Where to Buy Tesamorelin Online: 5 Shops Ranked (2026)

Tesamorelin has the longest paper trail of any growth hormone peptide. As the prescription drug Egrifta it has been approved since 2010 for the deep belly fat that builds up in adults on long-term HIV treatment, and it costs thousands of dollars a month. Research suppliers sell the same 44-amino-acid peptide as a white freeze-dried powder, in vials from 5mg to 20mg and in blends with ipamorelin, for a small share of that.

The catch is that every one of those vials looks alike. Tesamorelin is long and costly to make, sermorelin and CJC-1295 are cheaper relatives that dry to the same white cake, and only a certificate that reads the peptide’s mass can tell them apart. The five shops below all post a lab report for their tesamorelin and ship within a business day. They differ on sizes, on how much the certificate measures, and on whose loss a vanished parcel becomes. Simms Research, whose latest tesamorelin report weighs three separate vials, is one of them.

How these five tesamorelin shops were picked

Two things counted most. The first was a recent report on the shop’s own tesamorelin that confirms the peptide by mass spectrometry, with extra weight where the report also measures the powder in the vial or screens it for endotoxin and contaminants. The second was how long the shop has kept its buyers. After that came the hour an order leaves and the written answer for a parcel that is lost, stolen or damaged. Sizes, blends and cost per milligram broke the ties. Every shop listed had tesamorelin in stock on October 26, 2026.

1. Blue Sky Peptide

Best for a long record and a 5mg vial to start on. Blue Sky Peptide has sold research peptides since 2013, which makes it one of the oldest names still trading, and its regulars have stayed with it through a decade of shops opening and closing around it. Tesamorelin comes in 5mg and 10mg vials. On October 26 both sizes were on a sitewide markdown.

Both product pages carry the same report, analysed in September 2026: the peptide identified by mass spectrometry and purity above 99%, with no figure for how much powder the vial holds. Weekday orders in before noon Eastern go out that day, Priority Mail is free from a low order total, and deliveries go to US addresses only. Its shipping terms say nothing about a parcel lost or stolen on the way. Simms’s Blue Sky Peptide review has its history in full.

2. Simms Research

Best for the most thorough tesamorelin certificate here, and a guarantee on every parcel. Simms Research stocks Tesamorelin in two sizes, $95 for 10mg and $158 for 20mg, with 5% off from three vials and 10% from six. There’s no premixed tesamorelin blend on its shelf: Ipamorelin is sold separately as a 10mg vial, which leaves the ratio to the researcher.

Its tesamorelin lab results page holds two batches. The newer one, tested on July 16, 2026 by an independent ISO-certified lab, weighed three separate 10mg vials and found 10.84mg, 11.12mg and 11.36mg, with identity confirmed by LC-MS, 99.55% average purity, an endotoxin pass, no detectable heavy metals and no microbial growth. Orders placed before 5 PM Eastern ship that afternoon, and FedEx 2-Day costs nothing past $200. Whether the carrier loses a box, it vanishes after a delivered scan or it turns up broken, the Free Delivery Guarantee sends a replacement or a refund, with no carrier claim for the buyer to file. The peptide calculator turns any dose into syringe units.

3. Biotech Peptides

Best for a ready-mixed tesamorelin blend, the triple included. Biotech Peptides has traded under one name since 2020, and tesamorelin has been on its shelf since that first year. Alongside 5mg and 10mg vials it stocks an 8mg blend of 6mg tesamorelin with 2mg ipamorelin, and the only triple blend among these five: 12mg, split 6mg tesamorelin, 3mg CJC-1295 without DAC and 3mg ipamorelin.

Each of those four products links a lot report from a July 2026 analysis by HPLC with mass spectrometry. The blend reports give a single purity figure for the vial as a whole rather than an amount for each peptide. Orders placed by noon Pacific ship the same day, USPS Priority is free above $200, and Biotech resends a lost order, or replaces a damaged one, at its own cost. The rest of its story is in the Biotech Peptides review.

