GP 1-Test Cyp is a product that contains 200mg of the Dihydroboldenone Cypionate.
Dihydroboldenone, most commonly known as 1-testosterone, is a 5alpha reduced form of the steroid boldenone. This lack of 5alpha reduction with the compound allows users to administer it without suffering the negative side effects associated with this chemical reaction but also eliminates the benefits as well. Boldenone is not the only steroid that shares similarities with dihydroboldenone. In fact dihydroboldenone is chemically identical to the drug methenolone except for the 1-methylation that is apart of methenolone (1). 1-methylation was of course added to methenolone to make it more available when taken orally and thus dihydroboldenone is not efficiently utilized when administered orally, although it was once sold over the counter in tablet and pill form. Some of these over the counter preparations of the drug were done utilizing a delivery system similar to Andriol, i.e. producing an oil-solubilized product with dihydroboldenone. This would still not be a relatively worthwhile system of delivery to use however if one wanted to maximize the potential of the compound. Intramuscular injection is by far the most efficient method of administration to use as with most anabolic steroids.

As mentioned above, dihydroboldenone is structurally similar to methenolone and boldenone and less so to testosterone despite the commonly used name for it, 1-testosterone. For this reason some female athletes may be inclined to use the drug as well. The potential for development of symptoms of virilization still remain but are not as severe as with synthetic testosterone or other harsher drugs. This is not to say however that dihydroboldenone is a mild drug. To simplify the explanation of exactly what the drug is, it is to boldenone as dihydrotestosterone (DHT) is to testosterone. This would explain why the effects of the drug, both positive and negative, are so dissimilar to those of boldenone. Like testosterone and dihydrotestosterone, a portion of the boldenone that a user administers converts to dihydroboldenone. Also similarly, dihydroboldenone like dihydrotestosterone does not convert to anything else past that compound.

The frequency of dosing with dihydroboldenone depends on the ester used with the compound. Seemingly the most popular current ester to produce the drug with is cypionate. Typcially, males would use a dosage of 200-400mg Dihydroboldenone Cypionate a week.
