How Much Does Reta Cost? A 2026 Price Breakdown

Buying Guide — 2026-05-26

"How much does reta cost?" is a fair pre-purchase question, but the sticker price on a vial only tells part of the story. What matters for research budgeting is cost *per milligram* and cost *per research dose* — and those depend heavily on vial size, purity, and batch testing. Here is how reta pricing actually breaks down.

Researcher special: code WELCOME at checkout unlocks 35% off Reta 10mg, Reta 20mg, the Metabolic Stack, and bacteriostatic water. Every vial ships with a batch-matched COA at 99%+ HPLC purity.

How Reta Is Priced

Reta is sold by total peptide mass per vial. The two common research sizes are 10mg and 20mg:

The 20mg vial almost always wins on cost-per-mg — you pay more up front but less per unit of peptide.

What Drives the Price

Reta is expensive to synthesize relative to simpler peptides, and a few factors move the number:

• Synthesis complexity — reta is a long, modified peptide and is harder to make cleanly
• Purity — pushing HPLC purity to 99%+ requires additional purification passes
• Batch testing — third-party COAs, mass-spec identity, and endotoxin testing add cost
• Sourcing and handling — US-based cold-chain handling costs more than drop-shipped material

Cost Per Milligram Is the Real Comparison

Two vials at different prices are only comparable on a per-mg basis. A 20mg vial at a higher sticker price is frequently cheaper per mg than a 10mg vial. When comparing vendors, divide price by total mg — not by vial. (See 10mg vs 20mg.)

Cost Per Research Dose

Reta research protocols typically run 2–12 mg per weekly administration. At a 4 mg research dose:

• A 10mg vial = 2.5 doses
• A 20mg vial = 5 doses

So a single 20mg vial can cover more than a month of a 4 mg weekly protocol. (Full dose math: how long a reta vial lasts.)

Do Not Forget the Consumables

Budget for the supporting materials too:

• Bacteriostatic water for reconstitution
• U-100 insulin syringes for accurate sub-mg measurement
• Alcohol prep pads for sterile handling

These are inexpensive but required for accurate, contamination-free research.

What Underpricing Signals

If reta is priced dramatically below the market, treat it as a warning, not a deal. Suspiciously cheap material often means:

• Under-dosed or impure peptide
• No real batch testing behind the COA
• Pre-reconstituted or degraded product

In endpoint-driven research, batch variation is a worse problem than a slightly higher price. Pay for documented purity.

Bottom Line

Reta pricing comes down to per-mg value and verified purity. The 20mg vial generally offers the best cost-per-mg, consumables add a small fixed cost, and unusually cheap material is a red flag. Compare on cost-per-mg with a COA in hand.

Code WELCOME at checkout unlocks 35% off Reta 10mg, Reta 20mg, the Metabolic Stack, and bacteriostatic water. Every vial ships with a batch-matched COA showing 99%+ HPLC purity — so the price you pay maps to the peptide you actually receive.
