Warning: This review is long, so if you are going to sit down and read it all the way, you may want to grab a quest bar or two and a can of cola :)
Today, I shall publish the long anticipated review of the Iron Mag Labs SARM-based anabolic known as Osta rx. Before I begin the synopsis, I want to extend a special shout out to my fellow SARMinator loggers Abailey and BrooklynBuff who joined me in the SARM battle. I also want to especially thank everyone who joined and supported me, BB, and Abailey during the log.
Okay enough hugs and kisses, time to get down to business.
Osta rx is a unique supplement with the active ingredient Ostarine. Ostarine is a selective androgen receptor modulator (SARM) that has been demonstrated to exhibit anabolic activity in both skeletal and muscular tissue. It is worth noting that ostarine is also known as MK-2866.
Ostarine and SARMS in general have been demonstrated to have the following benefits:
Increased Muscle Mass
Increased Aerobic and Anaerobic Endurance
Reduction in Bodyfat
Increased Muscular Strength
Of course, it is improtant to keep in mind that these benefits are achievable best when combined with proper diet and intensive training in addition to SARMs or any anabolics.
Now a question many tend to ask is, "How do SARMs work?"
Based on my own research this is basically how these compounds work:
As the name "selective androgen receptor modulator" suggests, SARMs like ostarine work by binding to and activating the androgen receptor. Activation of this receptor results in an alteration of gene transcription co-factors via a pathway of signaling cascades. This alteration results in increased protein synthesis within target tissue, whether muscular or skeletal. Increased protein synthesis, as many would know, directly translates into muscular hypertrophy.
It is interesting to note that many of today's best-known anabolic steroids actually work via similar pathways and mechanisms. However, the advantages of SARMs in comparison to steroids include no toxicity, little to no suppression, little to no negative health impact, and high oral bioavailability without risk to organ integrity.
What I've discussed is a only a general synopsis of the overall basics of Ostarine and SARMs overall. I strongly suggest that anyone seeking more info on a proper cycle to extensively research Ostarine by checking out some SARM threads fellow members have posted or simply using Google (or Bing).
Now I will discuss my own personal experience with osta rx.
Taste N/A: The pills are yellow, tasteless, and easy to swallow. No bad aftertastes or digestion issues.
Ingredient Profile (9): Three caps a day provides about 20 mg of the active ingredient SARM; osta in this case. It also provides of 672 mg blend of the following support ingredients:
Horny Goat Weed
Vitamins B-6 and B-12
Safe to say, having a blend of support ingredients to help sustain test levels is always a nice bonus. I just wish they weren't in a blend as I hate prop. blends. To important thing though is that there is a substantial dose of Osta itself. 20-25 mgs is said to be the effective does for many users.
Usage: Dosing protocol is relatively simple. Ostarine has a 24-hour half-life meaning that only one target-quantity dose is needed. The directions suggest to take no more than three caps a day and spread them throughout the day. However, similar to how Jpotter used osta rx, I just took all three capsules in the morning. This provided with the substantial does of the ostarine to last a full 24 hours until the next day's dose. I found this to be the most convenient way to take it.
Effectiveness: As most previous users who've reviewed this product I will detail my achieved benefits in categories based on what is expected from the product. Beforehand I want to make note that I was using the following additional supps during my entire 8-week run and the ones I incorporated into pct:
Supp-d (added around week two when it arrived)
DCP 2.0 (added around week four when it arrived and in pt)
Recelerator (used throughout the cycle with a brief break mid-cycle)
MTS Machine Whey (used throughout)
360 post-workout (added mid-cycle)
Orange Triad (used throughout)
King Mass (used solely in PCT when it arrived)
Creignite (used primarily in pct)
Testogen XR (used primarily in pct)
T-blast (PCT only)
New G8 (added around final week of cycle and used throughout pct)
So now I will gauge the efficacy in my categorical analysis. I should note that these benefits began to show full force around the beginning of week 4, while some were prominent somewhat earlier and even enhanced during pct..
