Laurabolin is an alternate form of nandrolone. It's a good substitute if Deca Durabolin is not available and you absolutely must have nandrolone. The main difference here is the length of the ester. A laurate ester, as in laurabolin, has 12 carbons as opposed to the 10 carbon decanoate ester that Deca Durabolin has. That makes it slightly longer acting. But you would still want to use weekly injections for all intents and purposes, so its basically interchangeable with Deca. The only product truly of interest is Loeffler's Laudrol LA. While Loeffler is the least reputable company on the list, it's the only one that makes Laurabolin in a decent concentration. The 25 and 50 mg/ml versions are really not interesting as they require weekly, single-day injection of 8-16 ml. Not a pleasant or wishful experience in anyway. As with Deca in the same concentration, its rarely if ever used. That's why Deca, which comes in 100 and 200 mg/ml as well, has more popularity than Laurabolin and a more wide-spread availability.
One plus of Laurabolin, because its less popular, is the reduced chance of getting scammed. Most of the crooks who fake steroids will opt to fake Deca because its in higher demand. And since everyone knows Laurabolin is mostly 25 and 50 mg/ml, there wouldn't be an interest in it either. Same with Deca in low concentrations. Nonetheless, if you wanted to be sure of not buying a fake when shopping for Deca, I would tell you to go with the lower concentrations. Although of late I'm more inclined to tell you to forget about nandrolone altogether and opt for Boldenone instead. Not only because its equally available and you have less chance of getting scammed, but also because boldenone is safer estrogenically, has no progestagenic action, provides lean muscle growth, does not bloat you up, is not as suppressive of natural testosterone, is stronger mg for mg and overall a much better and safer steroid. Like I said, this is mostly a product for the old-school vets that absolutely must have nandrolone (old myths die hard).
Since the base compound is nandrolone, you can count on some serious bloating. Nandrolone's androgenic component is mild, but it has a progestagenic binding that allows it to worsen estrogenic effects. Water retention being one of them. Its also a potent aldosterone agonist, and one of the actions of this hormone is to store more sodium. Increased sodium storage means increased water retention. So bloating is something you can pretty much expect. The estrogenic/progestagenic component also makes it a verifiable risk for fat gain and Gyno (growth of breast tissue in men). Because of the progestagenic component, aromatase inhibitors like arimidex, cytadren and proviron are fairly useless at countering the side-effects.
Its estrogenic effects combined with the fact that nandrolone readily re-esterifies in the body makes it have some additional problems. First of all on the suppression of natural sex hormones. Natural testosterone is shut down during the use of anabolic steroids, and the idea is to get it to come back online as soon as possible after a cycle so you can maintain most of the mass you gained. Because nandrolone 'lingers' in the body for quite some time and is a tad estrogenic, it tends to suppress the natural endocrine system much longer. With Laurabolin, who's ester is even longer acting, this problem may be even more pronounced. Even with the use of HCG and Nolvadex or Clomid, problems of this nature can arise. That means extensive post-cycle recovery (7-10 weeks) periods and a high chance of losing a lot of the mass you gained. The second problem is the detection time. Nandrolone can be detected in the body 18 months after last use, and word has it the new batch of tests will be able to detect almost 2 years after last use. People subject to random drug testing for anabolic steroids will find any nandrolone particularly unsuited for that purpose alone. Someone should tell all these idiot pro athletes getting busted for nandrolone use lately. You would think people at that level would be more informed.
Of course its not all bad. Nandrolone owes its popularity to its mild androgenic nature. While being a decent enough androgen itself, it does not convert to a more androgenic specimen in androgen responsive tissue such as prostate, skin and scalp. On the contrary. As opposed to testosterone which can form the 3-4 times more potent androgen DHT in these tissues, nandrolone will form DHN, a compound that is several times LESS androgenic. That makes nandrolone one of the safest steroids androgenically speaking, and a very low risk for hair loss and prostate hypertrophy. But still, boldenone makes a nice substitution, because it can rival nandrolone in this aspect. It doesn't have any conversion at the 5AR enzyme whatsoever and keeps its initial potency in all tissues.
Like Deca Durabolin, Laurabolin too is mostly used as a base compound for bulking stacks. Because of its low androgenic nature it allows a user to increase his gains without having to risk more androgenic risk associated with stronger compounds. The best match for it would be a long acting testosterone like sustanon 250, enanthate or cypionate. Augmenting your dose of testosterone with a dose of Laurabolin that is roughly 80% of that dose. So if you would use 500 mg of testosterone, stack it with 400 mg of Laurabolin weekly. It also makes a good match in stacks with daily doses of Dianabol (methandrostenolone) or Anadrol (oxymetholone). The addition of either testosterone or Proviron (mesterolone) is highly recommended, because nandrolone seems to have an extreme suppressive effect on the libido. The term Deca dick is often used here, where temporary impotence or a severe loss of sexual interest can occur. Testosterone or Proviron can somewhat counter this problem.
In terms ancillaries, it may be wise to have an estrogen receptor antagonist like Nolvadex or Clomid handy when using a long acting nandrolone like Laurabolin. Aromatase inhibitors (cytadren, proviron, arimidex) have a limited use, because nandrolone can aggravate circulating estrogen by binding the progesterone receptor, so its smarter to keep estrogens from binding by using a receptor competitor like the aforementioned. Because nandrolone is also nasty suppressive stuff, the use of HCG and Nolvadex or Clomid is an absolute must. To be absolutely sure nandrolone won't cause any problems in this area, I would actually suggest you discontinue your Laurabolin 1-2 weeks prior to ending your stack/cycle. That will give it a chance to somewhat clear the body by then.
