Bolasterol Mass Information (Prohormones)

Bolasterol Mass by

Manufactured by:
Pro Cycle Labs

For some reason, most of the write-ups I see in online stores insert the dosage infomation right in the middle of the compound nomenclature, making it hard to read.

Here's what you've got for anabolic compounds:

2a 17a Dimethyl 17a Hydroxy 5a Etiocholan 3-one 10mg (Superdrol)
2a,17a-dimethyl-5a androstan-17b-ol-3,3'-azine 15mg (Dimethazine)
13-ethyl-3-methoxy-gona-2,5(10)-dien-17-one 15mg (Max LMG/Tren)

Bolasterol also has some other 'active' stuff in it:

6,7-dihydroxybergamottin 25mg
Niacinimide 50mg
Pyroxidine Hcl 25mg
Piperine 95% 5mg
Cyanocobalamin 500mcg

And the typical other junk:
Gelatin, Rice Flour, Magnesium Stearate, Stearic Acid, and Silica

Bottle recommended dosage: 1 capsule in the AM and one capsule after a PM workout or prior to bed. Don't exceed more than 2 capsules in a 24 hour period.

What you've got here is a triple stack of Superdrol, D-Zine and Max LMG(Tren). They call this the Mass Stack mad that's no joke! Both Superdrol and Max LMG/Tren are well known for packing on pounds of muscle (provided your diet and exercise are on track). As for Dymethazine, results are mixed, but many users report impressive gains.

If you've read any of my other comments on pre-built stacks, you know I'm against them, primarily because I want to control the amount of each compound I'm taking individually and not rely on someone else to deliver what they think is the best dose.

Procycle Labs is recommending 2 caps a day, so let's break that down. At 2 caps, you're getting:

20mg Superdrol
30mg Dymethazine
30mg Max LMG/Tren

For a stack, the Super/D-Zine is probably pretty good. Depending on your experience, it might even be a bit underdosed. Most users will be fine at 20mg for Superdrolm and 30mg for D-Zein, but experienced users will probably want to bump up to 3 caps a day for a 30mg/45mg combo.

At 2 caps a day, you're going to get 30mg og Mac LMG/Tren, and that's too low. Even at 3 caps a day, you're dose will still be only 45mg. New users see good results at 60 - 90mg, while experienced users can head up into the 90 - 120mg range.

Now since this is a stack, you can probalby get away with everything being a little underdosed (i.e. 20mg Super and 30mg D-Zine is probably fine), but the Max LMG/Tren is just too low.

The last thing to consider is recommended cycle times. Max LMG/Tren returns best result in 5-6 week cycles. Superdrol can be harsh 0 you often see 3-4 week cycles here, with only hardcore users going longer. D-Zine is in the middle, with 4-5 weeks being a good lenght.

So you've got three compounds, each with different recommended cycle lengths. Hard to accomodate that with a single stack like this.

No joke about it, if you choose this, you'll probably see good results, but you won't see the best results possible if you were to use the optimal doses and cycle lengths.

These three compounds can be harsh, so make sure you've got your support supplements ready to go. Superdrol, especially, is know for shutdown, so have a strong PCT ready to go - no over-the-counter here!

13-ethyl-3-methoxy-gona-2,5(10)diene-17-one (Max LMG)

Trade names include Max LMG, Tren, Trena, AKA Methoxygonadiene

Common dosage: 60-120mg daily
Common cycle length: 4-6 weeks
Methylated: No
Half-Life:Long (48-72 hours)

Not a 17aa steroid so liver toxicity is not as harsh as with 17aa steorids, however the ethyl group on C-18 may make it slightly more toxic than a non-ethylated steroid (while increasing its oral bio-availability). Max LMG is progestin designed to give solid gains in muscle mass with low water retention. The progestational activity of methoxygonadiene (once it is converted to its active metabolites) is considered to be slightly stronger than nandrolone. This means muscle building with Max LMG in your cycle gives you higher quality hardening effects. Since it acts as anti-progesterone, there are decreased negative effects of extra estrogen and increased libido.

