01 Overview

Andarine (GTx-007, S-4) is an investigational selective androgen receptor modulator (SARM) developed by GTX, Inc for treatment of conditions such as muscle wasting, osteoporosis and benign prostatic hypertrophy, using the non-steroidal androgen antagonist bicalutamide as a lead compound.

Andarine(S4) Description:

As said earlier, SARMS function by tying to the AR resulting to anabolic activity. Due to this binding and stimulation, more protein is produced which allows muscle building. S4 can trigger muscle development in the same way as steroids, but minus the same unwanted side effects the latter has on the prostate and other sexual organs.
How it’s used depends on what effects you’re looking after. Fat loss or cutting is the most effective use for S4 Andarine.


Andarine(S4) Usage:
Andarine (GTx-007, S-4) is an investigational selective androgen receptor modulator (SARM) developed by GTX, Inc for treatment of conditions such as muscle wasting, osteoporosis and benign prostatic hypertrophy, using the non-steroidal androgen antagonist bicalutamide as a lead compound.
Andarine is an orally active partial agonist for androgen receptors. It is less potent in both anabolic and androgenic effects than other SARMs. In an animal model of benign prostatic hypertrophy, andarine was shown to reduce prostate weight with similar efficacy to finasteride, but without producing any reduction in muscle mass or anti-androgenic side effects. This suggests that it is able to competitively block binding of dihydrotestosterone to its receptor targets in the prostate gland, but its partial agonist effects at androgen receptors prevent the side effects associated with the anti-androgenic drugs traditionally used for treatment of BPH.
Andarine S4 is a SARM that was developed for treatment of muscle wasting, osteoporosis and benign prostatic hypertrophy. S4 is effective in not only maintaining lean body mass, but increasing it while reducing body fat.


Great effect of S4 Andarine :
1. 1/3 as androgenic as testosterone in muscle tissue.
2. Anabolic at doses above 50mg
3. Great for strength
4. Great for muscle hardness
5. Great for enhanced vascularity
6. Great for endurance (aerobic or anaerobic)
7. Accelerated fat loss above 50mg
8. Joint healing effects


Side Effects of Andarine (S4):
As with any compound or chemical, there are benefits and side effects. Understanding both sides and what you are getting yourself into with use is key for your health and longevity. Always keep in mind, some drugs carry more side effects than others. However, side effects can be controlled, mitigated or eliminated, yet they need to be taken very seriously and addressed accordingly. Read further to understand the side effects of Andarine (S4) use and how to avoid and mitigate them during your cycle.


Overall Dosing Protocol:
The following protocol is something that I developed to help a user mitigate and hopefully avoid extreme vision effects from occurring.
I compare this protocol to fighting Mike Tyson on Mike Tyson’s punch out. If anyone has ever played the game they will appreciate this comparison. When you fight Mike Tyson, the first 1:20 seconds of round 1, if you’re hit just one time you are knocked down. This is the danger zone. Once you get past that first 1:20, you are much safer, but you still must proceed with caution as there is constant danger present if you let your guard down.
The same idea goes for andarine (s4). You need to ease into the first 2 weeks at an average dose of 25-50 mgs. If you are able to get through the first 2 weeks with minimal or no side effects, then you have made it through the danger zone. You have reached a point where you can increase your dose to 60 mg, but it is imperative to proceed with caution. This is a testing phase. You must now stay on 60 mg between 10-14 days. After this point, it’s alright to increase your dose to 70 mg. The sweet spot for dosing is between 70-80 mg per day. The optimum dosing would be to use S4 at around 100 mg per day, but most users are unable to get to this point. Continue to follow the 10 mg increase pattern throughout your cycle until your reach the bottom of your level of comfort. Do not exceed 100 mg per day. Do NOT rush to increase dosage, it will not yield more results – just more side effects. Following this protocol will be the safest and most effective way of dosing andarine.

Andarine (S4) is highly beneficial, and if a complete cycle is implemented, the results will leave a user more than satisfied. Understanding the side effects and how to properly use S4 is of the utmost importance. Make sure that the dosing protocols are followed and all safety precautions are taken. If you do that, there will be a far greater chance of maximum gains made while health and longevity remains.

Week Andarine (S4)
1 25mgs/ED
2 50mgs/ED
*At this point you must judge the vision sides. If they are minimal, increase dosages by 10mgs; if you’re not comfortable, decrease doses back to manageable levels (around 25-50mgs range).
3 60mgs/ED
4 60mgs/ED
*If you feel the sides are alright at 60mgs, you can move up to the magic 70-80mgs range.
5 70mgs/ED
6 70mgs/ED
7 80mgs/ED
8 80mgs/ED
9 80mgs/ED
At this point, you are probably one of the guys who gets little sides or very manageable sides from andarine. You can move up to the super sweet 100mgs/ED. ONLY if you’re comfortable.
10 90mgs/ED
11 100mgs/ED
12 100mgs/ED
