Product overview

British Dragon Decabol & Durabol - Nandrolone Esters

British Dragon Decabol & Durabol is nandrolone in two esters, sold as separate vials rather than one blend. Decabol 250 carries nandrolone decanoate, the slow ester that holds a level for a week or more, and Durabol 100 carries nandrolone phenylpropionate, the short ester that starts and clears quickly. Nandrolone is a 19-nor androgen, one carbon removed from testosterone, so it builds mass with less water than the testosterone esters but brings its own effects.

Two formulations - Decabol 250 (decanoate) and Durabol 100 (phenylpropionate)
10 ml multi-dose vials, oil-based intramuscular injection
GMP-manufactured and HPLC-verified - COA on file per batch
International listing with a U.S. domestic option where stocked

Variant Comparison

The two vials carry the same hormone, and the ester decides how quickly it arrives and leaves.

Variant	Concentration	Half-Life	Injection Frequency	Typical Use
Decabol 250 (decanoate)	250 mg/ml	6 to 12 days	Once or twice weekly	Long mass phase
Durabol 100 (phenylpropionate)	100 mg/ml	Active life 2 to 3 days	Every other day	Short block, faster exit

Decanoate is the classic long nandrolone ester: fewer injections, a steadier level and a slow tail. Phenylpropionate does the opposite, suiting a shorter block, a faster exit before recovery, or a first look at the compound. The same ester split appears on other nandrolone products on the shelf, including the Deca 200 Test E 200 blend and Nandroxyl.

How Nandrolone Works

Nandrolone binds the androgen receptor like testosterone but aromatises far less, reported at around a fifth of testosterone or lower, so water retention and estradiol problems are milder. It also carries progestogenic activity, which is the source of the side effects that are specific to this compound: raised prolactin, and libido or erectile problems that can appear even when estradiol looks normal. Nandrolone suppresses the body's own testosterone production strongly, so a testosterone base and a clear recovery plan are part of any sensible arrangement, and an aromatase inhibitor such as Arimidex is used only when blood work shows high estradiol.

Dosage & Administration

No approved dose exists for this line, so the figures below are community protocols. Reported weekly totals for nandrolone run from roughly 200 mg at entry to 600 mg, split into two shots for decanoate and every other day for phenylpropionate. Because the 19-nor backbone shuts down natural production, recovery is Nolvadex 20 mg daily for four weeks, with Clomid as the alternative, started only after the decanoate has cleared. Metabolites stay detectable for many months, which rules nandrolone out for anyone tested.

Quality & Authenticity

Each batch is produced under GMP conditions and verified by third-party HPLC, with a Certificate of Analysis held for the batch. Store the vials upright at room temperature, away from light, excess heat and moisture, and do not refrigerate or freeze them. Decabol and Durabol are laboratory products, not licensed medicines in the United States or the European Union.

Stacks

Decabol With A Testosterone Base

Decabol 250 twice weekly beside Testabol 250 mg of cypionate or enanthate as the base, over ten to twelve weeks. Without a base the suppression of the 19-nor shows up as low energy and libido.

Expected outcome: steady mass gain with the natural axis held in check.

Short Durabol Block

Durabol 100 every other day for an eight-week block, with the short ester chosen so the compound clears within days of the last shot instead of weeks.

Expected outcome: a shorter exposure window before recovery starts.

Recovery After Nandrolone

Nandrolone suppresses natural testosterone, so the block closes with Nolvadex 20 mg daily for four weeks or Clomid, once the decanoate has cleared. A run with nandrolone products requires PCT.

Expected outcome: endogenous production restarts over four weeks.

FAQ

Before you ask

Questions, answered

It is nandrolone in two ester forms sold as separate vials. Decabol 250 is nandrolone decanoate at 250 mg per ml, the long-acting version, and Durabol 100 is nandrolone phenylpropionate at 100 mg per ml, the short-acting version. Both are 10 ml multi-dose vials, and the hormone is identical in each; only the ester, and therefore the release speed, differs.

The long ester is the usual pick for a mass phase, because decanoate stays in the blood for roughly six to twelve days and holds a level on one or two shots a week. Phenylpropionate has an active life of about two to three days, so it is injected every other day and suits a shorter block or a quicker exit. Neither is better in the abstract; the choice is about how long the exposure is meant to last.

Decabol 250 once or twice a week, Durabol 100 every other day, always intramuscular with the sites rotated. The short ester is the one that punishes a missed shot, since the level falls away within days. No regulator has approved a schedule for either product, so the frequencies describe how the esters behave rather than a prescription, and the weekly total is the figure that matters most.

Nandrolone aromatises far less than testosterone, so water retention is milder, but it carries progestogenic activity that can raise prolactin. That shows up as libido and erectile problems, sometimes with normal estradiol, and gynecomastia is possible without high estrogen. Natural testosterone production is strongly suppressed, and the class carries an FDA warning about serious liver and cardiovascular effects. Metabolites remain detectable in urine for many months.

Yes. Nandrolone suppresses the body's own testosterone, so the run is followed by tamoxifen 20 mg daily for four weeks, or clomiphene as the alternative. Timing depends on the ester: decanoate needs weeks to clear, so the SERM starts later than it would after a short ester such as phenylpropionate. Blood work six weeks afterwards confirms luteinising hormone, follicle-stimulating hormone and total testosterone.
