I had given my opinion on Antaeus Labs in a prior post on Trenazone. Again, they seem to be a solid, honest, and educated company. There recent articles and actions have reinforced that. They have released some very well written and informative articles, which I found impressive (not that anyone could or should give a shit about what I think).
Antaeus Labs has released ULTRADROL the "latest greatest" PH on the market. ULTRADROL contains 2mg/capsule of Methylstenbolone AKA 2a,17a-dimethyl-17b-hydroxy-5a-androstan-1-ene-3-one ( pic below).
Methyl-stenbolone is not a new steroid; Stenbolone was released to the market in 1963 by Syntex as an alternative to their more toxic and androgenic Anadrol. Stenbolone has remained a steroid commonly used by bodybuilders.
Methyl-stenbolone is just a 17a-alkylated version of stenbolone. This compound or concept of this compound is not new comer to the "prohormone" market. It was originally a claimed ingredient in IDS Mass Tabs. However, chatter on the forum has said that lab test by FDA and others displayed it to be a low dose of Methylmasteron or SD. The company Culver Concepts produced a product called M-Sten 10 which was 30, 10mg, tablets containing what was claimed to be Methylstenbolone. There is not too much information on Culver Concepts M-Sten 10 but as far as I know it is legit methylstenbolone. Although Antaeus Labs does claim to be the first company with legit Methylstenbolone. Antaeus has stated they could only acquire 90% purity with this compound. The act of actually disclosing this actually adds to my respect for this company. I believe the 10% contamination is methasteron, which is completely fine with me. This just means that for each capsule there is 1.8 mg's of methylsten and .2mgs of methasteron.
I do not believe there is much real world experience with this compound. We will have to wait for ULTRADROL logs to come out. From a quick glance Methylstenbolone is some where between Methasteron and Methyl-1-testosterone. M1T with a 2-methyl added or Methasteron with a 1-ene added; this is depicted visually below.
You can expect this to be a fairly harsh compound, this is based solely off the fact that M1T was the harshest compound ever produced and SD is probably right behind it. Aside from the negative sides I am sure this will produce some solid gains. However, research shows that it may not be significantly different from M1T. Research shows that there is a decreased androgenic property, increase in AR selectivity, and increased anabolic properties with the addition of a 1-ene bond; for the 2-methyl addition there is an increase in anabolic activity which may be due to the prevention of aromatization. This info would lead you to believe that the combination of both the 2-methyl and 1-ene would create the ultimate anabolic! Butttttt according to Counsell RE, Klimstra PD, Colton FB. Anabolic agents. Derivatives of 5_-androst-1-ene. J Org Chem 1962;27:248–53 adding a 2-methyl to a 5a-androst-1-ene steroid did not show a dramatic effect on anabolic and androgenic potentcies. Keeping that in mind, do not write this off the 2-ene may actually effect the steroid in other metabolic ways. This compound could prove to be a great alternative to the old M1T, touted as one of the most popular legal anabolics of all time. To compare the anabolic/androgenic ratio of Methylsten to Methasteron: According to Vida Methylsten is 90-170:660 and Methasteron is 20:400. Remember that these are only ratios, not relative strengths of the compound. That is about as much as I can contribute without writing a book on the subject; for now we will have to subject ULTRADROL to the test of time.