It is legal because it is a progestin, like trenbolone, nandrolone, methyltrienolone and Methyl-Dien. As a progestin, Max LMG is structurally related to the pill RU-486 and as such acts as an "anti-progesterone". This results in decreased estrogen-like effects and an increase in libido.

Research suggests that Max LMG has a half-life of about 6 hours, though it appears that it is closer to 10 hours based upon plasma levels maintained in test subjects. It is not a 17-alkylated analog and has a low potential for liver toxicity.

Most users report good results at a dosage of 75mg a day.

Some comments from users:

"As stated, appears to be an all out bulker. Great for size and strength, but notorious for bloat and the potential for gyno. I've also read that it kills libido pretty quickly. Some of the makers claimed that the libido would remain fine if one didn't use too large of daily doses though. I remember seeing people getting decent gains from 40mg - 50mg (depending on the product). It looks like most guys go up to 75mg though."

"Would be my favorite if it didn't make my nips start burning by the end of week two. Rapid weight gain on it plus the fact its not methyl are pluses. Just keep in mind i've seen many complain about it easily aggrevating gyno."

In the stomach acid, the C-3 methoxy group is rapidly cleaved off and the double bond on the A ring at C-2 is lost. At this point, a 3-oxo is formed and a metabolite known as 13b-ethyl-nor-androstenedione is created, which is chemically similar to norbolethone, and probably where this compound gets most of its effects.

13b-ethyl-nor-androstenedione is about equal to testosterone in anabolic potency, yet less androgenic. This would make this compound fairly light on the hairline with minimal chance of acne or other androgenic side-effects.

With low androgenic activity, this compound may negatively affect the libido and erectile function. The lack of androgenic potency and progestational effects make this compound likely to cause gyno symptoms. Users could stack this compound with testosterone or one of its non-aromatizing metabolites to preserve DHT levels and possibly prevent these side-effects.

Users experience rapid weight gain from this compound partly due to subcutaneous water retention from the progestational activity. Therefore the overall gains from this compound may lead to a bloated appearance. Because of the progestational effects, users should avoid stacking this compound with other gyno aggravating compounds. Max LMG can aromatize to estrogen in small amounts, however not to any significant degree, therefore an aromatase inhibitor would provide little protection against this compound's side-effects.

Max LMG immediately converts in the stomach into a 13b alkylated compound (13b ethyl nor androstenedione) and then makes it all the way to the liver because it is ethylated to survive first pass, and is converted into 13b ethyl nor testosterone, a steroid similar to norbolethone aka the clear.

2a,17a-dimethyl-17a-hydroxy,5a-etiocholan-3-one (Superdrol)

Seems to be yet another chemical nomenclature for Superdrol:

2a,17a-dimethyl-5a-androst-3-one-17b-ol (Superdrol)

Superdrol is a powerful anabolic designer steroid brought to market in 2005, however due pressure by the FDA, the original Superdrol was pulled and is no longer available. Like many other compounds, it has been made available again through the production of clones.


An alternate nomenclature for Dimethazine, the other one being D-Zine (17b-hydroxy-2a,17b-dimethyl-5a-androstan-3-one-azine).

Dymethazine (aka mebolazine) was brought to market by iForce Nutrition in 2009, however, despite Dymethazine being 'legal' it was largely taken off the market due to recent FDA activities. Despite this, clones of the original Dymethazine have already been brought to the market. Dymethazine and DZine are interchangeable.

Dymethazine is essentially two superdrol molecules attached by a nitrogen atom. Stomach acid breaks the two superdrol molecules apart. Dymethazine is also known as mebalozine. Dymethazine is very close to Superdrol, except it's two superdrol molecules attached to each other. Despite this, Superdrol remains the more powerful compound.

One advantage Dymethazine has over Superdrol is the lower likelihood/greater managability of side effects. Dymethazine is an incredibly potent compound and carries the same risks as any other powerful anabolic steroid or pro-hormone.

