TB-500 Nasal Spray Price Comparison — Verified Vendors & Lab-Tested COAs

How much does TB-500 Nasal Spray cost per month?

The cheapest verified TB-500 Nasal Spray protocol works out to about $24.56 per month: Glow Aminos's 30 mg bottle at $85.09 with code WPA, dosed at 2 mg once weekly (the most-common community protocol). One bottle provides 15.0 doses — about 15.0 weeks of supply at this cadence — so the per-week cost is roughly $5.67, which works out to $24.56 on a 4.33-week month. This protocol is derived from 3,342 verified TB-500 calculator runs logged by the WPA community. Cost scales roughly linearly with the per-spray dose and weekly frequency you choose.

Use the live cost-per-month card directly above the vendor table to switch between bottle size, per-spray dose, weekly frequency, and vendor strategy (cheapest cost per month across all vendors and bottle sizes, or highest-quality vendor by verified COA purity).

TB-500 Nasal Spray is stocked in 2 sizes: 10mg and 30mg bottles. Because bottles of different strengths rarely scale linearly in price, the per-milligram column is the only fair way to rank them.

Ranked by true cost per milligram, the TB-500 Nasal Spray listings WPA tracks are: Glow Aminos — 30mg at $85.09 ($2.84/mg), COA purity 98.00%; Flawless Compounds — 30mg at $85.09 ($2.84/mg), COA purity 98.00%; Modified Aminos — 30mg at $116.99 ($3.90/mg); LA Peptides — 10mg at $53.99 ($5.40/mg).

TB-500 Nasal Spray COA Coverage Across Tracked Vendors

3 of the 4 tracked TB-500 Nasal Spray listings (75%) publish a third-party Certificate of Analysis. Assayed purity on those reports is 98.00%. 3 listings report more TB-500 in the bottle than the label claims, which lowers the real cost per milligram below the printed price. The most recent TB-500 Nasal Spray COA on file is dated 3/26. The remaining 1 listing has no published report, so its purity is the vendor's own claim.

A COA is only worth what it proves: it has to name the independent lab, be dated within the last 12 months, and match the exact TB-500 Nasal Spray batch and bottle size on sale. Open the linked report before ordering rather than trusting the badge.

How Researchers Actually Dose TB-500

Across 3,342 TB-500 calculator runs logged by the WPA community, the most common dose entered is 2mg, most often once weekly. The size researchers calculate against most often is the 10mg bottle (2,093 runs). The most common bacteriostatic water volume is 2mL, which is what sets the draw marks on the syringe for that dose. At that dose a 30mg bottle yields roughly 15 doses, so the bottle size you buy decides how often you reorder as much as the price does.

TB-500 Nasal Spray Discount Codes

4 of the 4 tracked TB-500 Nasal Spray listings carry a WPA researcher discount code. The largest live discount is 15% off. Every price and per-milligram figure on this page is the post-discount number, so you are never comparing a discounted listing against an undiscounted one. Codes change and some exclude sale items or carry order minimums.

About TB-500

TB-500 is one of the most-sourced research peptides for soft-tissue and recovery protocols, often stacked with BPC-157. It ships as a lyophilized powder you reconstitute with bacteriostatic water before use — but note that "TB-500" (a 17-amino-acid fragment) is frequently conflated with full-length thymosin beta-4.

Its reported half-life is ~2 days, which is the main reason the community cadence above looks the way it does. Not FDA-approved.

How to Read the TB-500 Nasal Spray Comparison

• Price per milligram — Every TB-500 Nasal Spray listing is normalized to $2.84/mg-style unit pricing, so a small cheap bottle cannot hide a worse real cost than a larger one.
• COA status and purity — The 3 COA-backed TB-500 Nasal Spray listings show assayed purity and test date so quality is a number, not a claim.
• Bottles sizes — All 2 stocked TB-500 Nasal Spray sizes (10mg and 30mg bottles) sit in one table.
• Stock status — Live in-stock state for each TB-500 Nasal Spray listing, refreshed on a recurring basis.

Reading TB-500 Nasal Spray Listings

Nasal spray listings are ranked on total TB-500 per bottle, so a lower-priced bottle at a lower concentration can still be the more expensive option per milligram. Where a vendor publishes it, the mcg or mg delivered per spray is what determines how many doses a bottle actually contains.

A nasal spray COA should confirm the active ingredient's purity, and — where available — the preservative system and pH range, which do not appear on a vial COA. Intranasal delivery differs from injection in absorption kinetics, so vial protocols do not carry over.
