Alternatives to HCG for preventing testicular atrophy.

I've used both ZyhCG and Sifasi. They have health questions and a place to send a prescription but you don't have to. I've never had a box diverted by customs. I've bought acne creams, antibiotics, nebivolol, metformin and other such common medications.
Thanks.
Do they send the hCG from India or some other country?
 
When you asked last year I came up with 18: pregnenolone, DHEA, progesterone, kisspeptin, GnRH, LH, FSH, estradiol, prolactin, DHT, hepcidin, androstenedione, androstenediol, cortisol, TSH, T3, T4, rT3...

To this we might be able to add dynorphin, neurokinin B, GnIH, ACTH, aldosterone and others. In some cases the pathways are less direct, but influence is still possible.

It's worth mentioning that Dr. Mark Gordon says it's 35 hormones in the video linked here [around 15:30]. From this we might add allopregnanolone and GABA to the list.
Thanks, Cat

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
