GW-501516 (Cardarine) Capsules

Buy GW-501516 (Cardarine) Capsules Online

Buy GW-501516 (cardarine) capsules are a unit presentation of the PPARδ agonist also sold as endurobol. The copy below is for a product page. Capsule strength is labeled fill weight, not a dose. It does not include human-use claims. It is not a SARM.

Introduction

GW-501516 (cardarine) capsules contain 2-[2-methyl-4-[[4-methyl-2-[4-(trifluoromethyl)phenyl]-1,3-thiazol-5-yl]methylsulfanyl]phenoxy]acetic acid. It was invented in a collaboration between Ligand Pharmaceuticals and GlaxoSmithKline and is also coded GW1516 and GSK-516. Endurobol is another listing name. It is a selective agonist of peroxisome proliferator-activated receptor delta (PPARδ), not an androgen-receptor ligand and not a steroid.

Published binding data give a Ki of about 1 nM and an EC50 of about 1 nM at PPARδ, with greater than 1,000-fold selectivity over PPARα and PPARγ in the reported assays. Clinical development for metabolic disease was stopped. Long-term animal studies found tumors in multiple organs. It is not an approved medicine. The World Anti-Doping Agency prohibits it as a metabolic modulator.

The milligram figure on the capsule is the declared amount of GW-501516 per unit. It is not a recommended amount for any use. The label must state whether that figure is the free acid. Excipients must be listed, because the capsule mass is not the same as the active content.

Key features and benefits – Buy GW-501516 (Cardarine) Capsules

• PPARδ ligand. The thiazole, trifluoromethylphenyl, and phenoxyacetic acid distinguish it from SARMs and from REV-ERB agonists such as SR-9009.
• Unit fill. A capsule declares a fixed content, which supports uniformity checks without weighing bulk powder.
• Documented identity. CAS 317318-70-0, PubChem CID 9803963, formula C21H18F3NO3S2, molar mass 453.5 g·mol−1.
• Separable from excipients. HPLC assay can distinguish the free acid from fillers.
• Laboratory-only handling. Intended for controlled chemical and in vitro work, not for dietary or performance use.

Specifications Of Buy GW-501516 (Cardarine) Capsules

Applications in research

Appropriate uses are non-clinical and institutionally approved:

• Content-uniformity and assay checks on a labeled capsule strength.
• HPLC, LC-MS, and NMR identification of GW-501516 after extraction from the capsule fill.
• Forensic screening of products labeled cardarine, endurobol, or GW-501516.
• PPARδ assays where the protocol covers this compound and the excipients are accounted for.
• Comparison of capsule fill with bulk powder of the same CAS.

Do not describe or imply oral use or any human performance protocol. Do not treat the labeled milligrams as a dose.

Purity and testing

A defensible product claim rests on the batch certificate and an assay of the filled unit.

• HPLC of the extracted fill for chromatographic purity and for assayed content per capsule against the label.
• 1H NMR and 19F NMR, or LC-MS, for the phenoxyacetic acid, the thiazole methyl, and the CF3 group.
• Mass spectrometry for the molecular ion consistent with C21H18F3NO3S2.
• Confirmation that the active is the free acid, not a salt or a different PPAR ligand.
• Excipient list, and a check that fillers do not co-elute with the active.
• Content uniformity across units if the supplier states it.

Store the COA with the lot number. Do not use the deprecated CAS 813458-54-7 as the product number.

Disclaimer

For laboratory research use only. Not for human or veterinary consumption, not for diagnostic or therapeutic use, and not a food, drug, or dietary supplement. The capsule strength is fill weight, not a dosing instruction. GW-501516 is not an authorized medicine. Development was stopped after long-term animal studies found tumors in multiple organs. It is prohibited by the World Anti-Doping Agency. Australia has scheduled it as an illegal substance. Legal status varies elsewhere. Buyers are responsible for confirming legality, licensing, import rules, and institutional approval before ordering or handling. Handle with standard laboratory PPE and dispose of waste under local hazardous-chemical rules. No statement on this page is a claim of safety, efficacy, or fitness for any human application.

Frequently asked questions

What is in the capsule?
The active is GW-501516, also called cardarine and endurobol, a selective PPARδ agonist, formula C21H18F3NO3S2. It is not a SARM. Fillers must be listed separately from the active.

What does the milligram label mean?
It is the declared amount of GW-501516 per capsule. It is not a recommended dose. Confirm whether the figure is free-acid content or total fill weight.

Is this the same as SR-9009 or ostarine?
No. SR-9009 is a REV-ERB agonist. Ostarine is an androgen-receptor ligand. GW-501516 is CAS 317318-70-0 and acts at PPARδ.

Which CAS number applies?
CAS 317318-70-0 for the active. Do not use the deprecated number 813458-54-7.

How should capsules be stored?
Sealed, cool, dry, and protected from light. Keep the lot number with the COA.

Can they be used in humans?
No. They are not an approved drug or supplement and are not sold for consumption. Anti-doping rules prohibit GW-501516. Animal carcinogenicity findings are a reason it was not developed as a medicine. Check local law before purchase.

What analytical methods confirm identity?
HPLC assay of the extracted fill against the label, 1H and 19F NMR or LC-MS, and mass spectrometry consistent with C21H18F3NO3S2. The COA should state free acid if that is the filled form.
