Where to Buy MOTS-c: 10,000 mcg at $3.75 per mg

Read the last column first. It is the one that decides whether a channel can be compared with any other channel, and three of the five fail it outright.

Three channels cannot produce a cost per milligram, which on this site is close to saying they cannot be evaluated. That is not a rhetorical point. If a seller will not publish the milligram content of what it ships, there is no denominator, and without a denominator every price comparison is guesswork dressed as research.

This is where the compound actually lives. A research supplier buys or commissions synthesised peptide, has batches assayed, fills lyophilised vials, labels them for laboratory use and ships domestically. Nothing about that arrangement is a loophole; it is the ordinary trade in research reagents, and the not-for-human-consumption labelling is the condition that makes the sale lawful in the United States rather than a wink at the buyer.

What separates suppliers inside this channel is documentation, not marketing. Ascension Peptides publishes two third-party certificates per MOTS-c batch, from Kovera Labs (batch 24-05260628) and MZ Biolabs (batch 24-01260229), and states same-day dispatch on orders placed before 2pm CST from US stock. Those are checkable claims: a batch code either matches your vial or it does not, and a dispatch cut-off either exists or it does not.

The commercial shape here is unusual for a peptide. MOTS-c is sold in one size, a 10 mg lyophilised vial, so there is no larger-vial discount to hunt. List is $75.00, the code PEPTIDEDECK takes it to $37.50, and that is $3.75 per mg. Quantity is the only other axis: 3, 5 or 10 vials take 3%, 5% or 10% off the list price, which works out at $7.28, $7.13 and $6.75 per mg respectively, all of them well above what the code does to a single vial. The tiers are not documented as stacking with the code, so treat them as alternatives and read the cart total.

Bulk peptide listings on international marketplaces advertise the lowest headline figures in this market, and the headline is the only part of the transaction you can see before you commit. Four things are usually missing.

• A batch certificate tied to your vial. Generic certificates circulate freely and cover nothing you were sent.
• A defensible strength. Milligram content is a claim on a listing until an outside laboratory says otherwise.
• Landed cost. Import duty, VAT in the UK and EU, and a courier handling fee are charged on delivery, after you have paid. They are part of what the material cost you and they belong in the per-milligram figure.
• Recourse. A parcel held or destroyed at a border is not usually refundable, and a marketplace dispute across jurisdictions is slow at best.

Buying research peptides is lawful in the United States when they are sold and bought as research material. Importing unapproved material into the UK or EU carries genuine customs and regulatory risk, and that risk sits with the buyer. This page will not tell you how to reduce the chance of a shipment being examined, because that is not advice worth giving and not advice we would give.

Searches for where to buy MOTS-c peptides bring this channel up constantly, usually with a per-gram price that looks unanswerable. Convert it to a landed cost per milligram before you believe it.

A reseller does not manufacture, commission or assay anything. It buys finished vials, or sometimes bulk powder, and moves them on through a storefront, a forum account or a messaging app. The material may well have started at a legitimate supplier. The problem is that nothing between that supplier and you is documented.

Three signals mark the channel. First, the certificate offered is the original manufacturer's, with a batch code that does not match the vial being sold. Second, the vial has been relabelled, decanted or repackaged, which breaks the only link between the certificate and the contents. Third, payment is arranged off-platform, which removes the chargeback route that a card payment normally gives you.

Price here is often lower than a domestic supplier's, and it should be, because the reseller carries no testing cost. If you cannot establish what is in a vial, a lower cost per milligram is not a saving; it is a smaller amount of money spent on an unknown. That is the same argument our best MOTS-c source page makes when it scores suppliers on published evidence rather than on price alone.

Compounding pharmacies cannot supply MOTS-c. A 503A pharmacy may compound from a bulk drug substance only where that substance has a USP or NF monograph, is a component of an FDA-approved drug, or appears on the FDA's 503A bulks list. MOTS-c satisfies none of the three. There is also no approved MOTS-c product to compound from, which is the more basic obstacle. A pharmacy offering it is not operating inside the framework the FDA sets out for compounding.

Longevity and wellness clinics cannot prescribe it either, because there is nothing to prescribe. What clinics in this space do sell is adjacent: NAD+ infusions, vitamin drips, mitochondrial support programmes, metabolic panels. Those are real services with their own pricing, and none of them is MOTS-c. Where a clinic does advertise MOTS-c specifically, the material is coming from the same research-supply channel described above, with a consultation fee on top and usually without the batch certificate being shown to you.

The practical consequence is that the clinic route inverts the unit. A supplier sells you 10 mg and you divide. A clinic sells you an appointment, and the milligram content of anything involved is not on the invoice. Our sibling page on MOTS-c near me takes the local-search version of this question apart in more detail.

Every channel quotes a different unit. A supplier quotes a vial, a marketplace quotes a gram, a reseller quotes whatever is in front of them and a clinic quotes an hour. One conversion puts them on the same axis.

Divide the total you paid by the milligrams you received. For the offer on this page that is $37.50 divided by 10 mg, or $3.75 per mg. At the list price it is $7.50 per mg. Add carriage if your order is under the $250 free-shipping threshold, which a single $37.50 vial plainly is; you would need seven vials, $262.50, to clear it. For an overseas order, add duty, VAT and the courier handling fee before dividing, because those are part of the cost of the material even though they arrive later.

From dollars per mg to dollars per draw

The second conversion turns price into something you can see on a barrel. A 10 mg vial is 10,000 mcg. Reconstituted with 2 mL of bacteriostatic water it is 5 mg/mL, so the vial holds 200 units of a U-100 syringe and a 10 unit draw is 500 mcg. At $37.50 that is roughly $0.19 per unit and $1.88 per 500 mcg. Reconstitute the same vial with 1 mL and it is 10 mg/mL across 100 units, so 10 units is 1 mg. The vial is the same; only the arithmetic moved. Work it through with our reconstitution guide, the syringe measurement guide and the calculator. All of it is laboratory handling arithmetic, not a protocol for anyone to follow.
