Buy S-4 (Andarine) Capsules Online

Buy S-4 (andarine) capsules are a unit presentation of the nonsteroidal SARM also coded GTx-007. The copy below is for a product page. Capsule strength is labeled fill weight, not a dose. It does not include cycle advice or human-use claims.

Introduction

S-4 (andarine) capsules contain the nonsteroidal selective androgen receptor modulator (2S)-3-(4-acetamidophenoxy)-2-hydroxy-2-methyl-N-[4-nitro-3-(trifluoromethyl)phenyl]propanamide. It is an arylpropionamide related to enobosarm, with an acetamido ether on one ring and a nitro-trifluoromethyl aniline on the other. It is not a steroid.

Published descriptions class it as a partial agonist of the androgen receptor and an investigational SARM. It is not an approved medicine. Analytical suppliers list S-4 as a forensic reference because products sold as andarine have appeared in anti-doping and seized-supplement cases.

The milligram figure on the capsule is the declared amount of andarine per unit. It is not a recommended amount for any use. Excipients must be listed, because the capsule mass is not the same as the active content.

Key features and benefits – Buy S-4 (Andarine) Capsules

• Arylpropionamide SARM. The acetamide, nitro group, and CF3 distinguish it from ostarine, which has two nitriles and no nitro group, and from ligandrol.
• Unit fill. A capsule declares a fixed content, which supports uniformity checks without weighing bulk powder.
• Documented identity. CAS 401900-40-1, formula C19H18F3N3O6, molar mass 441.36 g·mol−1.
• Separable from excipients. HPLC assay can distinguish the active from fillers.
• Laboratory-only handling. Intended for controlled chemical and in vitro work, not for dietary or performance use.

Specifications Of Buy S-4 (Andarine) 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 andarine after extraction from the capsule fill.
• Forensic screening of products labeled as S-4 or andarine.
• Androgen-receptor binding or reporter assays where the protocol covers this compound and the excipients are accounted for.
• Comparison of capsule fill with bulk andarine of the same CAS.

Do not describe or imply oral use, stacking, 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 acetamide, the propionamide, and the CF3 group.
• Mass spectrometry for the molecular ion consistent with C19H18F3N3O6.
• Chiral check if the supplier claims the (S) enantiomer.
• 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 treat a racemic or unnamed isomer as andarine without that check.

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. Andarine is not an authorized medicine. SARMs are prohibited by the World Anti-Doping Agency at all times. Health authorities have warned of possible cardiovascular and liver risks from SARM-containing bodybuilding products. Legal status varies. 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 andarine, also called S-4 and GTx-007, a nonsteroidal SARM, formula C19H18F3N3O6. Fillers must be listed separately from the active.

What does the milligram label mean?
It is the declared amount of andarine per capsule. It is not a recommended dose. Confirm whether the figure is active content or total fill weight.

Is this the same as ostarine or ligandrol?
No. Ostarine (enobosarm) is CAS 841205-47-8 and has two nitrile groups. Ligandrol is LGD-4033, a pyrrolidinyl benzonitrile. Andarine is CAS 401900-40-1 and has an acetamide and a nitro group.

Which CAS number applies?
CAS 401900-40-1 for the active. Confirm the (S) configuration on the COA, not only the CAS.

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 SARMs. 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 C19H18F3N3O6. A chiral check is needed if the (S) enantiomer is claimed.
