1-Androsterone (1-Testosterone) Prohormone Profile

The 1-Andro (1-DHEA) Prohormone Profile

Presentation of the 1-Androsterone (1-Testosterone) prohormone

1-Androsterone (1-Testosterone) prohormones are very similar to the original 1-AD prohormone back in the 2000’s. Redefine Nutrition and AMS are pretty much the two manufacturers that launched the market of the 1-Androsterone (1-Testosterone) market.

Main ingredient of 1-Andro prohormone is 1-androstene-3b-ol-17-one (1-androsterone or 1-DHEA if you prefer). After ingesting it, your body converts it to the potent androgen 1-Testosterone.

Due to similar results – gains with a legal status, 1-Andro prohormones can be used as an alternative to Bold (1,4 AD bold 200 – Boldenone) prohormones.

Additional informations on a cycle of 1-Androsterone prohormone

Legal and non methylated, 1-Androsterone (1-Testosterone) are one of the safest and mildest prohormone on the market. This prohormone is very good for beginners doing their first cycle. Since it’s non methylated, 1-Andro prohormones can be stack with an other prohormone (methylated or not) to do a prohormone stack.

Results and gains are the in “mild moderate” range. Don’t get me wrong, you will get some lean muscle mass gains but don’t expect it to be like Superdrol. Gains up to 10 solid lbs of muscle can be reached with a 6 weeks cycle. Depending on your diet, you can also have some fat loss.

Regarding the side effects, you can expect low stuff. Since it’s convert to 1-testosterone which is a DHT derivative, some people can have som hair shedding at high dosages.

1-Androsterone (1-Testosterone) prohormones are not methylated so there is no toxicity for your liver. No liver or full cycle support supplements needed but this is still highly recommended as any prohormone can put stress on your body.  For the post cycle therapy, you can do an OTC PCT if you take it alone but the best is to go with normal PCT with SERM.

    can I stack this with Adrenosterone (11-Ketotestosterone) for my first cycle looking to recomp cutting..

      Of course ! Both will help build lean muscle mass and drop some bodyfat level. Strength and agression will be increased too which is very nice.

    what’s the difference with 3b-enanthoxyandrost-1-en-17-one (Super-1-DHEA) ? (dosage, effect, side effect, results)

    manufacturer says his Super1DHEA doesn’t Convert to DHT, is that because it’s already a DHT derivative?

    Btw Thanks for the info on your site.

      Hello, I don’t know much about 3b-enanthoxyandrost-1-en-17-one AKA “Super 1 DHEA” but here is what I found about it.

      Basically, it’s a modified DHEA (ester form) compound with a two step conversion from testosterone. Manufacturers claims a lot from it (better bioavailibity, etc.) but it’s about the same as a regular 1-andro prohormone except it has an higher price. Dosage is about the same as the other 1-Andro prohormone, effects and results “should” be better with less sides. This compound (3b-enanthoxyandrost-1-en-17-one) had a lot of hype because it was in Andro Mass.

      There are some good reviews but also bad reviews. If you can have it cheap, go with it but if not, go with a standard 1-Andro prohormone. This is the best I can recommend to you.

      If you decide to go with it, you can post here your review here.

      I would be glad to hear more about it !

    Advanced Muscle Science 1-Androsterone RDe
    Advanced Muscle Science Ultra Concentrated Arom-X RDe and a multi vitamin

    and what doseage cycle do I follow the 1 on the bottle or like it says on here can u help me out ? Email me if u can

    • admin December 11, 2013 at 7:12 am - Reply

      Hey Jaysin,
      Everything you have is good. For the post cycle therapy, I would use Arom-X (if you already bought it) and Erase from PES (a powerful anti estrogen legal supplement). If you don’t already have Arom-X on hand, skip it and just go with Erase PES.
      For the dosage, all depend the results you expect : mainly fat loss or muscle growth ?
      300 mg daily (3 serving size of 100 mg) is the minimum to feel somewhat fat loss. 600 mg daily is the “sweet spot” for both fat loss and muscle growth if it’s your first cycle of prohormone.

