How do you know it's not worth the extra price?
Strictly from personal experience and no bloodwork - but after using HMG 75iu once daily (Sub-Q via slin pin) for a 2 week period, libido was restored to beyond what I expected, balls were bigger, loads were huge, plus my muscles were full. I had a great sense of well being. HMG acts quicker than HCG so you might see people recommend twice daily injects but I had great results on once daily. If you're on cycle I'd recommend 75iu twice per week for 4 week bursts at at time.
PCT I'd probably use it 75iu ED for 2 weeks by itself.
My other option is to take 20mg of aromasin the day before a relatively large 1000iu HCG shot (1000iu in clinical studies isn't large - but to me it is). That way I don't get the estrogen spike that HCG seems to do.
75 ED? Hell, I did a half vial once and felt the effects all week. I won't do another until I feel the boys need a boost -- probably in a couple of months.
Not sure why people are saying it's a last resort. Same as HCG, just better.