If you were to believe manufacture claims, then this is the end all, be all of prohormones/designer steroids: "A never before seen molecular structure enables Dymethazine to harness one of the strongest anabolic:androgenic ratios ever seen. Featuring a greater myotropic effect than Winstrol, Oxymethalone, Testosterone Prop, and Methyl-Test, Dymethazine has been shown to not only be the strongest PH ever made, but also one of the strongest compounds ever produced."

Despite this extravagent claim, user reviews seem to be mixed....

6,7-dihydroxybergamottin (DHB)

Along with the chemical Bergamottin, it is believed to be responsible for the grapefruit juice effect in which the consumption of the juice affects the metabolism of a variety of pharmaceutical drugs.

Chemically, bergamottin and 6,7-dihydroxybergamottin are linear furanocoumarins functionalized with side chains derived from geraniol. They are inhibitors of some isoforms of the cytochrome P450 enzyme, particularly CYP3A4. This prevents oxidative metabolism of certain drugs by the enzyme, resulting in an elevated concentration of drug in the bloodstream.

Normally, the grapefruit juice effect is considered to be a negative interaction, and patients are often warned not to consume grapefruit or its juice when taking medication. However, some current research is focused on the potential benefits of cytochrome P450 inhibition. Bergamottin, dihydroxybergamottin, or synthetic analogs may be developed as drugs that are targeted to increase the oral bioavailability of other drugs.


Cyanocobalamin is a common vitamer of the vitamin B12 family. A form of vitamin B12 called hydroxocobalamin is produced by bacteria, and then changed to cyanocobalamin in the process of being purified in activated charcoal columns after being separated from the bacterial cultures. Cyanocobalamin is the vitamin B12 that is found in most meat and meat products, and in most vitamin B12 supplements.

Cyanocobalamin usually does not even occur in nature, and is not one of the forms of the vitamin that are directly used in the body. However, animals and humans can convert cyanocobalamin to active (cofactor) forms of the vitamin.

Vitamin B12 is important for growth, cell reproduction, blood formation, and protein and tissue synthesis. Sources include organ meats, meat, fish, eggs, milk and cheese. Vitamin B12 is not found in vegetables. The liver is the main storage site of vitamin B12. The human body stores about 4mcg of Vitamin B12 (2 in the liver and 2 elsewhere). These stores are enough to last for one to three years.

RDA is very small, being just 1mcg daily for adults and as little as .2mcg for children.


Gelatin is a tasteless substance created from collagen found in animal skin and bones. It is used to thicken liquid in processed foods as well as having applications in photography, cosmetics, and pharmaceuticals. Gelatin is found in many forms of candy, marshmallows, Jell-O, and some types of yogurt. Gelatin can be bought in many grocery stores for use in home cooking. In the vast majority of cases, gelatin is not harmful to the consumer.

Magnesium Stearate

Magnesium stearate is often used as a diluent in the manufacture of medical tablets, capsules and powders. In this regard, the substance is also useful, because it has lubricating properties, preventing ingredients from sticking to manufacturing equipment during the compression of chemical powders into solid tablets.

Magnesium stearate is the most commonly used lubricant for tablets. Studies have shown that magnesium stearate may affect the release time of the active ingredients in tablets, but not that it reduces the over-all bioavailability of those ingredients.


Vitamin B3 is made up of niacin (nicotinic acid) and its amide, niacinamide, and can be found in yeast, meat, fish, milk, eggs, green vegetables, and cereal grains. Dietary tryptophan is also converted to niacin in the body. Vitamin B3 is often found in combination with other B vitamins including thiamine, riboflavin, pantothenic acid, pyridoxine, cyanocobalamin, and folic acid.

There's been specualtion that Niacinamide has positive effect on the HDL/choelsterol ratio, however, research indicates it is Niacine, not Niacinamide, that affects cholesterol levels.

