Prohormone Innovation by Celtic Labs

Believe it or not prohormone innovation is perhaps more active than ever before.  At the same time several of the first generation prohormones (1-androstenediol), and designer steroids (superdrol) are now banned.  But as always, the performance enhancing drug game always stays ahead of the regulating bodies.  In today’s prohormone world there is perhaps no other company being as innovative as Celtic Labs (Iron Legion, and LGI are a couple of others).  This post is long overdue, and because of Celtic Labs rapidly growing line of prohormones needs to be frequently updated.  Nonetheless here’s a look at what Celtic Labs is currently offering, and how to best use them.

The Regulars

Celtic DMZ – This is a standard dymethazine product (17b-hydroxy-2a, 17b-dimethyl-5a-androstan-3-one-azine).  Celtic DMZ comes in a 90 capsule bottle with 15 mg’s per capsule.  Dymethazine is two superdrol molecules bonded together.  Doses range from 15 mg to 45 mg’s per day depending on experience.  This means a 90 capsule bottle can last a full 30 days at 45 mg’s per day.  This is a strong no-nonsense compound great for bulking or cutting, but for some can come with side effects similar to superdrol.  Cycles of 3 to 4 weeks are recommended.

celtic labs prohormonesCeltic One – Celtic One (17a-methyl-1-androstenediol) is a clone of the popular CEL Alpha One (which was a clone of a former Legal Gear product long ago).  They are all precursors to methyl-1-testosterone (M1T), which was one of the more potent and harsh designer steroids of all time.  It is without a doubt one of the more potent mass builders on the market.  It is also hard on the liver, so keep the cycles to 3-4 weeks and eat like your life depends on it.

Celtic Sten – This is a new one by Celtic Labs created simply for the demand.  Celtic Sten is a highly pure methylstenbolone (or 2,17α-dimethyl-5α-androsta-1-en-17β-ol-3-one).  I’ve talked about how difficult this one can be to make pure, but Celtic Labs has indicated Patrick Arnold has tested Celtic Sten and it contains no superdrol (Read – New Methylstenbolone Study Finds SuperDrol Contamination).  I’m not sure how long this compound will last on the market (it’s susceptability towards superdrol contamination makes it hard to produce).  It also seems to have the attention of some anti-doping agency’s like WADA.  Once these organizations draw attention to these prohormones they do not seem to stay on the market long.

Doses for methylstenbolone products range between 14 and 30 mg’s per day.  Celtic Sten contains 90 capsules with 10 mg’s per capsule.  This is a pretty good deal for any methylstenbolone product.  Methylstenbolone is extremely powerful and minimal on physical side effects.  It’s still a methylated prohormone so short cycles of no more than 4 weeks are recommended.  This compound is great for mass building, lean bulking, or even contest prep.

celtic labsCeltibol – This is a methylclostebol (4-chloro-17α-methyl-androst-4-en-17β-ol-3-one) product typically used in cutting cycles.  It is the active form of P-Mag as I described previously (it’s also used in Dianabulk).  Celtibol comes in a 60 capsule bottle with 25 mg’s of active per capsule.  A typical Celtibol cycle can be up to 6 weeks at doses ranging from 50 to 100 mg’s per day.  This compound has somewhat of a cult like following with a few users.  Meaning it’s not necessarily popular with the masses but a few guys really love it to get hard and lean.

Celtic Mass – Celtic Mass is similar in results to Celtibol, but it has been around much longer with a much larger base of user feedback.  Celtic Mass is more commonly known as halodrol (or 4-Chloro-17a-Methyl-androst-1,4-diene-3,17b-diol).  This is just like Blackstone Labs new Halo Elite except it comes in 25 mg capsules.  Halodrol clones are highly reliable, dosed between 50 and 100 mg’s per day, and typically used in cycles 4 to 6 weeks long.  Halodrol is one of my favorite prohormones for lean bulking, or even cutting.

Celti Tren – You have heard of “tren” prohormones before, but this is the first of it’s kind to actually convert to trenbolone in the body.  It is often referred to as trendione or Estra-4, 9, 11-triene-3, 17-dione.  Trenbolone is perhaps the strongest anabolic steroid ever used by man.  It’s effects are game changing and it (actual trenbolone, not the prohormone) is used by high level bodybuilders frequently.  Unfortunately unless it is dosed extremely high it has not lived up to it’s big brother’s standards for most people.  Some guys do seem to react to it similarly to actual trenbolone, but for the most part it has not been as powerful.  Since this is not a methylated prohormone cycles can be longer (6 to 8 weeks).  Doses vary widely, but 90 to 120 mg’s seems to be a good dose for most people.  It is recommended to start lower and work up to that dose.  Celti Tren contains 60 capsules with 30 mg’s per capsule.  Meaning 1 bottle will last 30 days at 90 mg’s per day.

Celtic Epi – It’s actually quite odd that I have not mentioned epistane (2,3a-epithio-17a-methyltioallocholan-17b-ol) much on this site.  I say that because it is something of an old guard when it comes to designer steroids.  Or at least compared to the exotic ones you will read about below.  It also happens to be a very effective methylated prohormone.  It’s been around long enough that we know you can dose it fairly high with relatively safe results.  People have used epistane products on bulks, or cuts effectively.  Cycle lengths range from 4 to 8 weeks, at doses between 30 and 90 mg’s per day (I’ve seen upwards of 130 mg’s +, but I would not recommend it).  There is a ton of user feedback on epistane products over the years.  The general consensus is that it is an effective hormone, and many people like it.  The one caution with it is hair loss in some people, otherwise it provides good aggression, lean body mass, and strength.

