The Ironman Stack

Peptides are an optimization layer. Sleep, protein, training, and recovery are the base.

The Architecture

Five systems. Each peptide earns its place because it targets a layer the others don't.

The Peptides

GLOW — Structural Repair

Form: 70mg combo vial (50 GHK-Cu / 10 BPC-157 / 10 TB-500) · Route: sub-q · Cadence: per cycle

Three peptides in one vial. Overlapping mechanisms, different tissue targets.

GHK-Cu — a copper tripeptide that declines sharply after 30. Upregulates collagen, elastin cross-linking, and antioxidant defense across hundreds of gene pathways. Strongest evidence is dermal: firmer skin, faster wound closure, follicle stimulation. Copper itself is the cofactor for lysyl oxidase, which matters for every connective tissue in the body.

BPC-157 — a 15-amino-acid fragment from human gastric juice. Drives angiogenesis, upregulates GH receptors in tendons, modulates nitric oxide. Animal data is strong; human RCTs are limited but anecdotal evidence in sports recovery is extensive. Your protocol also includes 500mcg oral AM — lower bioavailability but good for gut-specific effects.

TB-500 — a synthetic Thymosin Beta-4 fragment. Regulates actin, promotes cell migration, reduces scar tissue. Stacking with BPC-157 is popular but likely redundant — the angiogenic pathways overlap.

CJC-1295 + Ipamorelin — Growth Hormone

Form: 5mg/5mg combo vial · Route: sub-q · Dose: 50mcg + 50mcg · Cadence: pre-bed, empty stomach · Cycle: 8–12 weeks on, break

Not exogenous HGH. Works with your pituitary instead of replacing it.

CJC-1295 binds GHRH receptors. Ipamorelin amplifies the resulting pulse without spiking cortisol, prolactin, or hunger — unlike older GHRPs. Together: a larger, cleaner release than either alone.

Deepest sleep in a week. Recomp is gradual, 3–6+ months. Think optimizer, not builder. Cycle to preserve pituitary responsiveness.

Retatrutide — Metabolic Reset

Form: 24mg vial, reconstitute with 2.4mL BAC water → 10mg/mL · Route: sub-q · Cadence: weekly · Titration: escalate every 4 weeks if tolerated

The most powerful metabolic peptide currently available. What makes it different is in one receptor.

The glucagon receptor is what separates retatrutide from tirzepatide. It turns on the metabolic furnace — driving liver fat oxidation and energy expenditure simultaneously.

Trial results: up to 24–29% body weight reduction at peak dose, ~86% liver fat reduction in MASLD patients. Watch for modest HR increase (~6.7 bpm, normalizes) and cutaneous hyperesthesia in ~21%.

Dosing chart at 10mg/mL:

Start low. Escalate slowly. The titration philosophy is the whole game.

MOTS-c — Mitochondrial Layer

Form: 20mg vial · Route: sub-q · Cadence: per cycle

A 16-amino-acid peptide encoded in mitochondrial DNA — one of the first discoveries that mtDNA signals outward to the nucleus and to distant organs.

Primary mechanism: AMPK activation. The same pathway triggered by exercise, fasting, and metformin. Shifts cells toward fat oxidation, enhances muscle glucose uptake, drives mitochondrial biogenesis.

Doubled running capacity in aged mice. Human data is early but mechanistically aligned with every other intervention that works. Runs quietly in the background while the others do the visible work.

Cognitive Tier — Semax, Selank, Cerebrolysin

Status: not in active protocol · Summarized for completeness and future consideration

Three peptides targeting a different axis: the brain. Most data is Russian, which is not a disqualifier but requires calibration.

Semax — a fragment of ACTH. Modulates BDNF, dopamine, and serotonin. Used for acute cognitive enhancement, focus, and stroke recovery in Russian clinical settings. Intranasal route is standard. Reasonable evidence for short-term cognition; speculative for chronic neuroprotection.

Selank — a tuftsin analog. Modulates GABA, serotonin, and the immune system. Anxiolytic without sedation — reduced anxiety, stabilized mood, mild cognitive lift. Intranasal. The most defensible "take the edge off without being blunted" option in the class.

Cerebrolysin — a mixture of neuropeptides and amino acids derived from porcine brain. Mimics endogenous neurotrophic factors. This is the serious one: strongest evidence in the cluster for stroke recovery, TBI, and dementia adjunct. IM injection, multi-week courses. Not a casual addition.

Semax and Selank are low-stakes experiments. Cerebrolysin is a clinical-grade intervention that deserves physician supervision.

Epithalon — Longevity

Form: vial · Route: sub-q · Cadence: cycled

A synthetic tetrapeptide (Ala-Glu-Asp-Gly) targeting the pineal gland. Claims: telomerase upregulation, melatonin normalization, circadian rhythm support.

The most defensible claim is sleep quality. Telomerase and lifespan extension are speculative in humans. Most supporting data comes from Russian research groups with limited Western replication. Enthusiasm outruns the evidence. Treat accordingly.

Sourcing

Three things matter. Everything else is marketing.

1. Third-party COA — verifiable on the testing lab's own site, matched to your batch number. Unverifiable COAs should be treated as no COA at all.
2. Endotoxin screening — critical for reconstituted solutions. Most budget vendors skip it.
3. Heavy metals testing — the extra layer very few vendors provide.

Primary: Peptide Partners. COAs from TrustPointe, Chromate, and BioRegen — each independently verifiable. Endotoxin and heavy metals screening performed. Batch traceability published.

Red flags: suspiciously low prices with no COA · no batch numbers · sterile water marketed as reconstitution solution · COAs that don't name the testing lab or can't be verified independently.

Execution

The Kit

Reconstitution

Swab both vial tops. Draw BAC water with the mixing syringe. Inject slowly down the glass wall — never onto the powder. Swirl gently. Never shake — shaking denatures peptides. Let it fully dissolve before drawing a dose. Label. Refrigerate. Use within 28 days.

Injection

Subcutaneous site: abdomen (2" from navel), outer thigh, or back of arm. Pinch skin, insert at 45° or 90° depending on body fat. Inject slowly. New needle every time. Rotate sites to prevent lipohypertrophy.
