The Skin & Hair Blueprint
16 weeks, five arms, one pick each
Everything on this page is free. The stack, why each pick beat its alternatives, every option, the bloodwork and the safety lines. The week-by-week schedule and the decision rules are the members half.
The single most useful thing to know in this category is the delivery ceiling: a molecule has to cross the stratum corneum before any of its biology matters, and size decides that. GHK-Cu is about 340 daltons and crosses. PDRN is 50–1,500 kilodaltons and largely does not. That one fact explains why most expensive serums do nothing, and it is the reason this page grades by whether it reaches the target rather than by what the label claims. The other thing worth saying: sunscreen and not smoking outrank everything below by a wide margin. Photoageing is the majority of what people call ageing.
Can you run all of them? Yes - and here is what it costs
This is a general protocol. You make the final call on how much of it to run — or have it built around your labs.
Which of these 5 is actually you?
This tells you where your biggest leverage is — where to start, not where to stop. Read the But line too: it is what each lane cannot do for you, which is the part a list of options never tells you.
Before any of it — the foundation
These four are not a disclaimer at the bottom of the page. They are the reason the rest of it works, and every one of them is free.
Growth hormone is released in pulses during deep sleep, insulin sensitivity is measurably worse after one bad night, and appetite regulation collapses without it. Every compound below works through a system that sleep already governs. This is not filler advice — it is the highest-leverage item on the page and it is free.
The single dietary variable with the most consistent evidence behind it for body composition, in both directions — building and preserving. Under-eating protein while running anything anabolic is paying for a signal with no substrate to act on.
Nothing here substitutes for mechanical tension. Compounds change how well you recover from and adapt to training; they do not replace the stimulus. A protocol run without training reliably produces the side effects and not the results.
Non-exercise activity is the largest and most variable component of daily energy expenditure, and it is the one that quietly falls when you start dieting. Tracking it stops the metabolic adaptation people blame on their thyroid.
The stack
Said once. Topical evidence is a different question from injected evidence for the same molecule, and this page grades the topical case. Retinoids and vitamin C have genuinely strong human data. Most peptides do not, and are labelled accordingly. Unproven is not the same as ineffective — each item's page carries its full topical evidence tier.
Each pick names what it was chosen over and why. That is the difference between a blueprint and a list — if you disagree with a choice, the alternative is right there and swapping it does not break the rest.
Peptides 3
Short amino-acid chains that signal rather than force. Almost all are injected or intranasal, they need reconstituting, and they are the reason most people are on this site.
A copper tripeptide at about 340 daltons — small enough to actually cross skin, which is what separates it from most of this category. Controlled work reports increased collagen and elastin, improved firmness and reduced fine lines over 12 weeks in facial creams. It is unusual in being evidenced AS a topical rather than borrowing from injection studies.
Tretinoin is the single best-evidenced topical anti-ageing ingredient that exists, by a distance — but it is prescription in most places and the retinisation period is real. Matrixyl and Palmitoyl Tetrapeptide-7 are signal peptides. Syn-Coll targets TGF-β. Pal-GHK is a fatty-acid-modified GHK for better penetration. GHK-Cu is the base because it combines real topical evidence with a molecular size that actually crosses. If you can get tretinoin, it beats everything here — and that is worth saying plainly rather than selling around.
Stack this arm deeper5 optional add-ons
Each of these sits in this same pathway, so it starts the week this pathway starts. Swapping one in for the pick above does not change the schedule.
The strongest topical anti-ageing evidence there is. Decades of vehicle-controlled trials showing increased epidermal thickness, collagen I production and measurably reduced wrinkles. Nothing else here is in the same evidential category.
The trade-off Prescription in most jurisdictions. The first six weeks — peeling, redness, irritation — are why most people quit before it works. Do not use it in pregnancy, and do not layer it with copper peptides in the same session.
A signal peptide that mimics a collagen fragment, telling the skin to behave as though damage occurred and repair is needed.
The trade-off Supplier-funded data dominates the evidence base. The mechanism is plausible and independent replication is thin.
Oral collagen peptides with randomised data on skin elasticity and hydration — specific di- and tripeptides appear to signal fibroblasts rather than merely supplying material.
The trade-off Needs 2.5–10 g daily for 8–12 weeks. The effect is real and modest, not transformative.
The required cofactor for prolyl hydroxylase — collagen physically cannot cross-link without it. Topical L-ascorbic acid at 10–20% also has real photoprotection data.
The trade-off Topical vitamin C oxidises fast — if it has gone orange it is doing nothing. Needs a low pH to penetrate, which irritates some skin.
Holds a thousand times its weight in water. Oral HA has surprising randomised data on skin hydration and wrinkle depth, probably via fragment signalling rather than intact absorption.
The trade-off Topically it needs humidity — in dry air it can pull water out of the skin, which is the opposite of the intent.

