serum cotinine, total T literally goes up. The absolute peak and inflection point happens around 487-508 ng/mL. If you cross this threshold and overdo it, your endocrine system nukes itself and T drops hard. So the entire protocol revolves around staying perfectly at that 400 ng/mL sweet spot.

Here is exactly how this works on a deeper biological level:

Mechanism 1: The Testosterone Stimulus

When nicotine enters your blood through your lungs or oral mucosa, it passes through the liver where the CYP2A6 enzyme metabolizes roughly 70-80% of it into cotinine.

Nicotine -> nAChR activation -> increased catecholaminergic transmission -> altered hypothalamic-pituitary-gonadal (HPTA) regulation -> Leydig cell stimulation -> upregulation of testosterone synthesis -> High T.

Basically, nicotine binds to nicotinic acetylcholine receptors (nAChR) in the central nervous system. This spikes your catecholaminergic transmission, triggering a stress response that forces the HPTA axis to signal your Leydig cells to churn out more testosterone.

On top of that, nicotine and cotinine act as competitive inhibitors of the aromatase enzyme (CYP19A1). Aromatase is the exact enzyme responsible for converting your testosterone into estradiol (E2). By blocking its activity, less testosterone breaks down into estrogen, meaning your total circulating T stays elevated.

Mechanism 2: The Growth Plate Delay Hack

Now, how does this affect your height? What actually closes your growth plates? Most people think it is testosterone, but that is wrong. It is estrogen (estradiol/E2) binding to ERα/ERβ receptors in your chondrocytes (cartilage cells inside the plates) that causes the final epiphyseal fusion.

Nicotine -> decreased aromatase (CYP19A1) activity -> decreased conversion of testosterone to estradiol -> decreased E2 -> decreased ERα/ERβ activation in chondrocytes -> delayed estrogen-dependent maturation of the epiphyseal plate -> later growth plate closure.

By maintaining that optimal 400 ng/mL cotinine level to block aromatase, you systematically lower your E2 levels. Lower E2 means the estrogen-dependent maturation of the epiphyseal plate is heavily delayed. Your growth plates stay open for longer, buying you crucial time to maximize your height potential.

How to Optimize and Fix the Side Effects:

You cannot just blindly chain-smoke and expect to grow taller. If you do this raw, you will fail due to a couple of biological counter-mechanisms:

1. The SHBG Trap: Nicotine raises Sex Hormone-Binding Globulin (SHBG), which binds to free T and makes it useless. To fix this, you must stack Boron (10mg/day) or Proviron. This crushes SHBG, ensuring that the extra testosterone you are generating stays free, active, and functional.
2. The Vasoconstriction Problem: Nicotine restricts blood flow, meaning your cartilage plates can starve without nutrients. Drop the cigarettes and trash flavored vapes entirely—the heavy metals and combustion toxins destroy Leydig cells anyway. Use pure white nicotine patches to get a completely flat, controlled background release of 400 ng/mL cotinine without erratic spikes, and add L-Citrulline or Agmatine to force powerful vasodilation so nutrients actually reach your bones.

This is pure, high-IQ biochemistry. What do you guys think, am I cooking or is this legit?

In a practical sense though you're better off with a genuine AI but ig your reasoning is correct.

True, but pharma AIs won't give you the nAChR stimulus. This hits both targets at once
