Nandrolone Esters - British Dragon

Buy Decabol 250 and Durabol 100 by British Dragon at XSteroids. These are the two nandrolone esters in the British Dragon line: Decabol 250, the long decanoate, and Durabol 100, the short phenylpropionate the boards call NPP. Same hormone in both vials - the only thing that changes is the clock.

Nandrolone is a prescription medicine in some countries; here it is a research product and the notes below are educational.

What Nandrolone Esters Give You

Nandrolone is a 19-nor compound: strongly anabolic, only weakly androgenic, and it carries one of the highest anabolic-to-androgenic ratios in the class. The draw in practice is size that arrives with joint comfort rather than raw aggression, and a softer side profile than most injectables of the same strength. What it is not is a fast compound - both esters release slowly and both shut down natural production hard.

The ester sets only the speed. Esterases cut the chain off the hormone, and the oil at the injection site acts as a depot that releases it over days. Longer chain, slower release; that single fact decides everything else on this page.

Decabol 250 - Nandrolone Decanoate

What it does and when you feel it

Decabol 250 is nandrolone decanoate at 250 mg/mL. The ester itself is hydrolysed within an hour, but the depot keeps feeding the blood for days: elimination half-life is roughly 6 to 12 days and the brand lists active life at 14 to 16 days. That is why one or two injections a week hold steady levels, and why the compound keeps working and keeps suppressing long after the last shot.

Expect a slow build. Levels take weeks to peak, and the joint relief people buy nandrolone for usually shows around week 4 to 6.

What a vial gives you

10 mL at 250 mg/mL is 2500 mg. At 300 mg a week that is about eight weeks of compound; at 400 mg a week six; at 600 mg four. A 400 mg week is 1.6 mL of oil, taken as one shot or split into two of 0.8 mL.

Durabol 100 - Nandrolone Phenylpropionate

What it does and when you feel it

Durabol 100 is the same hormone on a much shorter chain at 100 mg/mL. Sources do not agree on the exact number - the brand gives an active life of 2 to 3 days while third-party references put the half-life nearer 4.5 days - so the honest reading is that it clears in days, not weeks, and needs injections every other day at minimum.

That speed is the whole point. Frequent small shots keep levels flatter, water sits lower and the look is drier and harder than on the decanoate. Joint relief is reported within 7 to 14 days instead of weeks, and if side effects appear you are not waiting a fortnight for the compound to leave.

What a vial gives you

10 mL at 100 mg/mL is 1000 mg. At 300 mg a week a vial lasts about three weeks; at 400 mg two and a half; at 600 mg under two. 100 mg every other day works out near 350 mg a week, so one vial covers roughly three weeks. 0.5 mL is 50 mg and 1 mL is 100 mg.

Dosing in Practice

Decabol 250

The brand's range is 300 to 600 mg a week, split into one or two injections. Because the ester is so long, a missed day costs nothing, but so does a rising dose - the compound accumulates, so stacked weeks add up.

Durabol 100

The same 300 to 600 mg a week, but delivered every other day or daily. For reference, the approved medical dose of nandrolone decanoate in kidney-disease anaemia is 100 to 200 mg a week for men and 50 to 100 mg for women - well below athletic practice, and not a self-use protocol.

Estrogen, Prolactin and the Test Base

Nandrolone aromatises at roughly 20 percent of testosterone's rate, so estrogen is rarely the lead problem. The catch is progestagenic activity: combined with even moderate estradiol it is the route to raised prolactin, gynecomastia with normal estrogen numbers, and the flat libido and erectile problems that follow. The brand's own protocol keeps estradiol controlled with an aromatase inhibitor such as Anastrozole or Letrobol, and adds a dopamine agonist where prolactin stays high.

Suppression is the other certainty: solo use switches off natural testosterone production, which is why a testosterone base such as Testabol is standard alongside either ester.

Stacking Nandrolone

A long base plus Decabol 250 is the classic size cycle, with Methanabol as an oral kickstart while the depot builds. For a leaner run, Durabol 100 pairs with Boldabol, and Mesterolone is sometimes added when libido and drive need support - it does not add aromatisation.

PCT After Nandrolone

Recovery timing follows the ester, not the calendar. After Durabol 100 the brand suggests starting four to five days after the last injection. After Decabol 250 the wait is far longer - roughly three to four weeks - because the depot is still active and still suppressing; starting early means the SERM fights a compound that has not cleared. Either way the tools are a SERM such as Clomiphene or Tamoxifen for four to six weeks, with blood work to confirm the axis restarted.

Side Effects

Androgenic effects are the usual set: acne, oily skin, body hair, accelerated scalp hair loss, and in women voice change that can be permanent. Cardiovascular risk shows up as falling HDL and rising LDL, with lipids reverting after discontinuation. The label also carries boxed warnings for peliosis hepatis and liver tumours, and lists blood-pressure rise, fluid retention and pituitary suppression. Nandrolone is not a compound to run without monitoring.

Detection Time

This is the practical limit of the decanoate: the brand puts detection at 12 to 18 months, which rules Decabol out entirely for tested athletes. There is no taper or washout that makes a 2500 mg depot disappear quickly.

Storage

Keep the vials at room temperature, away from direct light, and out of reach of children. Do not use a vial with visible particles or discolouration; swirl rather than shake before drawing.