        Hey Kem,
        1-Andro is a non methylated prohormone so there is not obligatory to “pre-load” before the cycle. But a pro-load is always good for all kind of prohormones. The choice is up to you.
        If you have enough cycle support supplements, I suggest you to do it.

    I want to take a 1-Andro supplement, really like what I’m seeing about Finaflex, but my question is..
    Is it really necessary to take a SERM for such a light pro hormone? I’ve seen so many guys say you to HAVE to have a serm for any type of pro hormone. I’d rather not have to bother with a research chemicals and was wondering what OTC PCT in your opinion, if any, will guarantee complete protection from gyno?

    • admin March 29, 2014 at 11:10 pm - Reply

      For 1-Andro, you can do what we call an OTC PCT under some conditions : do not stack it with an other prohormone and don’t take high dosages . If you are going to do that, we recommend to go with a SERM.

      Let’s make it clear : we (and many other people) always recommend first to take a SERM for a post cycle therapy because that is the best thing (beside powerful aromatase inhibitors like letrozole, anastrozole…) to protect you against “bitch tits” (gyno) and many other bad effects from estrogen.

      OTC PCT Supplements are not enough powerful to give you the same protection same if some are pretty good (AD-3 Lecheek Nutrition for example). Of course, some people have run harsh prohormones like superdrol in the past without doing a proper pct and they did have any problems but that is not common.

      If you decide to go for an OTC PCT, here is two suggestions of good anti estrogen supplements you can buy “over-the-counter” : AD-3 Lecheek Nutrition, Erase Performance Enhancing Science (PES). Both contain the same main ingredient and they are pretty powerful and available pretty much everywhere.

    Is arom-x considered a SERM? I was planning on running that along with tribulus for a pct.
    Also would hawthorn and milk thistle be enough of support?
    I was just going to run ams 1-andro as labeled

    • admin July 28, 2014 at 1:41 pm - Reply

      Hey Kool8bro,
      Arom-X is not a SERM, this is an OTC PCT supplement (not the best).
      For your post cycle therapy, I suggest to you to use AD-3 PCT from Lecheek Nutrition (pretty much the best OTC PCT on the market) : Link to AD-3 PCT Info Page
      Hawthorn and Milk Thistle is okay for cycle support since 1-Andro is non methylated.

    What is this likelyhood of permanent damage to the testicles after using 1-andro?
    I would like to use this PH every once in a while (maybe one cycle every 1 – 2 years) to break through a plateau.
    But if I’m going to irreversibly damage my own testosterone production by doing one cycle.. Ill probably skip this 🙂

    • admin August 16, 2014 at 11:06 am - Reply

      Hey Rob,
      In my opinion : If you do correctly (with proper protection) a prohormone cycle, you have pretty much zero risks of permanent damage to testicles. Yes you will lower your own testosterone production during and short after the cycle but with products like a SERM you can recover quickly.
      Of course, it’s impossible to tell you exactly that you have 0% of risks because everyone can act differently to external hormones.

    So no liver support is needed ?

    • admin September 16, 2014 at 2:50 pm - Reply

      Hey Nick,
      Any prohormone (methylated or not) will put stress on your liver. The safest recommendation I can give is to take a liver support supplement.
      If you’re low on budget, save a bit and wait or simply don’t take one.

    Hello, I am looking into taking a mild prohormone with the least side effects, but would like to put on some size. Was considering either decavol liquid or 1-andro liquid. Which would you recommend, and I don’t understand the conversion from tablet to liquid in the dosing. Please help me understand.
    Thanks John

    Hi, I’m 37 years old and am looking into either 1-andro or decavol for some lean gains. Which would you suggest. I am looking for something with the least side effects. Also how does the dosing change if I get it in liquid version? I was suggested to get the liquid versions from someone. Any help would be appreciated.
    Thanks John

    • admin September 21, 2014 at 4:02 pm - Reply

      Hi John,
      Here is my opinion : 1-Andro is a more effective prohormone than Decavol. Both prohormones have in general a very low level of side effects.
      1-Andro has the possibility to give lean gains and cut fat a little bit at the same time while Decavol is more geared toward cutting goals. It depends a lot about your diet and training too.
      Now for the dosing (tablets vs liquid), there is no difference for 1-Andro. You have to take the necessary number of tablets or ml drops to get the XX mg you want daily.
      I can’t tell you much about the dosing of Decavol because I’m not really experienced on this specific prohormone.
      One more thing, I’m not really into the liquid vs tablets debate some guys have. Of course, it might have a slight impact on the absorption but I don’t think there is a big difference.

