1. Pass company's reproductive hormones are synthetically synthesized. So these products are significantly cheaper than pituitary.
2. Pituitary gland is a general gland in the body that controls almost all physiology and homeostasis of the body in addition to reproduction, so it is not possible to prevent the severe damage of pituitary extracts caused by the unwanted effect of the secretion of other hormones and chemicals in the pituitary gland.
3. With long-term use of pituitary extracts, substances (antimatter) can be secreted by the fish brood, which after a few years leads to the loss of the sensitivity of the brood to the pituitary extract. Pas company's products are not immunogenic, so they maintain their effectiveness even with repeated use in the same generator.
4. Treatment with PASS hormones mobilizes the release of endogenous gonadotropin hormones (GtH) in fish.
5. Unlike hypophysis, Pas company's products are easy to maintain, use and inject, and do not require specialized training for use.
