Start The Full Compound

Forty bottles. Twelve experts who disagree. A new ingredient every month with a name you cannot pronounce and a before-and-after you do not believe.

Somewhere in there was the quiet question you actually had: why do I feel flat at three in the afternoon, wired at eleven at night, and sore for two days after a workout that used to be easy?

You do not need more. You need less, done properly, for long enough to notice.

Five basics. One routine. Every amount on the label.

Why Compound Y

Most supplement cupboards look the same. Fourteen bottles, three half full, none of them doing anything you can feel. More was never the answer.

So we started from the other end: only ingredients with real evidence behind them, at honest doses, built into routines simple enough to keep.

Small things taken daily barely register in the first week and add up over months. That is the whole idea, and it is the name. Compound Y is the question to ask before you add anything: why this, why this dose, why every day.

Five basics, for women and men. Each one is a single ingredient at a clearly printed dose, tied to a moment in your day.

Any time, daily

Creatine

Creatine

5 g creatine monohydrate, 1,000 mg sodium, 200 mg potassium and 60 mg magnesium per scoop. Lemon, stevia. 30 scoops.

The most studied supplement there is, in a drink you will actually finish. Supports strength, power and performance in high-intensity training, and replaces the electrolytes you lose in sweat.*

$34.89 one-off, or monthly in a routine from $2.97 a day

Before you take it

Contains 1,000 mg sodium per serving. Talk to your doctor first if you have high blood pressure, heart or kidney disease, or follow a sodium-restricted diet. Not recommended during pregnancy or breastfeeding. Talk to your doctor before use if you are pregnant, nursing, taking medication, or have a medical condition. Not for anyone under 18.

Evening

Magnesium Glycinate

275 mg elemental magnesium per 3 capsules, from magnesium glycinate. 90 capsules, 30 days.

The mineral most people are short on, in the form that is gentle on the stomach. Supports relaxation, normal muscle and nerve function, and a normal sleep cycle. Taken before bed.*

$28.99 one-off, or monthly in a routine from $2.97 a day

Before you take it

Talk to your doctor first if you have kidney disease. Take at least two hours apart from antibiotics or osteoporosis medication. May cause loose stools; reduce the dose if so. Talk to your doctor before use if you are pregnant, nursing, taking medication, or have a medical condition. Not for anyone under 18.

With breakfast

Probiotic 40 Billion

40 billion CFU from four named strains (La-14, Bl-04, Lp-115, Lpc-37) in an 800 mg blend, with prebiotic fibre, in a delayed-release capsule. 60 capsules, 30 days.

Four strains you can look up, in a capsule built to get past stomach acid. Supports digestive balance and a healthy gut microbiome. Taken with breakfast.*

$34.99 one-off, or monthly in a routine from $2.97 a day

Before you take it

Talk to your doctor first if you are immunocompromised, undergoing cancer treatment, or have a serious medical condition. Talk to your doctor before use if you are pregnant, nursing, taking medication, or have a medical condition. Not for anyone under 18.

Morning, in a drink

Collagen Peptides

Grass-fed bovine collagen peptides, 280 g tub. Half a scoop (10 g) a day, the dose the trials used, so a tub lasts 28 days. Unflavoured, dissolves in anything.

The main structural protein in skin and joints, broken down so it absorbs. Supports skin hydration and elasticity and joint comfort in active adults. Goes in coffee.*

$39.09 one-off, or monthly in a routine from $2.97 a day

Before you take it

Contains bovine collagen. Not a complete protein source. Talk to your doctor before use if you are pregnant, nursing, taking medication, or have a medical condition. Not for anyone under 18.

With breakfast

D3 + K2

5,000 IU (125 mcg) vitamin D3, 100 mcg vitamin K2 (MK-7) and 210 mg calcium per capsule. One capsule a day with a meal. 60 capsules, two months.