    Thank you for your reply. Now I have a new question, of the two 1-andro products between finaflex and ams which would you suggest? Also dosing and otc and pct information would be very appreciated.
    Thanks again, John

    • admin September 30, 2014 at 4:28 pm - Reply

      I would go with Finaflex. Both are the same product with a very little difference in the formula.Depending where you get it, you will only find a difference in your wallet.
      Considering it might be your first cycle (?), I would go with this doses (cycle of finaflex 1-Andro) :
      – Week1 : One pill 3 times a day
      – Week2 : One pill 3 times a day
      – Week3 : One pill 4 times a day
      – Week4 : One pill 4 times a day
      – Week5 : One pill 4 times a day
      – Week6 : One pill 4 times a day
      – Week7 : One pill 2 times a day of Revolution PCT Black by Finaflex (OTC PCT)
      – Week8 : One pill 2 times a day of Revolution PCT Black by Finaflex (OTC PCT)
      – Week9 : One pill 1 times a day of Revolution PCT Black by Finaflex (OTC PCT)
      – Week10 : One pill 1 times a day of Revolution PCT Black by Finaflex (OTC PCT)
      You will need 2 bottles of 1-Andro + 1 bottle of Revolution PCT Black. Keep the remaining pills for later or just garbage if you don’t plan using them.

    Hey guys, just a quick update. About 3 days left on 1-andro ams. I did the recommended dosage at 1 ml twice a day for 4 weeks. I put on about 3 pounds which is not a lot but I thickened up quite a bit all around especially my arms. I definitely loved it and will probably do it again around spring at 3 ml a day for probably 5 or 6 weeks. Just not sure if pct could remain the same or if a serm would be needed. Anyway thanks for the advice again.

    Hey man I was thinking about stacking this with anabolic technologies xtreme mass since I’m familiar with the XM from past usage (the only PH I’ve ever taken before for 2 different cycles). Do you think this would be a good mix? If not what would be a better alternative? Finally how would you go about stacking these such as the order goes?

    I am thinking about running a cycle of Finaflex 1 Andro. This is my very first cycle of anything, so I want to play it safely as possible. So with that being said, is there anything I could take during the cycle to support natural test levels/production? There’s a deal on Amazon that has Finaflex PCT BLACK as well as PURE TEST. If I took PURE TEST during the cycle, (followed by the pct), would that help support natural test levels/production? Or should I just take them both as a Pct?

    Hi, I was experimenting with Andro 1 and Andro 4. After doing more research, getting into the higher doses a SERM is recommended. I started taking about 200mg each and a bit scared of running Andro 4 high, so I planned on cutting off. I was able to order liquid Clomid and Novla for down the road when I want to bump it up more on the next cycle. What would be safe to do right now to stack these two? (Dosage for each) at what point should I consider taking a SERM? For the next cycle, assuming it’s going to be more, what would be an ample dosage for each in a stack? Thanks in advance!!!

Got myself 2 bottles of cycle assist for on and pct. On top of that i have pharmaceutical grade nolvadex and clomid for pct. And im getting some DAA for pct as well.

    Week 1 to 5
    100 mg of 1 andro (3rd week i’ll up the dose to 2 caps a day)
    4 caps of cycle assist 2 in the morning 2 in the evening

    First prohormone cycle. I’m following the labels recommendations for the 1 and 4 glory stack by sparta nutrition. Which is 1 andro and 4 andro . 115 mg each a day so 1 pill twice a day. Am I going to even see results with this dosage. I have reading after I started that beginners should take like 300 mg a day.

    • admin June 24, 2017 at 2:06 pm - Reply

      Hi Andy,
      Since it’s your first cycle, I would start with the recommended dosage for both products. After 1 week, I recommend you to increase the dosage to 3 caps daily for both products. Andro prohormones are good but you need high dosages to achieve great results.
