Oddly enough, I wasn't able to locate an bottle recommended dosage. I also have some question about the Methyl Clostebol as label listed.
According to henryv P-Mag and Methyl-Clostediol are the same:
from the post:
You can clearly see that they're written different, but henryv refers to it as "methyl clostebol" in his profile writeup.
When I specifically researched 4-chloro-17a-methyl-androst-4-ene-3b,17b-diol, the community regarded it as P-Mag/Promagnon as well.
I won't speculate as to dosage recommendations here, as the online stores selling this didn't list one. Still, for general knowledge:
Xtreme Stack Ingredients
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
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.
4-chloro-17a-methyl-androst-4-ene-3b,17b-diol (Promagnon)Also sold as Promag, P-Mag
Common Dosage: 50 - 100mg daily
Common Cycle Length: 4-6 Weeks.
Half-Life: 12 hours
Another methylated prohormone, this one is often compared to halodrol, though there is an important structural difference. P-mag lacks the C1-2 double bond common to boldenone derivatives like h-drol, boldione, dbol and M1,4ADD, having only a C4-5 (delta-4) double bond which makes it a closer structural relative of testosterone and methyl testosterone.
The difference becomes apparent when we look at what each one becomes in vivo: where some h-drol is metabolised via 3b-HSD to oral turinabol, p-mag becomes methylated clostebol. A 4-chloro group is common to both drugs, which will make both poor substrates for the aromatase cytochrome P-450 enzyme.
Clostebol is a synthetic anabolic androgenic steroid. Clostebol is the 4-chloro derivative of the natural hormone testosterone. It is a weak anabolic steroid used often by Germans during their Olympic glory days.
Promagnon users report size gains, with a lack of additional weight added in the last couple of weeks. Libido tends to remain positive, likely due to the more androgenic qualities of the drug.
The aforementioned positive attributes and the possibility of short cycle durations would make this an excellent choice for a first cycle, though as with any methyl it is a good idea to educate yourself about the possibilities of hepatic impairment
Promag is a versatile compound that will produce lean muscular gains and is suitable for cutting or bulking, however is typically most used when bulking Promag remains a popular due to minimal side effects and consistent dry gains that are relatively easy to maintain post cycle.