Niacin decreases the rate of hepatic synthesis of very low-density lipoprotein (VLDL) and low-density lipoprotein (LDL) while raising high-density lipoprotein. This has led to a lowering of serum cholesterol by 10 to 15% and triglycerides by 20 to 30%. Niacinamide is not effective in lowering serum cholesterol.

High doses of Niacin can cause an uncomfortable flushing effect where the skin of the upper body reddens and become itchy due to histamine release. Tolerance after a few weeks of treatment usually develops and the flushin effect desreases.

Niacinamide is often sold in supplement form as no-flush Niacin, but it doesn't have the same positive lipid effects.


Piperine is the alkaloid responsible for the pungency of black pepper and long pepper, along with chavicine (an isomer of piperine). It has also been used in some forms of traditional medicine and as an insecticide.

Piperine has been found to inhibit human CYP3A4 and P-glycoprotein, enzymes important for the metabolism and transport of xenobiotics and metabolites. In animal studies, piperine also inhibited other enzymes important in drug metabolism. By inhibiting drug metabolism, piperine may increase the bioavailability of various compounds and alter the effectiveness of some medications.

Piperine may also have some harmful side effects. Preliminary evidence shows it may be toxic in some circumstances, and may even interfere with reproductive processes, including negative effects on sperm. Piperine at doses higher than 15 mg daily may affect the metabolism of a wide range of drugs. Even lower doses may affect the bodys metabolism of some drugs.

Piperine may also form cancer-causing substances when eaten with nitrates. Experts suggest that people who take piperine supplements should be careful when also eating food that contains nitrates as a preservative.

Not enough human studies have been done to determine the side effects of chronic supplementation with piperine. For the time being, it is a good idea to take 2 days off a week, and one full week off each month from the use of a piperine supplement. It is quite likely that the small amounts of piperine could provide health benefits while larger amounts could be toxic or damaging to the liver or other organs.

Pyroxidine Hydrochloride (HCL)

Pyridoxine hydrochloride, or pyridoxine HCL, is a form of vitamin B6 that can be taken as a supplement and is mainly used for treating vitamin B6 deficiency.

Vitamin B6 includes pyridoxine, pyridoxal and pyridoxamine, which are three closely related chemical compounds. The body metabolizes these substances in to pyridoxal phosphate, which acts as a coenzyme in biochemical reactions in the blood, central nervous system and skin. Vitamin B6 is also important for fat, carbohydrate and amino acid metabolism.

Rice Powder (Rice Flower)

Rice powder (rice flower) is a form of flour made from finely milled rice. It is distinct from rice starch, which is usually produced by steeping rice in lye.

Rice flour may be made from either white rice or brown rice. Rice flour is a particularly good substitute for wheat flour, which causes irritation in the digestive systems of those who are gluten-intolerant.

Silicon Dioxide (Silica)

The chemical compound silicon dioxide, also known as silica, is an oxide of silicon. Silica is most commonly found in nature as sand or quartz.

Silica is common additive in the production of foods, where it is used primarily as a flow agent in powdered foods, or to absorb water in hygroscopic applications. It is the primary component of diatomaceous earth which has many uses ranging from filtration to insect control. It is also the primary component of rice husk ash which is used, for example, in filtration and cement manufacturing.

Stearic Acid

Stearic acid is the saturated fatty acid with an 18 carbon chain and has the IUPAC name octadecanoic acid. It is a waxy solid, and the salts and esters of stearic acid are called stearates. It occurs in many animal and vegetable fats and oils, but it is more common in animal fat. The important exceptions are cocoa butter and shea butter, whose fatty acids consist of 2845% stearic acid.

Stearic acid is used in making candles, plastics, dietary supplements, oil pastels and cosmetics, softening rubber, and hardening soaps. Stearic acid is used in aerosol shaving cream products. It is used along with simple sugar or corn syrup as a hardener in candies and to form margarines, shortenings, spreads, and as a cream base for baked products.

Even though stearic acid is a saturated fat, studies have suggested that it has little effect on blood cholesterol levels, because such a high proportion is converted to oleic acid.
