Also known as
MK-2866
MK-2866 is a non-selective beta-agonist that acts on both the brown fat thermogenic pathway and the skeletal muscle anabolic pathways. The two products sold under this alias at SynthesisGear are the 60-tab 10 mg Ostarine tablets (Magnus) and the Magnus Fat Burn Course. Both are available in EU-only markets. Buyers should check the specific product, dose, and cycle length that matches their goals before ordering.
What It Is and How It Works
MK-2866 is a beta-adrenergic agonist. It increases basal metabolic rate by stimulating the brown adipose tissue thermogenic pathway, which drives heat production. At the same time, it activates skeletal muscle protein synthesis, supporting lean mass and fat-free mass retention. This dual action is why users often use it during cutting phases or alongside other agents to manage body composition while preserving strength.
Products Available Under This Alias

Users should confirm the exact dose, cycle length, and stacking protocol before starting a new regimen.
Questions & answers
How is MK-2866 different from other fat burners?
<b>Non-selective beta-agonist</b>. It acts on both the brown fat thermogenic pathway and skeletal muscle anabolic pathways. This dual action distinguishes it from many other weight-loss agents that primarily target appetite or lipolysis.
Who should not use it?
<b>Under 21, pregnant, lactating</b>. Also those with uncontrolled hypertension, severe asthma, or known hypersensitivity. Users on other stimulant agents should consult a doctor before combining.
Does it affect testosterone levels?
<b>No direct androgenic effect</b>. It does not bind to the androgen receptor. However, users with baseline low testosterone may notice secondary changes, so monitoring is advised if symptoms appear.