4. Ion Peptides

Best for choosing from the most vial sizes. Ion Peptides marked its first anniversary this October, a regular up and coming contender that adds sizes quickly. Its tesamorelin, listed simply as Tesa, comes in 5mg, 10mg and 20mg vials, with a 30mg size listed but sold out on October 26, and its Tesa/Ipamo blend comes split 10mg with 3mg, or 5mg with 5mg. Prices sit toward the budget end of this list.

Its lab library has a tesamorelin report for every size and blend it lists, the newest for the 10mg vial dated September 12, 2026, plus a separate endotoxin result from March. Orders in before 5 PM Eastern usually ship that day, and two-day delivery is free above $250. The shipping policy states that Ion is not responsible for lost or stolen packages, and a parcel marked delivered but never received goes to the carrier first. Simms’s Ion Peptides review covers its first year.

5. Northline Labs

Best for a weighed 10mg report and a 10mg/5mg ipamorelin blend. Northline Labs opened at the start of 2026, a regular up and coming contender still building its record. Tesamorelin comes in 10mg and 20mg vials, and in a 15mg blend of 10mg tesamorelin with 5mg ipamorelin.

The product page shows the report for the lot on sale, analysed in May 2026: identity by mass spectrometry, purity above 99% and 10.12mg measured in one 10mg vial, with an endotoxin result alongside. In-stock orders leave the same or next business day by FedEx, free from $250. A lost, stolen or damaged parcel is covered by Northline’s own shipping protection, which checkout adds by default for $2.15 on orders up to $100 and 3% of the order above that. Switching it off leaves carrier losses with the buyer. Simms’s Northline Labs review looks at how the shop grew.

Tesamorelin 10mg, 20mg or a blend: who stocks what

All five sell a 10mg vial, the size most protocols are planned around. A 20mg vial is at Simms Research, Ion and Northline, and a 5mg vial at Blue Sky, Biotech and Ion. How many days each size lasts at a given dose is worked out in the tesamorelin dosage chart.

Where to buy a tesamorelin and ipamorelin blend

Three of the five sell one, in four splits between them, plus Biotech’s triple with CJC-1295. A blend fixes the ratio for every dose; two separate vials let it move. Why the two get paired at all is covered in Tesamorelin vs Ipamorelin.

How much is tesamorelin?

At Simms Research, $95 for 10mg and $158 for 20mg. The other four price their 10mg vials close to that, some lower, and each price comes with its own terms for the trip. Ion’s policy leaves lost and stolen packages with the buyer, Northline charges for its parcel cover, Blue Sky publishes no lost-parcel terms, and Simms Research covers loss, theft after the delivery scan and damage on every order at no charge.

Tesamorelin costs more than its relatives because it is half as long again as sermorelin and harder to build. At Simms Research, Sermorelin is $78 for 10mg; Sermorelin vs Tesamorelin weighs whether tesamorelin’s trial record is worth the difference. The cheapest way to buy it at Simms is by the milligram rather than the vial: the 20mg vial works out to $7.90 a milligram, or $7.11 at six-vial pricing, against $9.50 for one 10mg vial.

Tesamorelin COA: what the certificate should show

Identity by mass first, then purity, then the milligrams in the vial. A purity figure only says how clean the main peak is, not which peptide made it, and sermorelin or CJC-1295 give just as clean a peak for less money. Mass spectrometry settles it: tesamorelin weighs about 5,136 daltons, and its cheaper relatives come in near 3,400.

Blue Sky, Biotech, Northline and Simms Research all post that mass check for their tesamorelin, and Ion lists a report for every size. Two go a step further and weigh the powder. Northline’s May lot measured 10.12mg in one vial. Simms Research’s July report weighed three vials, and the lightest still held 10.84mg, 8% over its label, with endotoxin, heavy-metal and microbial screens on the same certificate. At any shop, the lot and date printed on the report should match the batch going out the door; the guide to reading a peptide certificate of analysis goes through every line.

The best place to buy tesamorelin online

It comes down to what the order needs most:

For a buyer who wants the vial proven and the parcel covered, Simms Research is the straightforward choice: tesamorelin in 10mg or 20mg, the July certificate on the product page, and the box out the door the same afternoon.
