EQ 300 by Zyvex Pharmaceuticals
What Is EQ 300?
EQ 300 from Zyvex Pharmaceuticals is boldenone undecylenate at 300 mg per ml in a 10 ml vial. Boldenone is a slow, steady anabolic known for lean, quality mass gains that build up over a long run rather than a fast bloat.
Bodybuilders use EQ between testosterone and the harsher compounds: it adds appetite, endurance and dense muscle while staying mild on estrogen. The trade-off is patience - boldenone needs 10-12 weeks to show its real effect, and the long undecylenate ester has an unusually long detection time.
EQ 300 Dosage
Boldenone undecylenate is a very long ester; one or two injections per week hold stable levels.
| Protocol | Weekly Dose | Schedule |
|---|---|---|
| Lean bulk, first use | 300-400 mg | 1-2 injections |
| Standard run | 400-600 mg | 2 injections Common |
| Advanced | 600-900 mg | 2-3 injections weekly |
Runs last 12-16 weeks to see the full effect. One 10 ml vial at 300 mg/ml holds 3000 mg - plan the phase before buying.

EQ 300 Side Effects
EQ is mild on sides for most users, which is exactly why it is popular - and why it is sometimes overdosed.
- Estrogen - EQ aromatizes lightly, but it is not zero.
- Cardio markers - hematocrit can climb with long runs.
- Detection - the ester clears slowly; plan around testing windows.

What is Equipoise?
Equipoise is the trade name for boldenone undecylenate, a slow lean-mass anabolic. Zyvex Pharmaceuticals supplies it as EQ 300 at 300 mg/ml in a 10 ml vial.
What does Equipoise do?
Boldenone adds slow, dry quality mass with a strong appetite boost. It is used in long lean-bulking phases on a testosterone base.
How long does EQ take to kick in?
Boldenone is one of the slowest compounds: expect real changes from weeks 8-12 of a run. Patience is mandatory with EQ.
How long does boldenone stay in your system?
The undecylenate ester is very long: boldenone stays detectable for 4-5 months with sports testing. Plan around it.
What is the right Equipoise dosage?
Standard runs use 400-600 mg per week in one or two injections. A 10 ml vial at 300 mg/ml holds 3000 mg.
Does EQ increase appetite?
Yes, the appetite increase is the classic EQ effect, which suits bulking but can fight cutting diets.
What are the side effects of Equipoise?
Boldenone is mild: low aromatization, but hematocrit can climb on long runs and appetite swings are common.
Does EQ aromatize?
Very little. Boldenone has about half the estrogen conversion of testosterone, so AI needs are usually light.
Do you need a PCT after EQ?
Yes. EQ suppresses natural testosterone, and PCT starts later because the ester clears slowly.
