Equipoise 300 from Xeno Labs is an injectable steroid—specifically, Boldenone Undecylenate. Each milliliter packs 300mg, and the vial gives you 10ml to work with.
What’s in the vial?
It’s Boldenone Undecylenate (C30H44O3), which is basically a long-acting testosterone derivative. The undecylenate ester attached to it slows everything down, so the release is steady. It’s milder than testosterone (think 100:50 anabolic ratio), doesn’t aromatize much, and comes in grapeseed oil with a bit of benzyl alcohol. Once you inject, it sticks around—half-life is about two weeks, and you’ll feel it for up to a month.
Originally, this stuff was made for cattle to pack on muscle. In bodybuilding, though, it’s all about lean bulking, boosting your appetite, and improving endurance and vascularity. Most people run it for 12-16 weeks, usually with testosterone for solid gains, or stack it with Winstrol or Masteron when cutting.
Why bother with Equipoise?
You get steady, lean muscle—think 10 to 15 pounds per cycle. Your veins pop, your red blood cell count jumps (so, better endurance), and you won’t deal with much estrogen-related hassle. Appetite goes up, which is great if you’re trying to bulk. Plus, the slow release stops those wild hormone swings, and it works especially well with testosterone if you want clean gains without drowning in anti-estrogens.
But it’s not all sunshine. Some folks get anxious—bodybuilders call it EQ head. Your red blood cells can get too high (so, you might need to donate blood), and you can break out a bit. Appetite can spike hard. On the serious side, blood pressure might go up, cholesterol levels can shift, and long-term use can stress your heart. It takes a while to really kick in—expect 4-6 weeks—and sometimes the injection stings.
How do you use it?
Most guys shoot for 300 to 600mg per week—so, 1 to 2ml, either once or split into two shots, usually in the glutes or quads with a 23-25G, 1.5-inch needle. Beginners stick to 300-400mg; the more advanced crowd pushes up to 600-800mg. Cycles run long—anywhere from 12 to 20 weeks. Some use an aromatase inhibitor (like 0.5mg Arimidex every other day) if they need it. After the cycle, start your PCT two or three weeks later (Clomid and Nolva).
There are a bunch of ways to run EQ:
For lean bulking, try 400mg of EQ with 500mg of Test E for 12-16 weeks.
Cutting or recomp? Go for 300mg EQ, 400mg Test P, and 50mg Winstrol every day for 10 weeks.
Boost endurance with 300mg EQ alone plus 25mg Anavar daily (12 weeks).
Bridging between heavy cycles? Use 200-300mg per week.
Feeling ambitious? Stack 500mg EQ with 400mg Tren E and kick things off with 50mg Dbol for 14 weeks.
That’s the rundown—straightforward, no fluff.
