Bryan Johnson Is 10 Years Behind: SLIN Pills Solved HGH Insulin Resistance in 2016

Bryan Johnson Is Right About the Problem. He’s 10 Years Behind on the Solution.

Bryan Johnson posted again about managing his blood glucose on HGH. He’s running metformin SR, acarbose, ginger, cinnamon, turmeric, garlic, zinc, D3, DHEA, plus a low-glycemic-index diet with caloric restriction — all to keep his fasting glucose in range while he runs growth hormone for thymus rejuvenation. He’s tracking it on continuous glucose monitors. He’s measuring IGF-1. He’s doing the work.

And to his credit, he’s right about the problem. Every growth hormone protocol — injectable HGH, MK-677, GHRP-2, GHRP-6, ipamorelin, tesamorelin — produces downstream insulin resistance. Elevated GH blunts insulin receptor signaling. Glucose clearance slows. Fasting insulin creeps up. If you don’t manage the metabolic side, you eat the side effects: water retention, soft fat gain in a caloric deficit, eventually pre-diabetic bloodwork.

Bryan Johnson is genuinely aware of this. The issue is that he is 10 years behind Tony Huge on the actual solution.

Coach Trevor and I solved this in 2016. We didn’t solve it in a lab and write a paper nobody reads. We solved it on professional bodybuilders, watched the bloodwork over hundreds of cycles, and built a product around the mechanism. That product is SLIN Pills. And the reason Bryan Johnson — and most of the longevity space — is still wrestling with metformin and CGMs in 2026 instead of running a clean GH protocol with no side effects is not because the solution doesn’t exist. It’s because I get censored for being early.

The 2016 Discovery: Coach Trevor and the Bodybuilder Who Got Healthier on MK-677

Here’s how it actually happened.

Coach Trevor and I were running MK-677 on a professional competitor. The GH and IGF-1 numbers were exactly what we wanted. Sleep architecture deepened. Recovery accelerated. Muscle fullness went up. Then we pulled bloodwork — and his fasting glucose was creeping. Insulin sensitivity moving the wrong direction. The classic GH side effect everybody complains about.

We didn’t quit the cycle. We added SLIN Pills.

What happened next was not what we predicted at the time. We expected SLIN to neutralize the problem — to hold glucose at baseline. Instead, the bodybuilder came out of the cycle with better insulin sensitivity than he started with. Less water retention. More dry tissue. Bloodwork that looked better than it did before he ever touched MK-677.

We ran it again. Different test subjects. Same result. Every single experiment combining a GH-class compound with SLIN Pills produced subjects who finished the cycle with improved insulin sensitivity compared to baseline. Not maintained — improved. Better than natural.

That stopped being a “side effect mitigation” story. It became a health optimization story.

The Mechanism: Why SLIN + GH Is Synergistic, Not Competitive

This is Tony Huge’s Law 5 — Independent Receptor Stacking in its purest form. Different receptors operate on independent signaling pathways. You can activate the GH/IGF-1 axis and the insulin sensitization axis simultaneously without diminishing returns, because they converge on the same outcome (anabolic, recomp-favorable metabolism) through entirely separate mechanisms.

What HGH and MK-677 Do

• Injectable HGH binds the GH receptor directly, driving JAK2-STAT5 signaling and downstream IGF-1 production from the liver.
• MK-677 binds the ghrelin receptor (GHSR-1a) on the pituitary, triggering pulsatile endogenous GH release.
• Either pathway elevates GH, which blunts insulin signaling at the cellular level. This is the side effect Bryan Johnson is wrestling with.

What SLIN Pills Do

SLIN Pills run on completely separate machinery:

• Berberine — activates AMPK, the cellular energy sensor. AMPK activation increases glucose uptake into muscle independent of insulin. It’s the same downstream effect as exercise.
• Chromium — potentiates insulin receptor signaling, increasing the cell’s responsiveness to whatever insulin is circulating.
• Alpha-lipoic acid — recycles cellular antioxidants and upregulates GLUT4 transporter expression, the channel that pulls glucose out of the bloodstream into muscle tissue.
• Cinnamon extract (cinnamaldehyde) — slows gastric emptying and enhances insulin receptor phosphorylation.
• Bitter melon — contains charantin and polypeptide-p, which mimic insulin action at the receptor.

None of these compete with the GH axis. None of them blunt GH or IGF-1 signaling. They’re operating on the insulin/glucose disposal side of the equation while GH is doing its work on the anabolic side. Independent pathways. Additive outcomes.

That’s why the combination doesn’t just neutralize the side effect. It overshoots in the favorable direction. The GH cycle pushes anabolic signaling. The SLIN cycle pushes glucose into muscle instead of fat. The two together produce a body composition outcome that neither does alone — and bloodwork that’s better than baseline.

