ONARMOR facts, about using Test Prop 100mg/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.  

Testosterone Propionate (TEST PROP) is a common injectable form of testosterone. The added propionate ester will slow the rate in which testosterone is released from the injection site, but only for a few days. TEST PROP is, therefore, comparatively much faster-acting than other testosterone esters such as Cypionate or Enanthate, and requires a much more frequent dosing schedule. It is a powerful mass-building drug, capable of producing rapid gains in both muscle size and strength. TEST PROP also has a significant place in any cutting cycle where there is a requirement to maintain a level of testosterone within the stack.

Structural Characteristics:

TEST PROP is a modified form of testosterone, where a carboxylic acid ester (propionic acid) has been attached to the 17-beta hydroxyl group.

Esterified forms of testosterone are designed so that the testosterone is absorbed more slowly from the area of injection. Once in the bloodstream, the ester is removed to provide free testosterone. Esterified forms of testosterone are designed to extend the window of effect following administration, allowing for a less frequent injection schedule compared to injections of free testosterone. The half-life of testosterone propionate is approximately two days after injection.

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

Testosterone is the benchmark against which all other hormone/steroid products are judged and the product which should usually be part of any cycle and stack. It is an easy product to use and get used to as the side effects are usually minimal.

TEST PROP is usually incorporated into bulking phases of training, when, should there be any, water retention will be of little consequence, the user is going to be more concerned with raw mass than definition. TEST PROP is however commonly used in cutting and competition preparation phases where the competitor wants to keep a maintenance dose of testosterone in their system, to support the body’s hormone balance, whilst relying upon other products, such as TREN and MAST to form the major part of the cutting cycle. The other added benefit, for competitors worried about screening, is that TEST PROP is out of the system very quickly when compared to the other TEST products.

Now for beginners looking to “bulk up” and put on lean muscle we wouldn’t recommend TEST PROP over the longer estered variations, such as TEST ENAN 300, due to the fact that the product requires more frequent administration (injections every day or every other day). It also has a much lessor dosage. It will be easier for the non-competitor to facilitate the use of Sustanon, Cypionate or Enanthate. Also for those athletes and older serious gym goers that choose to “cruise”, rather than stop the use of testosterone during the period in between cycles, test prop might not suit this requirement. Rather the use of a longer ester product would be a better product of choice.


ONARMOR Test Prop is dosed at 100mg/ml.

In terms of dosage, the usual dosage among most athletes is in the range of 50-100 mg per injection, TEST PROP is commonly taken on a weekly dosage of between 200 mg to 1000 mg (depending on the type of cycle the user is on). For those new to the use of steroids and injectables, such as TEST PROP, our suggestion is to be restrained. Keep to a lower/medium dose per week over the duration of a course in order to get used to using these hormones.

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 a good practice to have someone else, responsibly, administer injections.


TEST PROP 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.
