GP Sust 270 (Sustanon)


GP Sust 270 (Sustanon) – Manufacturer: Geneza Pharmaceuticals Pharmaceutical name: Testosterone blend Pack: 10 ml/vial (270 m



GP Sust 270 is a blend of four different Testosterone esters: Testosterone Propionate (30 mg); Testosterone Phenylpropionate (60 mg); Testosterone Isocaproate (60 mg); and Testosterone Decanoate (100 mg). GP Sust 270 is designed to provide a fast extended release of Testosterone. The Propionate and Phenylpropionate esters in this product are quickly utilized, releasing into circulation within the first four days. The remaining esters are much slower to release, staying active in the body for about two and three weeks respectively.

As with all Testosterone products, GP Sust 270 is a strong anabolic with pronounced androgenic activity. It is mainly used as a bulking drug, providing good gains in strength and muscle mass. Although it does convert to estrogen, as is the nature of Testosterone. This anabolic injectable steroid is noted as being slightly more tolerable than GP Test Enanth 250 or GP Test Cyp 250.


With GP Sust 270, blood levels of testosterone are building more slowly, so side effects do not set in as fast. For equal blood hormone levels however, Testosterone will break down equally without regard to ester. Also correlating with estrogen, water retention would be noticeable with GP Sust 270, unless steps were taken to minimize estrogen.
Being a strong androgen, we can expect the typical side effects. This includes oily skin, acne body/facial hair growth and premature balding. The addition of Prosterit should be able to minimize such side effects, as it will limit the conversion of Testosterone to DHT (Dihydrotestosterone).


GP Sust 270 will suppress natural testosterone production rather quickly. The use of HCG and/or GP Clomiphene/ GP Nolva are necessary at the conclusion of a cycle in order to avoid a hormonal crash. Remember though, Sustanon will remain active in the body for up to a month after your last injection was given. Beginning you post cycle drug therapy immediately after the steroid has been discontinued will not be very effective. Instead, HCG or GP Clomiphene/ GP Nolva should be delayed three weeks, until you are near the point where blood androgen levels have dropped significantly.


Although GP Sust 270 remains active in the body for approximately three weeks, injections are taken at least every 10 days. An effective dosage ranges from 250 mg per week to 1000 mg weekly. Some athletes do use more extreme dosages of this steroids, but this is really not a recommended practice. When the dosage rises above 750-1000 mg per week, increased side effects will no doubt be outweighing additional benefits. Instead of taking unnecessarily large amounts, athletes interested in rapid size and strength will usually opt to addition another compound. For this purpose we find that GP Sust 270 stacks extremely well with the potent orals GP Oxy and GP Methan 10. On the other hand, GP Sust 270 may work better with GP Tren Acetate 100 or GP Stan 50 if the athlete were seeking to maintain a harder, more defined look to his physique.