The 16-week schedule
What goes in, what comes out, and when. The exact doses for each phase are inside the Academy — the structure below is free because it is the part you need to decide whether this fits your life.

Each bar is a week block that compound is running. The shape is free — it is what tells you whether this fits your life. The doses for each phase are the members half.
Establish tolerance before adding anything else. An irritated barrier absorbs unpredictably and undoes the rest.
Introduce one active at a time. If something reacts you need to know which. And if your barrier is already compromised, spend these four weeks on a plain moisturiser and sunscreen — it is not a wasted month.
Nothing new. Minoxidil shedding peaks at 4-8 weeks and it is the drug working, not failing. Adding something here confuses the read.
The shed in the first weeks of minoxidil is expected — it pushes follicles into a new growth phase and the old hairs release first. Quitting at week three because of it is the single most common mistake in this arm.
First fair judgement point. Photograph in the same light.
Same light, same time of day, same angle — skin changes are slow enough that memory is useless and bathroom-mirror impressions are worthless. If you have no before photo, you have no result.
Everything here requires continued use.
Minoxidil stops working when you stop. That is the mechanism, not a failure — the effect requires continued signal, and any hair it maintained will shed within months of stopping. Decide up front whether that is a commitment you want.
Same lighting, same angle, monthly.
Gradual change is invisible day to day, which is why people abandon working protocols at month three and continue useless ones for years. The photograph is the only honest assessment available to you. Hair especially — shedding at week 4 to 8 on minoxidil is the drug working, not failing.

Unlock the schedule →Bloodwork
Hair loss especially has boring causes that people spend years not testing for. Ferritin is the big one. Low iron stores cause diffuse hair shedding well before anaemia appears, it is extremely common in women, and a normal CBC does not rule it out. If your ferritin is under about 40 and you are shedding, that is the finding. Thyroid — both directions cause hair loss and skin changes. Zinc for inflammatory skin and shedding. Vitamin D for both. One trap worth knowing: biotin corrupts thyroid immunoassays and produces wildly wrong results. It is in every hair-skin-nail supplement on the shelf. Stop it 48–72 hours before any blood draw or the panel you paid for is fiction.
Before you start
Everything, drawn before you start. This is the one that decides which pathway is actually yours - and the only one you cannot go back and collect later.
Around week 8
The short list, drawn while you are running it. Not a progress report - it is the draw that catches the things that go wrong quietly.
After
Drawn at the end, against your own baseline. This is what turns the protocol into information rather than a feeling.
All three are drawn at Quest, 2,000+ US locations, no doctor visit, HSA/FSA eligible. Prefer to pick and choose? Every marker above links to its own page, and the panel builder assembles any combination.
Adjusting it
A protocol you cannot adjust is a protocol you abandon. Four situations come up on nearly every run of this — nausea that will not settle, a three-week stall, hair shedding, glucose moving the wrong way. Each one has a specific answer, and the wrong answer to a stall is the reason most people end up on six compounds that each do nothing.
The four decision rules are inside
What to change, what to leave alone, and how to tell a real stall from a water shift. $10/mo.
Unlock the decision rules →The lines I'd stop at
- A mole that changes size, shape, colour or border — particularly on any melanocortin. That is a dermatologist appointment, not a wait-and-see, and it is the one genuinely serious risk on this page.
- Scalp irritation that is spreading, weeping or crusting. That is infection or contact dermatitis rather than an expected side effect.
- Dizziness, ankle swelling or a racing heart on minoxidil. That is systemic absorption showing up — more likely with large volumes or application to broken skin.
- A mole that changes shape, colour or size, or a lesion that bleeds and does not heal. Melanotan and any tanning agent makes this surveillance more important, not less.
- Rapid hair loss in patches, or hair loss with a rash or scarring. Scarring alopecia is permanent if untreated and the window is short.
- Chest pain, palpitations or sudden facial and ankle swelling on minoxidil. Systemic absorption is real, particularly from the higher-strength solutions.
It is built for the common case, not for you specifically. Compound selection and dosing genuinely do change person to person — training age, bloodwork, what you have run before, what you react to. Adjust it against your own numbers using the panels above, or if you want it built around your labs rather than the average, that is what 1-on-1 coaching is for.
