Tev-Tropin is a brand name synthetic growth hormone.
In medical scenarios, it’s known as somatropin, which merely defines it as man-made.
It is manufactured by utilizing rhGH technologies.
It’s a prescription-only drug intended for use on mainly children to encourage growth in stature, but it’s also used on children as well as adults to increase muscle growth.
It has also been used to treat individuals diagnosed with very low growth hormone levels and short stature. Tev-Tropin was discontinued as a medically recommended synthetic growth hormone for treatments in the US.
In some cases, discontinuation of the drug is not caused by its dangers of use or side effects but because newer, more stable drugs have been developed in its place.
Tev-Tropin, manufactured utilizing rhGH technologies, contains recombinant DNA origins.
Actually, it’s a polypeptide of recombinant DNA with the same number of amino acids that is produced by the human pituitary gland (191).
Recombinant DNA technologies combine two, sometimes three or more different strands of DNA from different origins to create a synthetic drug designed to mimic the activity and performance of substances found in the body.
It contains a strain of E. coli, (Escherichia coli) modified by a human growth hormone gene.
When it was manufactured, Tev-Tropin was available in 5 mg or 10 mg vials.
Each 5 mg vial contained 5 mg of the recombinant somatropin and 30 mg of mannitol.
The 10 mg vial also contained 10 mg mannitol, 3.57 mg disodium phosphate dodecahydrate, and a 0.79 mg sodium dihydrogen phosphate dehydrate.
The larger volume vial also came with diluting solution. Both forms were sold with a diluting solution that needed to be mixed with the synthetic growth hormone prior to injection.
That is how the original product was manufactured. In the US, underground labs developing their own versions of Tev-Tropin for sale may or may not contain similar ingredients.
Tev Tropin Injection Uses
Benefits of Tev Tropin uses can be considered fairly consistent between medical and non-medical use.
Non-medical use of growth hormone was never condoned nor recommended by medical professionals around the world.
Tev-Tropin was/is known to enhance:
bone growth (stature and strength)
metabolism of protein, carbohydrates, lipids, minerals and connective tissues
retention of nitrogen
Half-life: approximately 30 minutes (0.1 mg per kilogram of Tev-Tropin).
In medical scenarios, dosage and administration guidelines generally followed the 0.1 mg per kilogram of body weight. In some cases, dosage started lower at .005 mg per kilogram.
This dosage was to be given three times weekly via subcutaneous injection.
Physicians would carefully supervise patients for side effects at such dosages, making slight adjustments as needed.
Recommended subcutaneous (under the skin, and not into deep muscle) injection sites for Tev-Tropin are located on the back of the upper arms, the abdomen, or the fatty or more muscular areas of the trunk.
This includes the buttocks, and the anterior and posterior surfaces of the thighs.
Bodybuilders using Tev-Tropin or any type of growth hormone tend to take more than medically recommended for accelerated benefits.
However, most bodybuilders take an average of 1 (one) IU to 6 (six) IU daily.
Use of growth hormone in regard to dosage is a matter of personal preference for most bodybuilders depending on their expectations and goals.
Note: 1 mg is roughly equivalent to 3 IU (international units)
Bodybuilders using Tev-Tropin or other types of growth hormone would cycle its use anywhere from six weeks to six months.
The higher the dosage and length of cycle, the greater the risk of interference with otherwise normal hormonal and metabolic functions in the body.
The same goes for other substances such as anabolic androgenic steroids combined with the administration of the synthetic growth hormone.
Stacking With Tev-Tropin
Bodybuilders often combined some form of synthetic growth hormone (somatropin) with other drugs to boost responses. Among them:
Thyroid drugs (such as T3 known as Triiodothyronine)
Anabolic androgenic steroids (any)
Such stacks are not recommended for most bodybuilders due to the serious risk of detrimental side effects. Some of these side effects can be life-threatening.
Manufacturers of Tev-Tropin caution patients against exceeding recommended dosage of a 0.1 mg per kilogram body weight three times weekly.
Doing so could trigger hyperglycemia or hypoglycemia due to its influence on hormones.
Tev-Tropin Side Effects
Tev-Tropin usage is not as common today, but even among bodybuilders should still be carefully monitored by physicians for potential side effects. Among them:
skin lesions (could develop into malignancies)
increased insulin sensitivity, especially in those with undiagnosed glucose intolerance
nausea, sometimes accompanied by vomiting
changes in vision
intracranial hypertension (with or without papilledema or swelling of the optic discs in the eyes)
Acromegaly is also a possibility due to excessive growth of bone, muscle, and connective tissues.
While Tev-Tropin and has been discontinued in numerous medical environments, bodybuilders seeking adequate substitutes from underground labs should always proceed with caution.
