ONARMOR facts, about using Test 400      400mg/ml

General Description

ALL On Armor injection Oils are adapted to incorporate a pH balanced formula that should reduce/eliminate pain at the point of injection.  

All Testosterone products, regardless of the ester, are superb performance enhancers, promoting muscle growth, strength, recovery and endurance. ONARMOR TEST 400 has a dosage of 400mg of Testosterone per ml of oil, with a performance dose of TEST 400 in your body will have a higher threshold for more intense training sessions, you will recover faster and you won’t get as tired.

The testosterone hormone is both a highly ANABOLIC and ANDROGENIC. The administration of Testosterone into the body greatly increases nitrogen retention in the muscle tissue. Nitrogen retention allows more protein to be absorbed into the system which essentially instigates the building of lean muscle tissue. An increased level of testosterone in one’s system is excellent at keeping the hormones under control that destroy muscle tissue and promote body-fat accumulation. Testosterone characteristically binds to androgen receptors, as a result, that promotes extreme muscle gain, fat reduction and tissue repair. Through the use of hard and longer training sessions, the muscle fibres are traumatised, after this training, when we are resting is when the body starts its recovery and repair, muscle growth. The use of testosterone makes this process more effective and quicker.

TEST 400 will allow you to train far harder and for far longer durations. With this type of longer, harder training sessions more progress will be made. TEST 400 provides incredible performance enhancement for all levels of athlete and serious gym goer alike.

Test 400 incorporates a unique mixture of a number of advanced testosterone esters allowing the body to absorb the testosterone fairly quickly from the outset, but delivers the whole dosage over a longer period of time.

Test 400 is a unique blend of Test Cyp / Enan / Decanoate, delivering massive 400mg of testosterone per ml. A hugely popular product for those guys who want to pile on massive size and strength and those who require large weekly dosages without too much hassle. It is our most powerful testosterone product within the test range. Whilst Test 400 is a high dosage, the unique blend will ensure that, even with administrations of 2ml or more, there is little injection pain.

As with all other Test products, if you maintain a good diet plan, then a Test 400 cycle will provide massive lean muscle mass. We would recommend the use of an Aromatase Inhibitor with Test 400 due to it’s high dosage.

With bodybuilders and serious gym goers in mind, the most common use of TEST 400 is for piling on serious mass.

Structural Characteristics:

Testosterone 400, as with all of the testosterone products made by ONARMOR, is a modified form of testosterone, where an acid ester is attached to the 17-beta hydroxyl group. Each type of esterified product, depending upon the type of ester, allows the body to absorb the testosterone over a shortened or prolonged period of time. Once in the bloodstream, the ester is removed to yield free (active) testosterone.

The half-life of Testosterone 400 is approximately 18 days after injection.

Cutting through the Jargon, what is it like in practice?

As with all Test products, TEST 400 is an absolute brilliant product, one that should not be overlooked against perhaps more exotic compounds; it is a fantastic all-rounder and the benchmark against which all other hormone/steroid products are judged. The inclusion of any ONARMOR testosterone product into any cycle or stack is a good choice, in fact, in our opinion an essential choice for male users. It is an easy product to use, there are various dosages and absorption rates to choose from, and for most users the side effects are usually minimal if not zero. In most cases the side effects of using any testosterone product (these may not increase in direct relation to increases in dosages) are:

·        Slight water retention, which can be overcome with the use of a suitable Aromatisation Inhibitor such as Anastrozole.

·        A substantial increase in libido

·        Improved mood and confidence

·        Higher energy levels and less fatigue generally

Test 400 is usually used in the bulking phase. When you may not be too worried about water retention and muscle definition, rather you are going for pure size, raw muscle mass. It is a perfect product when you want to increase your weekly dosage, for those who want to incorporate serious Test Dosages into their cycle. It could be incorporated into a cutting phase but we would suggest keeping the dosage low and using products such as Tren E or Mast E, or both to make up the overall weekly dosage.   

Generally it is an easy product to use and well tolerated by most. Some can get a little “PIP” when they first start to use TEST 400 over other TEST products such as CYP. Any pain issues usually stop after the first two or three injections, however, we do strongly suggest not trying to administer more than 1ml into one single injection point.


ONARMOR Test 400 is dosed at 400mg/ml.

Test 400 has an extremely high dose at 400mg/ml is ideal for a massive cross section of trainers and advanced gym goers. The dosage of 400mg/ml is ideal for anyone taking 200mg to in excess of 1000mg per week. Injection intervals should be two or more per week to keep the dosage at the required level without drop off.  The long esters and subsequent slower absorption rate means less frequent administration and with increments of 400mg easily calculated and added in the administration regime, experienced users can increase weekly dosages gradually until the ideal dosage is achieved. Test Enan is also an excellent choice of product for those wanting to cruise during “down time” and for those who administer to increase libido and reverse the effects of andropause and fatigue.

In terms of Test 400 dosage, the usual dosage among most athletes is in the range of 400 - 800 mg per injection, depending upon the size of barrel (syringe) used 1 or 2.5ml (please see our previous comments on how much to use in one single injection point). A normal range for this product would be 400 – 1200mg. It is an ideal product for those performance athletes who wish to use beyond 1200mg a week.

Please note: all ONARMOR products are exactly dosed and may exceed the dosages experienced with other similar products by other manufacturers. We would suggest starting at a lower dosage and increasing steadily throughout the weekly course. Should you experience any adverse side effects at higher dosages this will allow you to “back off” the dosage down to a level that you are ok with.

In general terms we would suggest the following weekly dosages for maximum muscle mass (not as part of a cutting phase):

Beginner              400 mg/wk

Advanced Beginner 400 – 1200mg/wk

Advanced 1200+ mg/wk

Note: good, hygienic, injection practice should be applied at all times. All sites should be clean (it is a good practice to carry out administration after showering or taking a bath) and should be treated with a wipe. Do not attempt to use previously used equipment or share equipment. It is good practices to have someone else, responsibly, administer injections.


As with ALL Testosterone products, Test 400 will stack well with any other steroid product. Each athlete should be sure of their objectives when creating a stack and with experience they will be able to fine tune these stacks to achieve quite specific results at the end of each cycle.