Protobol – This is actually an older, less often discussed designer steroid.  Protobol (17a-methyl-5a-androst-17b-ol) is one of the better prohormones for minimal side effects with mild gains.  It’s results can be similar to Epistane and Halodrol, but perhaps to a slightly lesser degree.  Dosing typically ranges from 50 to 150 mg’s per day with most people around 75 to 100 mg’s per day.  Protobol comes in a 60 capsule, 25 mg per capsule bottle.  If you are someone who absolutely fears any side effects, this may be the prohormone for you.

The Exotic Prohormones

Celtic Mass – This is also a close relative of superdrol.  It’s designed to be a diol prohormone to superdrol itself and often referred to as SuperDiol (or 2a,17a-dimethyl-5a-androstane-3,17b-diol).  Since superdrol is now banned the idea was to circumvent the legalities by simply creating the prohormone (converts to superdrol).  This is a methylated designer steroid so it will be hard on the liver, which means keeping cycles shorter is a wise idea (3-4 weeks).

While superdiol is relatively new, it has now been available about a year.  There isn’t a lot of user feedback on this one but it seems it’s “close” to actual superdrol, but higher doses are needed.  I have now seen doses range from 40 to 60 mg’s per day (most common), all the way up to 100 mg’s per day.  Since Celtic Mass comes in 90 capsule, 10 mg per capsule bottles, a large dose like 100 mg’s per day is not only a bit “crash test dummy” but also not very economical.  This was one of the more unique ideas to come from Celtic Labs.

Dianodrol – This is actual dianabol (d-bol) with an oxime group or Methandrostenolone Oxime (17a-methyl-17b-hydroxy-1,4-androstadien-3-hydroxyimine).  The idea is that it will hydrolyze in your stomach from stomach acid, and become dianabol.  The original idea was that this would essentially be a d-bol prohormone, however the user feedback on this compound suggests that it is very dry and not nearly as powerful.  So much so that some people are reporting that it dries out their joints, and is good for fat loss.

When Dianodrol first launched there was a lot of excitement about it being a good bulker.  Since that time the dosages have gone from 45 mg’s per day (3 caps), up to as many as 150 mg’s per day (10 caps) in cycles of 4-5 weeks.  Dianodrol comes in a 90 capsule bottle for a reasonable price.  Most people are now using this compound as a recomposition prohormone or in a cutting stack.  At this point it’s still a little early to call this one a success or a failure.

Dimethabold – This is one of the newest prohormones by Celtic Labs, which means we do not know a lot about it just yet.  Having said that it was designed based on the boldenone structure, but act similar to d-bol.  It’s hard to say what kind of gains Dimethabold will produce as this product literally just shipped to the first users.  At this point if you decide to use it, start at the lower end of dosing (30mg’s per day) and work up.  Cycles should be limited to 4 weeks at this point.

Mestebol – This is one of the more unique prohormones ever made.  Again like Dianodrol it is an “oxime” prohormone.  In the case of Mestebol or Mesterolone-Oxime (1a-methyl-17b-hydroxy-5a-androstan-3-hydroxyimine) it is designed to be a prohormone to proviron, which is an older anabolic known to be a hardener primarily by reducing estrogen.  Meaning it’s not all that powerful, and probably best used when you are extremely lean and looking for a more polished overall look.  Having said all that it’s still to early to trestobolknow for sure how effective this prohormone will be as it just launched in late 2013.  It comes in 35 mg capsules, with 60 capsules per bottle.  So far I see guys dosing it anywhere from 3 to 6 caps per day, which means it can get expensive in higher doses.

Trestobol – I saved Trestobol for last, largely because this has by far been the biggest success (in my opinion) of the entire Celtic Labs prohormone line.  Trestobol (17β-hydroxy-7α-methylestr-4-en-3-one) actually has fairly extensive research behind it’s use in males.  In research it is referred to as trestolone, and it’s been studied as a male contraceptive.  Unfortunately it seems that the pharma companies don’t quite believe it is effective enough for male contraception.  Or perhaps that’s fortunate for prohormone users?

Nonetheless people absolutely love Trestolone as a “test base” and even a pre-workout androgen to increase aggression.  It does aromatize to estrogen, so having an aromatase inhibitor on hand is especially important.  At the same time you can literally stack it with almost anything and it will help maintain energy and libido.  It will add weight to your frame fast, and it is a great bulker.  Trestobol comes in a 100 capsules, 10 mg per capsule bottle.  Doses range significantly from 30 mg’s pre-workout to as much as 150 mg’s per day.  50 mg’s is the most common dose.  Cycles of trestolone can be ran fairly long with reasonably safe results.  I would not be afraid to recommend 6 to 12 weeks depending on what you are stacking.  Overall this is a great oral option for libido, energy, size, and strength.  And it’s hard to argue against a hormone that does all those positive characteristics.

M1T-Oxime – This one was added after this article was written.  For the full details on M1T-Oxime check out this – Celtic Labs M1T-Oxime Launching
