Tamoxifen (Nolvadex):
Reputation: Most popular SERM for PCT
Pros: Cheap. Effective for gyno prevention.
Cons: Heptatoxicity. Studies have shown it to lower IGF levels (I don't feel like citing, but it's about 20% decrease...IMO no biggie).
Popular Dosage (for a 4-week cycle): 40/40/20/20
Note: Tamoxifen Citrate is less potent, and should be dosed at an extra 30%.
Most tamox pharm tabs are tamoxifen citrate, and are labeled in tamox content only. I'm not sure about exact citrate numbers, but if a tab is labeled 20mg tamoxifen, it's actually 20mg tamox and 5mg? citrate. I forgot what the citrate is there for, but with pharm tabe, if you want 20mg dose, take a 20mg tamox tab. For research chems, no idea...
And yes, tamox tabs are CHEAP, 2-3 cents per mg. Torem is about 6-7 cents per mg, more than 2x the cost of tamox per mg, not to mention that it has to be dosed 2-6x as high. Some people love torem, but some people don't need torem. It all depends on the person. Gotta try both in separate cycles to know how your body responds.