What Bryan Johnson Is Actually Doing

Bryan Johnson’s protocol for managing HGH-induced glucose dysregulation is, in his own published notes:

• Metformin SR (insulin sensitizer, AMPK activator — same mechanism as berberine, weaker on glucose disposal, stronger on hepatic gluconeogenesis suppression)
• Acarbose (alpha-glucosidase inhibitor — slows carbohydrate absorption, doesn’t sensitize)
• Ginger, cinnamon, turmeric, garlic, zinc, D3, DHEA
• Low-GI / caloric restriction diet

This is a defensive protocol. It’s playing the glucose problem to a draw. He’s keeping his blood glucose in range, which is a real win compared to ignoring the problem — but he’s not capturing the upside.

SLIN Pills do everything that stack does, in one pill, with the addition of GLUT4 upregulation and direct insulin receptor potentiation that the metformin-acarbose combo doesn’t deliver. And we’ve been running it for ten years. The bloodwork data is already in. The Mr. Olympia-level competitors who follow this protocol have longer, healthier careers than the ones running injectable HGH and pin-point insulin alone — because their cycles end with improved metabolic health, not damaged metabolic health.

What Bryan Johnson Will Eventually Figure Out

Bryan Johnson will get to this protocol. The longevity space is converging on it from multiple directions — the GLP-1 / GIP dual agonist work (tirzepatide, retatrutide) is arriving at insulin sensitization through pharmaceutical channels. He’ll either find SLIN Pills directly or he’ll arrive at the same mechanism through a different stack. It will take him years. And during those years, hundreds of thousands of people will be following his protocol and accepting unnecessary insulin resistance as the cost of GH therapy — when the actual solution has been available since 2016.

This is the pattern. I figure something out. We document it on bodybuilders. We publish the bloodwork. The mainstream longevity space catches up 10 years later, with worse data and a more expensive supplement stack.

Why You Don’t Already Know This: The Censorship Problem

The reason Bryan Johnson is the household name in longevity and Tony Huge is not — despite Tony Huge solving the central GH problem a decade earlier — is straightforward.

I get censored for being early.

I was talking about MK-677 and growth hormone optimization for athletes when YouTube was still demonetizing every video on the topic. I was running blood-tested protocols on professional bodybuilders before “biohacking” was a word people used in podcast titles. I was open about peptides, SARMs, and metabolic optimization stacks before any of that was platform-acceptable content. The result: my reach gets throttled. Videos get removed. Channels get demonetized. The information doesn’t propagate the way Bryan Johnson’s clean, Netflix-friendly version does.

That’s the trade. Early movers don’t get the audience. Late movers get the audience because by the time they show up, the platforms have decided the topic is mainstream enough to allow.

If you want to know what biohacking looks like 10 years in the future, you can’t watch the people the algorithm is currently promoting. Those people are showing you the mainstream of today, which is the underground of 10 years ago. You have to find the people who already lived through it.

That’s why the Tony Huge Skool community exists. It’s where the protocols that get censored on the open internet actually live. Where the bloodwork data sits. Where the underground research network shares what’s working before it becomes a Netflix documentary.

Bryan Johnson is showing you 2016. The Skool community is showing you 2036.

The Protocol

Dosing

• SLIN Pills: Take with the largest carbohydrate meal of the day, or with the last meal before bed. That’s when glucose disposal matters most. Run continuously throughout any GH cycle — there’s no downregulation concern.
• HGH: Standard protocol dosing per your bloodwork.
• MK-677: 12.5–25 mg before bed. Cycle 5 months on, 1 month off, to prevent ghrelin receptor desensitization.

Bloodwork

Pull baseline before starting. Re-pull at 8 weeks. Track:

• Fasting glucose (target: under 90 mg/dL)
• Fasting insulin (target: under 8 µIU/mL)
• HbA1c (target: under 5.2%)
• IGF-1 (your individual upper limit per your protocol)

If fasting glucose is creeping above 100, increase SLIN dose or tighten carbohydrate timing. If it stays in the 80s, you’re managing the metabolic side perfectly while capturing the full upside of the GH protocol.

Bottom Line

Bryan Johnson identified the right problem. He’s solving it 10 years late and with an inferior stack. The actual solution has existed since 2016 and is built into a single product designed specifically for this exact mechanism.

If you’re running any GH-class compound — injectable HGH, MK-677, GHRPs, tesamorelin, peptide bioregulators that touch the GH axis — and you’re not running SLIN Pills underneath it, you’re leaving the entire upside of the protocol on the table. You’re accepting unnecessary insulin resistance. You’re getting Bryan Johnson’s 2026 protocol instead of Tony Huge’s 2016 protocol.

The bloodwork is already in. The mechanism is published. The product is on the shelf.

The only thing left is whether you want biohacking from 10 years ago, or biohacking from 10 years in the future.
