It sounds to me like typical "test flu" symptoms. I actually just went through it for about 8 days. I've been on 100mg prop eod, and 200mg TE e4d for 11 days now.
The past 2 cycles Ive done, ive experienced this bullshit. Prior to that Ive never gotten sick during the start of a cycle. Ive done 6 cycles total over the last 8 years.
