Changelog: What's New

2026-07-13

Improved Smarter membership costs on Labs: Fitomics pricing is corrected to its real signup terms, and the ranking now charges whichever billing option is cheapest for how often you test (one month on the monthly plan for a one-off order, or your share of the annual plan if you test a lot). There's also a new "I already have a membership" checkbox that drops the fee from the ranking, since existing members have already paid it.
New A Fees & fine print page for Labs: every order site's blood-draw fee, membership, minimum order, coupons, and state limits spelled out side by side, so the charges that don't show in a per-test price are easy to see.
New You can now help keep Labs accurate: expand any order site and click "flag" to report a price that looks wrong, or use "Suggest an order site" to tell us about a lab we're missing. Both go straight to us for review.

New Big Labs update. Every result now expands to show each test's price with a direct link to order it on the vendor's site. Your basket and settings are remembered between visits. The split-order optimizer gained controls for the most sites you'll visit and the least each extra site must save. There's a ZIP box that links you to LabCorp, Quest, and BioReference draw-site finders, plain-language descriptions on every test, and a dedicated price page for each of the 68 tests (for example, the TSH page).

New A Blood Test Price Tracker: price history for every test at every order site, re-checked weekly. See recent price changes with deltas, chart one test across sites over time, or view one site's full change table, and download the raw history as CSV.
New Labs updates: the "Prices as of" line now opens a per-site update status (when each order site's prices were last verified, pass/fail, and how many tests are live-priced), and the full price matrix (every site × every test, always current) is downloadable as Excel or CSV from the same overlay. The lab-set CSV export gained a price column per test and the full fee math.
New A Blood Test Price Comparison tool: pick the blood tests you want (or start from a preset panel) and see what your set actually costs at 15+ self-pay order sites, including each site's draw fee, membership pricing, minimum orders, and coupons. It shows which performing lab (LabCorp, Quest, BioReference) runs each order, a membership break-even, and a split-order optimizer that finds the cheapest way to buy across more than one site. Built from community member PedroDaGr8's price research, with his blessing.

New A Smart Reconstitution Optimizer: enter your vial size and dose, and it recommends how much BAC water to add so your syringe draw lands on a clean, round number. Recipes are ranked by easiest to read and smallest injection volume, with per-compound presets, and each one opens in the full calculator with a single tap. The same engine now powers an "Optimize for me" toggle on the Reverse calculator, which picks the draw for you instead of asking for one.

New An Injection-Site Rotation Map: a front and back body map where each tap logs an injection at that site, every site recolors by how long it has rested, and the longest-rested site is recommended next so the same tissue is not used twice in a row. A cadence note warns when your schedule cycles back to a site faster than it can recover. Everything is saved in your browser, with JSON, CSV, and share-link export.
New A Reconstitution Reference Chart: pick a compound to load its typical vial sizes and dosing schedule, and every cell shows how much BAC water to add and the resulting U-100 syringe draw. It covers the common GLP-1 and incretin peptides with their name-brand titration steps (such as tirzepatide and semaglutide) plus a range of research peptides, and you can switch between easier-to-read and smaller-volume draws. Type your own vial size or dose into the blank row and column for anything not listed, and tap any cell to open it in the full calculator with the values filled in.

New The Runway calculator: enter how much peptide, oil, or oral supply you have on hand plus your dose and schedule to see how long it lasts and when it runs out. A titration table shows how raising or lowering the dose changes your runway, and you can export everything to Excel or Google Sheets with the formulas intact.

New A "Total Number of Doses in Vial" readout below the syringe guide on the Calc, Reverse, and HGH calculators, showing how many full doses a vial yields at your current dose.

New A visual syringe guide on the Calc, Reverse, Blend, and HGH calculators: a full-syringe overview plus a zoomed, unit-by-unit view showing exactly where to draw.
Improved In the Blend calculator, the syringe draw guide now sits below the per-dose table, so you confirm the per-peptide amounts first and then see where to draw.

New Named-blend calculators for GLOW, KLOW, and Wolverine, each with a dedicated page, a pre-loaded calculator, and dosing plus reconstitution notes.
New Pre-blended vial mode in the Blend calculator: reconstitute and dose a single pre-mixed vial directly, with no multi-vial transfer steps.
New A peptide glossary in the research library, with key terms auto-linked throughout the research articles.
Improved Quick-load presets for common blends in the Blend calculator. Pick GLOW, KLOW, or Wolverine and it fills the calculator in whichever mode you're using, highlights the selected blend, and the pre-blended / mix-your-own switch is clearer.
Improved The Reverse calculator now frames its result around smart reconstitution for a clean syringe draw. Wording and metadata only; the math is unchanged.

Improved All calculators now live under a single address at www.peprecon.com (for example /calc, /reverse, and /blend). Older subdomain bookmarks redirect automatically, so existing links keep working.

New The Peptide Planner now supports stacking multiple peptides and blends in one titration schedule, with a combined dose and concentration timeline.

New The COA Reader: upload a certificate of analysis to get an extracted, checked summary, with links to verify the results against the testing lab.