Strength (9): I was setting some noticeable PR's around both in terms of number of reps and amount of resistance. Below is a list of my most notable final PRs while on Osta and following my PCT:
Deadlift: 535 lbs from 525 lbs
Bench Press: To be honest I kind of plateaued on this lift, but I would say that I finalized a power max load of about 345 lbs. Still up from 340 lbs.
Squat: Really progressed on this lift!!! Original power max was about 405 lbs. Following completion of the cycle and pct, my new PR is now 425 lbs.
Trap-bar deadlift: Once I got into the groove of this lift, my final PR was 440 lbs, up from 410 lbs.
These were my most noticeable PRs, but I also set some new weight bearing and volume based PRs on several other supplementary lifts such as dumbbell curls, leg presses, weighted dips, weighted chin-ups, and military presses.
Vascularity/Pump (9): Vascularity and pumps were incredible with osta and even more phenomenal when I threw in supp-d and DCP 2.0 into the mix. Veins a very prominent and pumped up most noticeable in my shoulders, chest, and arms.
Libido (10): While I am sure the support ingredients such as the horny goat weed and fenuside were more responsible for this, my libido on osta rx was through the roof. Unfortunately, Mr. Johnson didn't have anyone to share his vitality with, IT FOOING SUX TO BE SINGLE!!!
Endurance (10): My endurance was very much improved as the cycle progressed. I've always had pretty good stamina, but Osta rx definitely helped improve it. I found myself running at higher speeds for longer periods of time and having more aggressive boxing trials. When I added my weight vest, the endurance was really tested and I experienced in even further progression. Overall, muscle integrity was also very good as I found myself banging out more reps on more difficult lifts.
Fat Loss/Recomp Effect (7): The increase in stamina helped to translate into some decent fat loss thanks to more intensive cardio. However, I give it only a "7" because it wasn't until I added DCP 2.0 that I really started getting a good thermo effect and noticing more definition. Therefore, osta rx alone slightly lags in this area, but was not totally absent in this benefit.
Muscle Mass (8): I gained anywhere from about .5-1.5 inches in several muscle groups including arms, chest, legs, and shoulder frame. Had I had my caloric intake maybe a bit more, I may have been able to put on more size, but gains of any kind are welcome.
Mood (10): Mostly thanks to the L-dopa in Osta rx, but my mood was consistently positive while on this. Always felt motivated to do anything at anytime.
For a final score in efficacy, I give Osta rx an 8.5. Remember, SARMs may work in a similar mechanism as most AAS compounds, but DO NOT expect gains of similar nature. Had this been a review for something like M-Sten and I achieved only these gains, the score would be much lower. It is important rate efficacy on the product's known effects and to the degree the effects are known to be exhibited.
Sides: I recall BrooklynBuff and Abailey complaining of occasional headaches while on osta rx. I also saw some blogs of users reporting similar effects as well as suppression symptoms around week 6. If I am not mistaken, I believe Jpotter and Garlick reported suppression around the later weeks of their cycles.
For me personally, I actually experienced none of this. Even at 6 weeks, I had no signs of suppression i.e lethargy, lack of libido, etc. The only real side I got I guess would have to be some brief aggression outside the gym. Other than this though, side effects were virtually absent.
Value (5): Osta rx is not cheap, to say the least. The price for one bottle range from 69.99 to as high as 79.99 to what I've seen up to today. I was able to get my bottles on Amazon for about 54 dollars a bottle, thanks to a Amazon Prime deal. As effective as I found osta rx to be, you'd think that something of such a more mild nature would be cheaper. However, then again, there are some companies out there who overprice their natty test boosters so, I won't bash osta rx too heavily. Still, in this economy, expensive is expensive.
Overall (8): In final conclusion, Osta rx truly did deliver in several areas. Combined with proper diet, intensive training, support supps, and a decent pct, one can expect some decent gains from osta rx in strength, endurance, and recomposition. Just do some shopping and ensure that you have enough for a substantial 8-week cycle.
