Stenabolic SR-9009

Stenabolic is the common name for SR-9009, a Rev-erb agonist rather than a SARM or anabolic steroid. It works by activating Rev-erb proteins that regulate circadian rhythm and mitochondrial output, which is why users report better endurance and steadier fat burning. It does not bind androgen receptors, so it will not affect natural testosterone the way an oral steroid would.

As a guide, not medical advice, users commonly split 10mg capsules across two to three doses through the day rather than taking them all at once, since SR-9009 has a short half-life and needs frequent topping up to keep blood levels steady. Most runs described online sit in the 8 to 12 week range. Always start low and see how you respond before doing anything else.

Because it is non-hormonal, SR-9009 does not suppress natural hormone production, so a PCT is not typically needed after a run. Reported effects are mild and include occasional headache, nausea, or restlessness, and taking a dose too late in the day can disrupt sleep given its link to circadian rhythm. Anyone with existing liver, thyroid or metabolic issues should speak to a doctor before starting.

Both are aimed at endurance and fat loss but work through different pathways. Cardarine is a PPAR-delta agonist that improves fat oxidation and stamina on its own, while SR-9009 acts on Rev-erb receptors tied to metabolic rate and mitochondrial density. The two are frequently stacked together because their mechanisms complement rather than overlap, giving a stronger combined stamina and fat-burning effect.

Every box of iMuscle SR-9009 we sell carries a verification check-code so you can confirm it is authentic stock, not a copy. Orders dispatch from our UK warehouse the same day when paid before midday on a working day, going out via Royal Mail Tracked 24 in plain, unbranded packaging. Most customers across the UK have it in hand within one to two working days.

Yes, that is one of the reasons it is popular. During a cut it supports fat loss and helps preserve conditioning without adding water weight, while during a bulk it can improve work capacity so you get more out of harder training sessions. It does not build muscle mass on its own, so the results still depend on your training and diet around it.
