Product name: Andalin (S-4) powder CAS Number: 401900-40-1 Molecular formula: C17H27Cl2N Chemical name: (2S)-3-(4-Acetylaminophenoxy)-2-hydroxy-2-methyl-N-(4-nitro-3-trifluoromethyl-phenyl)-propionamide Synonyms: Andarine, Andarin, S-4, S-40503, GTx-007 Molecular weight: 316.31 Melting point: 190-200°C Storage temperature: indoor temperature Color: light yellow fine powder Solubility: propylene glycol, DMSO, ethanol, PEG400 Physical form: solid1. As said earlier, SARMS function by tying to the AR resulting to anabolic activity. Due to this fastening and stimulation, more protein is produced which allows muscle building. S4 can trigger muscle development in the same way as steroids, but minus the same unwanted side effects, the latter has on the prostate and other sexual organs. 2. How it’s used depends on what effects you’re looking after. Fat elimination or cutting is the most effective use for S4 Andarine. 3. Right Dosing.Recommended dose for cutting is 50 mg for 6-8 weeks. You should use it every day then take 2 days off for the duration. Taking S4 daily for the length of the cycle can lead to changes in eyesight.Right Dosing : S-4 should be taken at 50mg-75mg, 5 days out of the week, for 12-16 weeks. As mentioned before, S-4 does not need to be taken on 3 separate occasions throughout the day; but for individuals that prefer this method, a 25mg dose (roughly half a milliliter) is recommended once with each of your three main meals. >>.Uses of Andarine * For Cutting (best use of S4) Andarine’s properties are very alike with steroids Anavar and Winstrol, the only difference is that S4 can better provide lean muscle gains. Recommended Dosage: 50 mg for 6-8 weeks. Take 2 days off when taking S4 (repeat the cycle after the 2 day break) to avoid vision side effects. *For Recomping Use S4 with a more anabolic SARM such as Ostarine for better recomp results as you’re aiming to gain muscle while losing fat. Recommended intake is 50-75 mg for 4 to 8 weeks. * For Bulking : S-4 isn’t the sarm that comes to mind when we think “BULKING”, but it’s properties in muscle gain shouldn’t be overlooked. S-4 can provide relatively large muscle gains and utilize these excess calories to provide an extra 8-10 lbs in muscle while also keeping the body relatively lean. This steady increase in muscle mass can limit the amount of work one needs to do for a leaner summer body.| Test Item | Analysis Specification | Result |