The vitamin you would make from sunlight and mostly do not. Supports bone and normal immune function; K2 helps direct calcium to bone. One with breakfast.*

$26.99 one-off, or monthly in a routine from $4.63 a day

Before you take it

5,000 IU of vitamin D per capsule is above the 4,000 IU daily upper limit for adults, so take one capsule a day at most and never with other vitamin D or calcium supplements. Contains vitamin K: do not use if you take warfarin or another blood thinner without talking to your doctor. Talk to your doctor first if you have kidney disease or high blood calcium. Talk to your doctor before use if you are pregnant, nursing, taking medication, or have a medical condition. Not for anyone under 18.

Week 1

You will not feel much.

That is normal, and most brands will not tell you. Magnesium and D3 build up over weeks, creatine saturates in about a month. What you have on day seven is a routine, and that is the part that was missing.

Month 1

The evenings end easier.

Same things, same times. The bottle arrives before the last one runs out, so the habit never restarts from zero. You stop thinking about it, which is the point.

Month 6

This is what adding up looks like.

Nothing dramatic happened on any single day. You just feel steadier than you did, and you cannot point to the morning it changed. That is compounding.

What is in the bottle

Every ingredient and every amount is printed, on the label and on this page. If a product needs a paragraph to explain why it is good, it is not on this site.

Made
In facilities that follow FDA current Good Manufacturing Practices (cGMP), and shipped from within the US.
Not in here
No weight-loss blends, no hormones, no gummies with sugar doing the work. No product we could not explain in one sentence. The one blend is the probiotic: its four strains are named, and the label gives their combined amount.
Diet
Capsules are vegetable-based (hypromellose). Collagen is from cattle (bovine). Lemon creatine is sweetened with stevia; pure creatine is just creatine.
Who it is for
Adults. Pregnant or nursing, under 18, taking medication, or managing a condition: talk to your doctor first. Each product lists its own cautions.
California
Products shipped to California carry a Proposition 65 notice where required.

Week one. Nothing to feel yet, and we would rather say so. A little scale weight from creatine is water, and temporary.

Month one. Creatine stores are full. Magnesium and the probiotic have been going in every day. You have a routine, which was the missing part.

Month three. This is a maintenance routine: it covers common gaps and keeps the habit going. It is not a source of extra energy.

Straight answers, including the ones that do not sell anything.

Is this for women too?

Yes. Nothing in the range is gendered. Collagen and the probiotic are the two products women buy most; creatine is one of the fastest-growing supplements among women; magnesium and D3 are for everyone. Pregnant or breastfeeding: talk to your doctor first, and skip the creatine drink.

Will I feel anything?

Probably not quickly, and we would rather tell you that than pretend. Creatine takes about four weeks to saturate, magnesium's sleep effect in trials is small, collagen's skin trials run 8 to 12 weeks. Every routine page has an honest week-one, month-one, month-three line.

Where is it made?

In facilities that follow FDA current Good Manufacturing Practices (cGMP), and every order ships from within the US. Every ingredient and amount is printed on the label and on this page, so you can check exactly what you are taking.

Can I buy just one product?

Yes, as a one-off order: $5.95 US shipping, free on orders over $50. Subscriptions come as routines, which is where the monthly savings and free shipping are.

How does the subscription work?

Pick a routine and it arrives as one box a month. We email you 3 days before every charge, so there is always time to change your mind. From your account you can skip a month, pause, or cancel in a click: no calls, no retention offers, no tricks. Want a different routine? Start the new one and cancel the old one in the same place. We will also tell you 30 days ahead if a price ever changes.

Can I take all five together?

Yes, for a healthy adult. Creatine and collagen in a morning drink, the probiotic and D3 with breakfast, magnesium before bed. Total supplemental magnesium across two products stays under the daily upper limit, so do not double-scoop. The same goes for vitamin D and calcium: D3 + K2 already gives 5,000 IU and 210 mg a day, so do not add another supplement with either. If you take prescription medication, especially blood thinners, check with your pharmacist first.

Do you ship outside the US?

Not yet. Compound Y is US-only while we get the basics right.
