TirzepatideDual agonistResearch Only
02 / 03

Tirzepatide 40 mg

LY3298176. Co-activates GIP and GLP-1 receptors — a reference compound for dual-agonism pharmacology and signalling studies.

£199.00View details
SemaglutideSingle agonistResearch Only
03 / 03

Semaglutide 8 mg

GLP-1 receptor agonist. Well-characterised reference for in-vitro receptor binding, signalling and structure-function work.

£99.00View details
03 / THE ADAPTOG STANDARD

Every batch is documented,
verified, and traceable.

HPLC / LC-MS verified

Identity and purity confirmed in every batch by independent analytical methods and archived for reference.

CoA with every order

Batch-matched certificates of analysis — lot number, identity, purity, storage — delivered with the shipment.

Money-back guarantee

If materials don't match the documentation we send, we refund — no friction, no minimums.

Responsive lab support

Direct access to our research team for CoA interpretation, storage guidance and compound stability queries.

04 / FROM THE JOURNAL

Science, in context.

Structured summaries of recent peer-reviewed work in GLP-1 pharmacology and metabolic research — published to support, not guide, your investigation.

GLP-1 Receptor Agonists and Muscle Mass: Balancing Weight Loss and Lean Tissue Preservation

A 2025 review in Pharmacological Research explores metabolic benefits and lean mass changes during GLP-1 RA therapy. Findings suggest monitoring of vulnerable populations and adjunct strategies including resistance training and protein intake may mitigate lean tissue loss.

Semaglutide vs Tirzepatide: A Meta-Analysis of 56 Trials

The 2025 Nature Medicine network meta-analysis of 60,000+ participants identified both compounds as the only medications achieving >10% total body weight loss. Distinct profiles emerge in cardiovascular outcomes, HbA1c reduction, and downstream indications.
