Our story

Where others cut corners, we run the tests.

Our catalog is built around the peptides getting the most attention in current research across areas including metabolic function, cellular repair, inflammatory response, sleep regulation, and tissue recovery.

We don’t cut corners on sourcing. We don’t make clinical claims. We let the science speak.

TLC Renew, research-grade peptides for serious inquiry.

What we stand for

The commitments behind every vial

Every decision at TLC Renew runs through the same filter: does it hold up when a researcher checks the data?

Verifiable purity

We publish HPLC and mass-spec results for every lot. Not a marketing number but an actual chromatogram you can read and match to your vial.

Independent testing

Our labs have no commercial tie to us. If a batch doesn’t meet spec, it’s rejected. No exceptions, no quiet re-labeling.

Radical transparency

Lot lookup, batch data, sourcing, storage guidance. It’s all documented. We’d rather over-explain than leave you guessing.

Real human support

Knowledgeable, U.S.-based people who can answer storage, documentation and lot questions. Not a chatbot reading a script.

Handled with care

Cold-chain packing keeps lyophilized material stable in transit, so what reaches your bench matches what left our facility.

Strictly research use

Our products go to qualified professionals aged 21 or over for laboratory research, and we’re upfront about it from start to finish.
