SERMs & PCT
Our SERMs and PCT range covers the compounds researchers use to study oestrogen feedback and recovery of the hypothalamic-pituitary-gonadal (HPG) axis: Nolvadex (tamoxifen), Clomid (clomiphene citrate) and HCG 5000IU.
How SERMs and PCT compounds differ
Selective oestrogen receptor modulators block oestrogen at some tissues while activating it at others. For example, tamoxifen strongly blocks breast tissue receptors, whereas clomiphene acts mainly at the hypothalamus to raise LH and FSH. HCG works differently again, because it activates the LH receptor directly in the testes or ovaries. As a result, many protocols compare a SERM with HCG to separate central and gonadal effects.
Why researchers order from Vi Corpus
Every order ships from Australian stock. In addition, weekday orders placed before 12pm AEDT leave the same day, so most metro labs receive them within days. Batches are third-party tested, and reports are available through our Lab Tests page.
SERMs and PCT FAQ
What does PCT stand for?
PCT means post-cycle therapy. In research, it describes protocols that study hormone recovery after androgen receptor suppression.
Are these compounds prescription medicines?
Yes. Tamoxifen, clomiphene and HCG are prescription medicines in Australia, so we supply them for laboratory research only. Related SARMs are in our SARMs Australia range.
