How Much Does Tesamorelin Cost? Peptide Pricing in 2026

Tesamorelin cost comes down to one listed size: $115 for a 10 mg vial, or $11.50/mg, prices as of September 2026 from the HEEZ catalog. At the 2 mg daily quantity used in the published trials (PMID 38905488), a vial covers five days, so 30 days of material is 6 vials at $690 and the 26-week window used in the phase III program (PMID 36845310) is 37 vials at $4,255. With a single size catalogued there is no per-mg spread to shop. Duration and analytical coverage move the number instead.

What does tesamorelin cost per mg?

One size is listed, so the per-mg rate is a division rather than a choice. The figures below come from tesamorelin price at HEEZ Research, prices as of September 2026 from the HEEZ catalog.

Size	Price	Price per mg
10 mg	$115	$11.50/mg

Table 1: HEEZ Research tesamorelin size with cost per mg derived from it. Price per mg = price ÷ size in mg, so $115 ÷ 10 mg = $11.50/mg. Prices as of September 2026 from the HEEZ catalog.

That column is a rate for continuous material, and vials are sold as whole units. The rate only describes what you actually pay when the quantity you need divides evenly into 10 mg, which at the 2 mg trial quantity it does. Vial-size arbitrage, where a larger tier posts a lower rate until whole-vial rounding reverses it, requires a catalog with more than one size, as the retatrutide per-mg tiers have.

What does tesamorelin cost per month?

Six vials, $690, for a 30-day window at 2 mg daily. The same arithmetic applied to the durations in the published record gives the figures below.

Window	Days at 2 mg/day	Total (mg)	Vials (10 mg)	Cost
30 days	30	60	6	$690
24 weeks (TRIUMPH protocol, PMID 42419889)	168	336	34	$3,910
26 weeks (phase III window, PMID 36845310)	182	364	37	$4,255
52 weeks (extension phase, PMID 22050344)	364	728	73	$8,395

Table 2: material cost for each published study window at the 2 mg daily quantity (PMID 38905488), computed from the Table 1 catalog price. Days = weeks × 7; total mg = days × 2; vials = total mg ÷ 10 rounded up to the next whole vial; cost = vials × $115. Prices as of September 2026 from the HEEZ catalog.

Only the 30-day row divides exactly. The 26-week row needs 364 ÷ 10 = 36.4 vials and rounds to 37, stranding 370 − 364 = 6 mg worth 6 × $11.50 = $69, and the 52-week row strands 730 − 728 = 2 mg worth $23.

The five-days-per-vial figure assumes full recovery of the solid. Reconstituted with 2 mL of bacteriostatic water, a 10 mg vial sits at 10 ÷ 2 = 5 mg/mL, so a 2 mg withdrawal is 2 ÷ 5 = 0.4 mL, which reads as 40 units on a U-100 syringe at 1 mL = 100 units. Five withdrawals of 0.4 mL consume the full 2.0 mL with nothing in reserve, so transfer and hub losses across a 30-day window surface as a seventh vial at $115 rather than as a rounding error.

What is the price actually buying over those windows?

The durations in Table 2 are not arbitrary lengths. Each one is a window over which tesamorelin was measured against a comparator, and the endpoints that separated differ from the ones that did not.

Study (PMID)	n	Duration	Reported result
Randomized double-blind vs placebo, MASLD subgroup on integrase inhibitors (38905488)	38 of 61 enrolled	12 months	Visceral fat −25 cm² (IQR −93, −2) vs +14 (3, 41), P = 0.001; hepatic fat −4.2% vs −0.5%, P = 0.01
Phase 2 open-label vs standard of care (39813152)	73 randomized 3:2	6 months	Between-group neurocognitive difference not significant (P = .673); waist circumference median difference −2.7 cm, P = .015
Phase III post hoc by dorsocervical fat (36845310)	not stated	26 weeks	Visceral fat and waist circumference reductions did not differ between fat groups (P = 0.657 and P = 0.093)

Table 3: endpoints reported at each study duration, all at 2 mg daily where the amount was stated (PMID 38905488, PMID 39813152). Source PMIDs in the first column.

