I'm for a group buy for both. In note to whomever is willing to organize the Group Buy: another member and I recently teamed up to purchase Epitalon from Genscript and got a very good price from them. I'm running out of Epi however, and wish to try higher dosages. I'm interested in buying both Epitalon and Thylamin. However, I have reserves about the later. I purchased 100mg of Thylamin from Ceretropic that I took in conjunction with their Epitalon. Their Epitalon was however far more effective when combined with TB-500 than with their Thylamin. Either the Thylamin isn't potent, or it doesn't have noticeable immediate effects, or TB-500 has greatly noticeable immediate effects that eclipsed the Thylamin's joint intake with Epitalon. II noticed this in only three days of 2mg/day intake of TB-500 while 5mg/day are best for a full ten day run of both. I would recommend adding an option of TB-500 to the Group Buy. FWIW.

I found Ceretropic's Epitalon combined well with the false Thymalin that Peptide Sciences vends, that is not really the Khavinson Thymalin (glu-tryp), but Thymulin, an older and different iteration of a thymic peptide. It is not a bi-peptide, but a much longer peptide chain.
I found the combined two to be quite effective at eradicating numerous severe lesions on my calves that were caused by exposure to a toxin. I don't think that Epitalon all by itself works as well as it does with SOME version of a thymic peptide, but this is just subjective.
I have used the Peptide Science false Thymalin one other time, with good results. (Ceretropic is now also vending the false Thymalin.)
TB-500, I get from a vet store, so I know that it is real as it must be FDA-approved. It has amazing healing properties. I don't know that its effects will equal true Thymalin (glu-tryp), though.
Based on my experiences and all that I've read I want to try true Thymalin with Epitalon, as together they should produce noticeable effects.
I have used it with N-acetyl Epitalon from Ceretropic. I can't say that anything acute changed, as I had no problems like the calve lesions.
