If you were sourcing Retatrutide, Tirzepatide or Semaglutide from My Life Peptides, the hard part of replacing them is not finding another catalog — it is knowing that what arrives matches the label without taking a new supplier's word for it. Lyra Vital publishes an independent Janoshik Analytical certificate for every batch before you buy, including superseded batches, each carrying a laboratory key you can check yourself. There are 19 published certificates for Retatrutide alone.
My Life Peptides stopped trading in March 2026 (closure confirmed by Lyra Vital, 2026-09-30), leaving researchers to find a replacement mid-project.
What to look for in a replacement
The buyers who got burned when a vendor vanished tend to screen for the same things afterwards. Here is each, and how Lyra Vital answers it.
A certificate from a named third-party laboratory
Every batch is tested by Janoshik Analytical, named on every certificate — not “third-party tested” with no lab to check.
HPLC purity and mass-spec identity, together
Both are on each certificate: how much is the target compound, and confirmation the molecule is what the label claims.
Certificates you can see before you buy
37 compounds have their certificate published on the site right now — nothing held pending an email.
Evidence the quality holds across batches
162 certificates are on record across current and prior lots, each independently verifiable at the laboratory.
The difference, in one page
Anyone can say “lab tested.” We publish the laboratory, the batch, and the history.
Every certificate is issued by Janoshik Analytical, published before purchase, and verifiable with a secret key at the laboratory itself. Read exactly how it works, then check a batch yourself.
Questions
Is Lyra Vital a good My Life Peptides alternative?
My Life Peptides stopped trading in March 2026 (closure confirmed by Lyra Vital, 2026-09-30), leaving researchers to find a replacement mid-project. Lyra Vital is a US research-peptide supplier that publishes an independent Janoshik Analytical certificate for every batch, before purchase, each carrying a secret key you can verify with the laboratory directly. Materials are supplied strictly for laboratory research use.
How do I know the certificates are real?
Each certificate carries a secret key issued by the laboratory. Enter your vial's batch code on the Verify page to open its certificate, then check the key on Janoshik's verification page. If it resolves, it is genuine — the proof does not depend on trusting us.
Lyra Vital is newer than My Life Peptides was. Why switch?
Because the thing worth keeping was never the tenure — it was knowing what is in the vial. A long-running seller that will only show a COA on request proves less than a newer one that publishes every certificate up front. We compete on verifiable proof, from day one.