Body-composition endpoints moved in both controlled comparisons; the neurocognitive endpoint in the 6-month open-label trial did not separate from standard of care despite a within-group trend of 0.146 (95% CI −0.002 to 0.294, P = .060), which the authors attributed in part to insufficient power and the absence of a placebo arm (PMID 39813152). Duration also carries a reversion term: visceral fat reductions held to week 52 in the extension phases of the two 26-week trials, while discontinuation during that period was followed by reaccumulation (PMID 22050344).

A 24-week window is currently being studied with an exercise programme attached, in a two-site double-blind trial of 100 sedentary adults aged 50 to 80, followed by a 24-week independent exercise extension (PMID 42419889, NCT06554717). That protocol has no results yet, so the 24-week row in Table 2 is a material figure for an open question rather than a measured one.

What drives the price of a tesamorelin vial?

Analytical depth, purification, and how much of the labeled solid is peptide. None of the three appear as line items, so two vials marked 10 mg at the same price can be different purchases.

Start with what the certificate of analysis is keyed to. A certificate naming only the compound tells you a product line was tested at some point. A certificate carrying the batch number printed on your vial tells you that lot was tested, and per-lot testing costs the seller real money, which is part of what any given price includes.

Purity and identity are separate measurements. High-performance liquid chromatography returns area percent, the share of detected material that is one dominant species, and says nothing about which species it is. Mass spectrometry answers that by comparing observed mass against the theoretical mass of the sequence. Tesamorelin is a synthetic analog of growth hormone-releasing hormone (PMID 22050344), and a chain of that length accumulates deletion and truncation byproducts close enough in structure that separating them is the expensive step. A lower price more often reflects a shorter purification than a cheaper synthesis.

Then check whether net peptide content is reported at all. Lyophilized material carries counterion, residual solvent and water alongside peptide, so the labeled figure is solid mass. A 10 mg vial at 90% net peptide holds 10 × 0.90 = 9 mg, and the real rate becomes $115 ÷ 9 = $12.78/mg instead of $11.50/mg, an 11.1% increase that no purity percentage discloses. When the figure is absent, read the per-mg column as a ceiling on value rather than a measurement of it. The order to check those certificate fields in, and what each one cannot tell you, is set out in a seven-point COA read.

Is there a prescription or insurance price for tesamorelin?

Tesamorelin is the only FDA-approved therapy for abdominal fat accumulation in people with HIV (PMID 38905488), which separates it from most compounds sold on research catalogs. An approval means a labeled indication exists, and with it a pharmacy channel and a payer channel.

Those channels do not produce the figure on this page. A catalog price is for research material supplied by the unit; a pharmacy or insured price attaches to a dispensed, labeled product and is set by payers and manufacturers. Putting the two side by side compares distribution channels rather than compounds, which is why no insured or cash pharmacy figure appears in Table 1 or Table 2. Why a compound can sit on an approved-drug list and a research catalog at the same time, and why published approval lists disagree with each other, is worked through in why approved peptide lists differ.

Common questions about tesamorelin cost

Do you need a prescription for research tesamorelin? It is not dispensed against a prescription. The catalog channel supplies qualified organizations for research use only, which is a supply restriction rather than a clinical one.

What is the tesamorelin price in the USA? The $115 figure is the domestic landed price before shipping. HEEZ Research ships same day by UPS from Florida on orders placed before the 3 PM ET cutoff, at ambient temperature, so lyophilized material carries no cold-chain surcharge on top of the vial price.

Can a tesamorelin order be returned if the cost was a mistake? No. All sales are final.

Does the price include analytical testing? Yes on this listing. Every lot carries a batch-specific third-party certificate of analysis covering HPLC purity and MS identity, with purity stated as ≥99% as measured, rather than testing being priced as a separate line item.
